I found a lot of help here

I haven't been able to use the Windows Update site since installing SP2 on
my XP Home computer but could at least find out which updates I needed, then
search and install them individually. With this new development of the
"Genuine Validation Tool" I couldn't even find that to download. Luckily,
thanks to the above link, I found the Windows Catalog site where you can get
your downloads successfully again. Just go here

and you can stop tearing your hair out!
