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.
The next time you visit the Windows Update site, you should not have any problem installing the latest patches.
Pero antes de registrar dlls inecesariamente... trata de comentar más detalladamente los errores que te devuelve la página de Microsoft.
Un saludo y ya nos comentas.
