Windows update issues post SP3 install

Yesterday I finished the re-install of my IBM ThinkPad T42 using the factory install disks. After completing the re-install, I diligently started the Windows Update process to make sure my laptop was up to date before pushing all my data back onto it.  After 2 patches, SP3 update was next and I let it do its thing for the next few hours and went to bed.  This morning I woke up to try and install a few optional updates and generally wrap the reload up and found I couldn’t install ANYTHING!

.NET 2.0 had a critical update that would take, nor would any of the optional hardware and software updates work.  Finally after googling around I found a post here that says:

This problem will not exist on the final version of SP3.

It can be fixed by running this command:

regsvr32 wups2.dll

Sure enough, after registering that dll file with the above command I am now able to apply all updates to the system.  Good for both future reference and for anyone googling around wondering why they can’t update their XP system anymore!
