Windows Key


Alternatively referred to as the winkey or WK, the Windows key is found on the keyboards of IBM compatible computers running the Microsoft Windows operating system. The Windows key (shown right) has the Microsoft flag logo on it and is located between the CTRL and ALT on the keyboard. Using the Windows key in combination with another key allows the user to perform common tasks more quickly. For example, pressing the Windows key + E opens Windows Explorer. For a full list of Windows key shortcuts, see the Windows shortcut keys page.
Tip: Users who are familiar with Macs can relate this key to the Apple command key.

Password protecting Microsoft Word and Excel documents


Tip: Before password protecting any document, you may want to create a backup of the non-password protected file in case you forget the password in the future.

Users who are creating a Microsoft Word or Microsoft Excel document that they want to keep confidential or to only be viewed by people who should be viewing it may want to enable a Microsoft Word or Excel password on the file to help protect the contents of the file. Below are the steps required for creating a Microsoft Word or Excel document with a password.
  1. Open Microsoft Word or Microsoft Excel and the document you want to password protect.
  2. Click File
  3. Click Save As
  4. In the Save As window, click the Tools option in the upper right-hand side of the window.
  5. From the Tools drop-down menu, select General Options
  6. This opens a Save window that allows you to specify a password used to open the file or modify the file.
Password to open - Entering a password for this option makes the file only readable to the users who know the password.
Password to modify - Entering a password for this option allows you to view the file but only edit and save the file if they know the password. Keep in mind, however, that a user could open the file, copy the contents of the file to another file, and modify and create their own document.

How do I password protect my files and folders in Windows?


Tip: Before password protecting any document, you may want to create a backup of the non-password protected files and folder in case you forget the password in the future.



The majority of Microsoft Windows operating systems do not come with a method of password protecting your sensitive files and folders. If you're using Microsoft Windows 3.x, Windows 95, or Windows 98, you need to download or purchase a third-party program to password protect your files and folders in Windows; skip down to the other security solutions section if you're using one of these operating systems.

Things to remember when encrypting or password protecting files and folders

Microsoft Windows XP professional users

The steps below for encrypting the files on Windows XP Professional applies to users who are using a computer that has different accounts. If you are using a single account, see the other security solutions section.
  1. Select the file or folder you want to encrypt.
  2. Right-click the file or folder and click Properties.
  3. Click the Advanced button.
  4. Check "Encrypt contents to secure data" option.
  5. Click Apply and then Ok.
Encrypt contents to secure data is grayed out
This will be grayed out if you're using the home edition of Microsoft Windows XP. See the steps below for securing the contents of your folders in Windows XP home.
Show "Encrypt" on the context menu
The newest version of TweakUI also enables you to show the Encrypt option in the context menu. To do this, follow the steps below.
  1. Open TweakUI.
  2. In the TweakUI window, select Explorer
  3. In the right side of the window under Settings, locate Show 'Encrypt' on context menu and check the box. This option should be below Prefix 'shortcut to' on new shortcuts and above Show 'View workgroup computers' in NetPlaces.
  • I'm missing Show "Encrypt" on the context menu in TweakUI.

Microsoft Windows XP home users

  1. Select the file or folder you want to encrypt.
  2. Right-click the file or folder and click Properties.
  3. Click the Sharing tab.
  4. Check the box Make this folder private
  5. Click Apply and then Ok.
Make this folder private is grayed out
In order for this option to work in Microsoft Windows XP home you must meet the below requirements.
  1. The hard drive must be formatted in NTFS and not FAT32 File System.
  2. The folder you're attempting to encrypt must be in your own personal folder. For example, if your name is bob, you must be encrypting a folder that is or that is contained within the below folder:

    C:\Documents and Settings\Bob\

    You cannot encrypt any folders outside of this folder. If you want to encrypt outside this folder, see the below other security solutions.

Microsoft Windows Vista/7/8 users

Unfortunately, Windows Vista, Windows 7, and Windows 8 do not provide any features for password protecting files or folders. You need to use a third-party software program to accomplish this.
If you want to encrypt a file or folder, this can be done by following these steps:
  1. Select the file or folder you want to encrypt.
  2. Right-click the file or folder and click Properties.
  3. Click the Advanced button.
  4. Check "Encrypt contents to secure data" option.
  5. Click Apply and then Ok.

Other security solutions for protecting your files and folders in Windows

File and folders not frequently used
If you need to password protect files or folders that you do not frequently use, one of the simplest ways is to compress the folder and files with a compression utility and password protect the compressed file. However, each time you want to work with or modify the files, you need to uncompress the files using the password.
Windows ME and Windows XP users - Windows ME and Windows XP come with their own compression utility. This utility can also be used to compress and password protect files.
Windows Vista and Windows 7 users - Windows Vista and Windows 7 also include a compression utility. However, password protection for the compressed files is not possible without the use of a third-party software program.
Tip: When a file is compressed, users can still view a listing of the files in the compressed file. If you want both your file names and the contents to be hidden, move all the files into a single folder and password protect that folder.  
File and folders frequently used or accessed
If you need to password protect or encrypt data you frequently use, you need to install a third-party program that allows you to protect your files and folders. Below are some free and commercial solutions.
  • 7-Zip - A free file and folder zipping utility, which also includes the ability to password protect zipped files and folders.
  • AxCrypt - An excellent free encryption utility that enables users to encrypt all files within a folder and not allow those files to be viewed unless a passphrase (password) is known.
  • Folder Guard - A commercial version of a password protection software that enables you to password protect files, folders, and other Windows resources.
  • Protected Folder- For a small fee, it's an excellent software program that enables you to password protect folders.

Things to remember when encrypting or password protecting files and folders

  1. There is no such thing as a 100% protected file. There are numerous tools, utilities, and instructions for how to break encryption and passwords on files. However, the protection methods listed above will protect your files from the majority of users who may encounter them. If you are working with really sensitive data, we suggest a commercial product for protecting your files and data.
  2. Even though a file or folder may be password protected, it still can be deleted (unless the program supports the ability to protect files from being deleted). Always remember to backup all your files, even those protected by passwords.
  3. If you forget the password, unless you're willing to spend the time attempting to break it or pay someone else to break the password, all the data in the file or folder will be lost. Thus, it is important to backup a copy of the non-password protected files or folders, just in case.

Microsoft DOS debug command


About debug

Debug is a method of looking at portions of your computer and writing assembly code to perform certain tasks on your computer.
MS-DOS 2.x - 4.x uses debug.com
MS-DOS 5.x and above uses debug.exe

All Versions of MS-DOS
Windows 95
Windows 98
Windows ME
Windows NT
Windows 2000
Windows XP

Syntax

How to find the BIOS Type, version, and date

View BIOS information at POST

The first way is by restarting your computer. When the initial load (also called POST) screen is displayed, the BIOS Type and version is also displayed. If the load screen is displayed for only a few seconds, you may be able to press the Pause/Break key on your keyboard to stop the computer at that screen, long enough for you to find the BIOS information.
The BIOS information is typically found at or near the top of the POST screen.
Computer BIOS information, version, and date
Also, you will see information on what hard drive(s) and CD/DVD drives are installed in your computer.
Tip: It is also at this screen where you could access the BIOS Setup itself for more information on the hardware on your computer and the various BIOS and hardware settings currently available.
To help with load times or to display a company logo this screen may not be viewable. If this is the case try the below alternate resolutions.

Through Windows System Information

The BIOS information is also shown through the Windows System Information. To open this tool click START, Programs, Accessories, System Tools, and then System Information. If you're running Windows Vista or Windows 7, type System Information in the Start search box.
This opens the System Information window, displaying information about your computer, including the type of BIOS you have and the version, under the System Summary section. As can be seen in the picture below, this computer has a DELL BIOS version 1.0.0 with a Date of 11/5/2008.
Windows System Information

In the Windows Registry

You can also find BIOS information in the Windows System Registry. This area is a bit more dangerous to navigate around, as you can change values that could affect how Windows operates. So be careful if you choose to use this option to view your BIOS information.
To access the System Registry, click START and in the Run or Search box type regedit in the text field and press enter. In the Windows Registry navigate to the below registry directory.
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System
Find the subkeys SystemBiosDate and SystemBiosVersion to see the BIOS and version for your motherboard. As can be seen in the picture below, the BIOS date and version are shown in these two keys.
BIOS in the Windows Registry

Finding BIOS date through debug routine

Earlier computers that do not have access to the above tools can also use the MS-DOS and Windows command line debug command to view the BIOS date, as shown below.
At the C:\> Type the below commands.
 debug
- d FFFF:5 L 8
After typing the above command, you should receive a string similar to the example below.
FFFF:0000 30 34 2F-33 30 2F 39 38 4/30/98
The 4/30/98 would be the date of your computer BIOS.

No power or computer does not turn on


Notice: If the computer is turning on but is not posting (beeping) or giving any picture on the display, see POST troubleshooting. This page also does not cover a laptop computer that is not turning on.
If you are uncertain if the computer is turning on or not, this can be checked by locating any fans in the computer or visible from the outside of the computer. If these fans are spinning, the computer is receiving power and this document may not apply to your issue.

Connections not connected properly

Computer power cordVerify that the power connection is connected properly to the wall and the back of the computer. If the connections appear to be connected properly, disconnect, and reconnection both ends of the power cord to make sure the cable is not loose.
If you have a power strip (surge protector) or switch used to turn everything on at once, temporarily disconnect the computer from that switch and connect that cable directly to the wall. This helps verify that the strip or switch is not bad.
Verify that the outlet works by connecting a different component to that switch.

Third-party hardware

If additional hardware has been recently added to the computer it is recommend that you temporarily disconnect that device or devices from the computer to verify they are not preventing your computer from turning on.
Note: If the computer was working fine before you added the new hardware, removing the third-party hardware did not resolve the issue, and the computer is not beeping but is turning on, see the POST troubleshooting steps.

Bad power cable

Verify that the cable supplying your computer is not bad or damaged by using another power cable. If you have a standard CRT monitor, this cable can be used in place of the computer power cable.
If you have a portable computer or laptop, when the cables are plugged into the laptop you should see a power light or battery charge light. If this light is seen, this is a good indication that the power cable is good.

Incorrect power supply

If you are building your own computer or if the computer has never turned on since you purchased it, you may have a power supply that does not supply enough power or the incorrect power supply. Verify your power supply meets the requirements of your motherboard and processor.
  • How do I determine how big my power supply is?
  • How big of a computer power supply should I get?

Bad battery

If your computer is a laptop or portable computer that utilizes a battery for mobility it may be causing your issue.
  • If your computer powers on when the cable is connected to the portable computer but not when it is disconnected, we recommend you purchase a new battery.
  • If your computer does not power on when the battery is connected and when the power cable or charger cable is connected, try removing the battery and seeing if the computer can power on with only the power cable connected. If no power is still received, skip to the final section.

Bad power supply, power button, power board, or inverter

If, after following the above sections, your computer still receives no power, it is likely that a hardware component in the computer has failed. It is most likely that the power supply has failed. If you do not plan on replacing the power supply yourself or if you have a portable computer, we recommend having the computer serviced by your computer manufacturer or a local computer repair shop.
If you have a desktop computer and plan on trying to repair the computer yourself, we recommend you replace the components in your computer in the below order.
  1. First open the computer and verify the power connections. Also, consider disconnecting the main power cable and reconnecting the power cable to make sure it has not become loose. Also, verify the power button cable is correctly connected to the Motherboard.
  2. Replace the power supply with a new power supply.
  3. Replace the motherboard.

My computer is running slow what steps can I do to fix it?

Slow computer 
 
Tip: This page only covers an overall slow computer and not a computer that has a slow boot up or slow Internet.
Below are steps for Microsoft Windows users that can help speed up the computer or determine why the computer is running slow.

Reboot

If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below.

Background programs

One of the most common reasons for a slow computer are programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.
Tip: To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resmon to get a better understanding of how your computer is being used.
If you have an antivirus scanner on the computer, spyware protection program, or another security utility, make sure it is not scanning your computer in the background. If a scan is in progress, it can decrease the overall performance of your computer.

Delete temp files

As a computer runs programs, accesses web pages, and is being used in general, temporary files are being stored on the hard drive. Deleting these temp files can help improve computer performance.
First, we suggest using the Windows Disk Cleanup utility to delete temporary files and other files no longer needed on the computer.
Temporary folderUnfortunately, the Disk Cleanup may not delete all of the files in the temp directory. Therefore, we also suggest deleting temporary files manually by opening the Start menu and enter %temp% in the Search field (in Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field). Press Enter and a Temp folder should open. You can delete all files found in this folder and if any files are in use they can be skipped.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size, as well as room for temporary files.
  • Determining available hard drive space.
  • Regaining computer hard drive space.

Bad, corrupted or fragmented hard drive

  • Run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer's hard drive.
  • Run Defrag to help ensure that data is arranged in the best possible order.
  • Use other software tools to test the hard drive for any errors by looking at the SMART of the drive.

Scan for malware

Today, spyware and other malware is a big cause of many computer problems, including a slow computer. Even if an antivirus scanner is installed on the computer, we recommend running a malware scan on the computer. Use the free version of Malwarebytes to scan your computer for malware.

Scan for viruses

If your computer is infected with one or more viruses, this can cause your computer to run slow. If your computer does not have an antivirus program installed, you can run Trend Micro's free Housecall online utility to check for viruses on your computer, as well as remove them. It is also recommended that you install an antivirus program for active protection against viruses.

Hardware conflicts

  • Verify that the Device Manager has no conflicts. If any exist, resolve these issues as they could be the cause of your problem.

Update Windows

  • Make sure you have all the latest Windows updates installed on the computer.
  • If you are on the Internet when your computer is slow, make sure all browser plugins are up-to-date.

Update your drivers

Make sure you have got the latest drivers for your computer, especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues, including slow performance.

Reboot computer again

If you have done any of the above steps but your computer is still acting slow try rebooting the computer again at this point.

Memory upgrade

If you have had your computer for more than two years, you may need more memory. Today, we suggest computers have a minimum of 1GB of memory (RAM) for 32-bit system and 2GB for a 64-bit system. By having enough memory for programs to run within memory, your computer will not need to swap information stored within memory to the swap file. If your computer hard drive light is constantly active, its a good indication that your computer is swapping information between your memory and hard drive because of the lack of space in memory.
  • Determining how much RAM is installed and available.
  • How much memory or RAM should my computer have?
  • What type of computer memory to use in a memory upgrade?

Hard drive upgrade

One of the biggest bottlenecks of a computer is the hard disk drive. For anyone with a slow computer or just looking for something to upgrade in the computer to improve overall system performance, upgrading from a traditional hard drive to a Solid State Drive (SSD) will significantly improve the overall system performance.

Run registry cleaner

We normally do not recommend registry cleaners. However, if you have followed all of the above steps and your computer is still slow, try running a registry cleaner on the computer.

Computer or processor is overheating

Make sure your computer and processor is not overheating. Excessive heat can cause a significant decrease in computer performance because most processors automatically reduce the speed of the processor to help compensate for the heat related issues.
  • What temperature should my processor be running at?
Dust, dirt, and hair can also constrict proper air flow inside your computer, which can cause a computer to overheat. Make sure your computer case is clean and fans are not obstructed.
  • Steps on cleaning your computer.

Erase computer and start over

If none of the above solutions resolve your issues, another option is to either reinstall Windows or erase everything and then start over.
Erasing everything and starting over can increase performance by getting rid of old software or drivers that may be on the computer and causing the computer to be slow. Installing a fresh copy of Windows, software programs, and the latest drivers help verify there is no software related issues causing your computer to be slow.

Hardware issues

Finally, if your computer continues to be slower than normal after going over each of the above recommendations (including erasing and starting over), it's possible that your computer is experiencing a more serious hardware related issue such as a failing component in the computer. This could be a failing or bad hard drive, CPU, RAM, motherboard, or other component.

Old computer

If your computer is older than five years, the age of the computer could be the cause of the slow performance. Computers advance in technology and capabilities and newer, more advanced software programs come out to run properly on the new computers. Older computers are not able to run the new programs as well, which can cause them to slow down. If your computer is older than five years, we suggest purchasing a new computer or accept that, if all the above options do not work to speed up your computer, it will just run slower than a newer computer.

My laptop mouse touchpad is not working

When the touchpad stops working, there are a few things you can do to try and fix it or work around the issue.
Tip: Since some of the settings do require you to navigate the mouse cursor for troubleshooting purposes use the Trackpoint, PS/2, or USB mouse a temporary fix. If you cannot get the mouse to work see our navigating Windows with the keyboard page for tips on how to use the keyboard to navigate in Windows.

Other USB device

Some USB and PS/2 devices, especially any USB input device (including a computer mouse), can disable the touchpad. As a troubleshooting step, turn off the computer, disconnect all USB devices, then start the computer again to make sure no other device is disabling the touchpad. If this fixes your problem, but the touchpad is disabled again, the next time you connect the device, check your touchpad software settings for a setting that can prevent this from happening.

Check mouse settings

First, in the Windows Control Panel, access the mouse settings and verify the touchpad is enabled. Also, you can adjust the sensitivity of the touchpad to work best for your fingers. Check these settings to make sure something was not disabled or adjusted to cause the touchpad to not work.

Check Device Manager

Second, open the Device Manager and check through the device list and find the touchpad. Check to see that it is enabled. If disabled, re-enable it and test the touchpad. If it is already enabled, change it to disabled, then re-enable it again. Sometimes toggling this setting can kick-start the touchpad into working again.
If there are any yellow exclamation marks, red X's or "Other devices" in Device Manager, any of these errors can indicate there is a problem with hardware in your computer that may be causing the touchpad problems.
  • Identifying problems in Windows Device Manager.

Check CMOS (BIOS) setup

Make sure the touchpad has not been disabled in the CMOS (BIOS) setup. In the setup, check the hardware device settings and see if the touchpad is enabled or disabled. If disabled, re-enable it, restart the laptop, and test the touchpad.
  • How to enter the BIOS or CMOS setup.

Software driver issues

If the above options do not fix the problem, the software driver for the touchpad may be corrupted or not updated enough to work correctly. Visit the laptop manufacturer's website and download the most current touchpad driver for your specific laptop model. Install the driver, restart the laptop, and test the touchpad to see if it works.

Hardware defect

Lastly, if the touchpad still is not working correctly or at all, you may need to take it to a computer repair shop and have it fixed. It could require replacement of the touchpad itself or another component in the laptop. If you cannot repair the touchpad, connect and use an external mouse as a workaround.

How do I get out of Safe Mode?

From Windows Safe Mode, click Start, Shutdown, and restart the computer. This will start the computer automatically back into Normal Mode.
Note: Many users believe that they are still in Safe Mode because the colors or video may not look correct. Unless in the corners of the screen it says "Safe Mode", you are not in Safe Mode. For information on how to setup your video card resolution, see document CH000190.
If you are rebooting the computer and it is rebooting back into Safe Mode (it does say "Safe Mode" in each of the corners), it is likely another problem exists with Windows preventing it from loading into Normal Windows. We recommend you see the basic troubleshooting section for additional ideas that may help to resolve your issue.

Which Safe Mode option should I choose?

Users who are running later versions of Windows will get different options for different versions of Safe Mode. For example, you may have options for "Safe Mode", "Safe Mode with Networking", and "Safe Mode with Command Prompt." Below is a brief description of each of these different modes.
Safe Mode
The basic Safe Mode option is usually what most users will want to choose when troubleshooting their computer. This is the most basic Safe Mode option and has no additional support.
Safe Mode with Networking
For users needing access to the Internet or the network they're connected to while in Safe Mode, users may want to choose this option. This mode is helpful for when you need to be in Safe Mode to troubleshoot, but also need access to the Internet so you can get updates, drivers, or other files to help troubleshoot your issue.
Safe Mode with Command Prompt
This Safe Mode allows you to have access to the command line (MS-DOS prompt).
