Although it is not recommended, you would need an older pre-SP2 Dell
Reinstallation CD and then proceed with a repair install. Please be aware
that you will sacrifice any Dell support for Windows XP in the future since
you are altering the O/S with an older O/S.

Also, you cannot use a Windows XP "retail version" CD with the Dell Product
Key.
The trick is finding an older pre-SP2 Dell Reinstallation CD to use for the
repair procedure.

Hi

Is there anyway to bring down an sp2 machine to sp1? Possibly by
reinstalling from xp sp1 cd on top of a sp2 installation? Ideally I would
like to retain all apps during the process if possible.

Thanks
