Installing .NET 4 on an updated Windows XP machine (sometimes?) results in breaking Windows Update. When .NET 4 is installed, Windows Update consistently fails with error code 0x8024402F. Removal of the .NET 4 installation returns Windows update to work.

Try this:

go to services and disable windows update
delete C:\windows\SoftwareDistribution
turn "windows update" back on
Run windows update
I had success solving this issue on an XP machine by ensuring that the regional and time settings where correct
