The stealth Update that Microsoft released back in August isn’t quite as harmless as the company claims.

Ever since the Redmond company’s recent download of new support files for Windows Update, users of XP’s repair function have been unable to install the latest 80 patches from Microsoft.

Repaired installations of XP can’t be updated

The trouble occurs when users reinstall XP’s system files using the repair capability found on genuine XP CD-ROMs. (The feature is not present on "Restore CDs.") The repair option, which is typically employed when XP for some reason becomes unbootable, rolls many aspects of XP back to a pristine state. It wipes out many updates and patches and sets Internet Explorer back to the version that originally shipped with the operating system.

(After a repair install of XP, which resets the operating system to its original state, Windows Update can’t install the 80 most-recent patches from Microsoft.)

Most ordinary Windows users might never attempt a repair install, but the problem will affect many administrators who must repair Windows frequently. Anyone who runs XP’s repair function will find that isolating the cause of the failed updates is not a simple matter.

Manually registering files solves the problem

If you find that Windows Update refuses to install most patches, you can register its missing DLLs yourself. This can be accomplished by manually entering seven commands (shown in Step 2, below) at a command prompt. If you need to run the fix on multiple machines, it’s easiest to use a batch file, as Steps 1 through 5 explain:
Step 1. Open Notepad (or any text editor).
Step 2. Copy and paste the following command lines into the Notepad window (the /s switch runs the commands silently, freeing you from having to press Enter after each line):

regsvr32 /s wuapi.dll

regsvr32 /s wuaueng1.dll 

regsvr32 /s wuaueng.dll 

regsvr32 /s wucltui.dll 

regsvr32 /s wups2.dll 

regsvr32 /s wups.dll 

regsvr32 /s wuweb.dll

Step 3. Save the file to your desktop, using a .bat or .cmd extension.

Step 4. Double-click the icon of the .bat or .cmd file.

Step 5. A command window will open, run the commands, and then close.
