How do i Reinstall Windows ?

[tesco]

Will it f' up certain programs that have data in the registry?

I've done a repair install on my computer once or twice and a few times on friend's computers and i can't remember having any problems with any programs (it's not deleting the registry entries of programs, just the XP ones).

Thanks Rossco I might try that on the one I have been having problems with.
