Fix XP Power Toys are missing!

| Friday, March 27, 2009
Some Windows XP Power Toys released in a previous version are no longer in the present version. Usually, these were items with which some users reported having problems (though in some cases I’m not aware of any reported problems). While it is prudent to assume that these were pulled from the current set for good cause — due to some problem — it is also true that many computers had no problems with these. This post provide further information and windows operating system support tips for fix Windows XP power toys missing Error.

Before installing new versions of the XP Power Toys, you have to uninstall the old ones. If you already have one or more of the following items installed and you uninstall it, you will not find a replacement version in the current Power Toys release, so you will not be able to reinstall it unless you have the original install files saved somewhere. You have to make your own decision whether or not to continue running these utilities that Microsoft pulled from circulation — I’m just giving you information about the situation (and personally declining to uninstall the withdrawn Background Switcher!).

Background Switcher - (New, December 2001. Withdrawn January 2002.) This one allows your desktop background to periodically change. After you install it, go to Desktop Properties (right-click on an empty part of the desktop) and click on the new Slide Show tab. Select the folder holding the images you want to use, choose whether they should be rotated randomly or sequentially, and pick how often you want them to change.

Faster User Switcher - (Withdrawn April 2002.) “With Fast User Switching enabled on Windows XP, this PowerToy allows you to switch users without having to use the logon screen.” To enable it once it’s installed, see Control Panel | User Accounts | Change the way users log on or off | Use Fast User Switching. You then can use Win+Q to toggle between users. (The Win+L function remains available also and, frankly, I prefer it.) To learn about restrictions to this function, search under “Fast User Switching” in Help & Support.

ISO Image Burner - (New, December 2001. Withdrawn January 2002.) As mentioned above, I’m not the one to ask about this; but a lot of people have been waiting for this one! Burn ISO images to a CD-ROM burner. Since this one has been withdrawn, a very popular recommendation is Alex Feinman’s ISO recorder, available here .

Shell Media Player - (New, December 2001. Withdrawn January 2002.) Play music from the desktop taskbar. After executing the install file, right click your desktop taskbar, click on Toolbars, and click Audio Player. You should see four buttons, one green and three blue. If you do not see these, then you need to resize the Audio Player portion of the taskbar. (You may need to unlock the taskbar to do this: Right-click on it to get this option.) Click the up-pointing button, load your playlist, and you’re off!

Change the System/Boot Drive Letter

| Tuesday, March 17, 2009
Important This post, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows

1. Make a full system backup of the computer and system state.
2. Log on as an Administrator.
3. Start Regedt32.exe.
4. Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
5. Click MountedDevices.
6. On the Security menu, click Permissions.
7. Verify that Administrators have full control. Change this back when you are finished with these steps.
8. Quit Regedt32.exe, and then start Regedit.exe.
9. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
10. Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
11. Right-click \DosDevices\C:, and then click Rename.

Note You must use Regedit instead of Regedt32 to rename this registry key.
12. Rename it to an unused drive letter "\DosDevices\Z:".

This frees up drive letter C.
13. Find the drive letter you want changed. Look for "\DosDevices\D:".
14. Right-click \DosDevices\D:, and then click Rename.
15. Rename it to the appropriate (new) drive letter "\DosDevices\C:".
16. Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
17. Quit Regedit, and then start Regedt32.
18. Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
19. Restart the computer.

Note: If these steps not sufficient for you contact to computer support technician to take technical support.

Fix Invalid System Disk Error

| Wednesday, March 4, 2009
You may also receive this error message when you start your computer by using a Windows Startup disk, or you may receive the following error message:

This version of Windows does not run on DOS 7.0 or earlier.

This issue can be caused by any of the following conditions:

* Your computer may be infected with a boot-sector virus such as the AntiCMOS.A virus.
* Your computer is running an anti-virus program.
* Your computer is using hard disk management software (such as Disk Manager, EZ-Drive, or DrivePro) for hard disk geometry translation. These tools provide support for large hard disks (more than 1024 cylinders) when your computer's Basic Input/Output System (BIOS) does not support large hard disks.
* Windows Setup was unable to copy the system files to the hard disk.
* Security software has disabled access to drive C.

To fix this issue use one of the following

Computer Is Infected with a Virus
Use an anti-virus program to detect and remove the virus, and then reinstall Windows. Boot-sector viruses infect computers by copying information either to the boot sector on a floppy disk or the partition table on a hard disk. During startup, the virus is loaded into memory. Once in memory, the virus typically infects any non-infected disks that your computer is connected to.

Computer Is Running Anti-Virus Software
Start your computer by using the Windows Startup disk you created during Windows Setup, and then use the sys command from the Windows Startup disk to restore the system files to the hard disk.

Some computers use built-in anti-virus software that must be disabled in the computer's BIOS. For information about how to change settings in the BIOS, view the computer's documentation or contact the manufacturer of your computer.

Computer Is Using Disk Management Software
In some cases, Windows may not properly detect that you are using disk management software and may overwrite the master boot record (MBR) information. Refer to the documentation for the disk management software you are using for information about restoring the MBR.

Also, check the Setuplog.txt file for the following statement:

FSLog: BIOS Heads=:64:, BootPart Heads=:64:
The preceding number (64 in this example) may vary from computer to computer. If these two numbers are different, replace the system files on your hard disk according to the instructions in the following "Reinstall the Windows System Files" section. For additional information about how to determine if your computer is using a drive overlay program

Reinstall the Windows System Files
WARNING: If you are using Disk Manager or any other disk drive overlay program on a hard disk, make sure that the overlay driver is loaded before you use the sys command on that hard disk. If the overlay driver is not loaded and you use the sys command on the hard disk, the drive may not be recognized as being partitioned by the disk drive overlay program and you could experience loss of data or an inability to boot from the drive.

Although you can use the sys command with Ontrack Disk Manager and later versions of MicroHouse EZ-Drive (or EZ-Max) after the overlay driver is loaded, earlier versions such as EZ-Drive 2.01s require that operating system files be copied to the overlay installation disk and installed by the overlay utility. In such cases, the overlay may be damaged if you use the sys command on the hard disk.

1. Start your computer by using the Windows 95 or Windows 98 Startup disk.
2. At the command prompt, type the following commands, pressing ENTER after each command:

c:
cd\windows\command
attrib c:\msdos.sys -s -h -r
copy c:\msdos.sys c:\msdos.xxx
a:
sys c:
attrib c:\msdos.sys -s -h -r
del c:\msdos.sys
copy c:\msdos.xxx c:\msdos.sys
attrib c:\msdos.sys +s +h +r
3. Remove the Windows Startup disk, and then restart the computer.

Security Software Enabled
Some third-party programs prevent (lock) access to hard disks in your computer. If this software is installed, contact the manufacturer about how to remove this software and safely restart Windows 98 Setup. For additional information about Windows Setup and troubleshooting
