After all the fun of trying to do a repair install of XP with yet another faulty disc, i finally got it installed correctly only to find another problem, I couldn`t install any Windows updates from Microsoft.
From the research i did to sort this out i found that this is a common problem after a repair install and there are fixes available. So i thought i`d post the fix on here to help out any PCHF members have the same problem.

First of all there are fixes available from Microsoft Support Updates are not installed successfully from Windows Update, from Microsoft Update, or by using Automatic Updates after you repair a Windows XP installation


Then there is the one that worked for me:-

1. Open Notepad

2. Copy and paste the following command lines into Notepad

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

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

4. Double-click the icon of the .bat file.

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

Hopefully this will save some of you the frustration that I went through
