This is from the www.webtree.ca:

"Build an XP-SP2 Recovery Disc
Slipstreaming Service Pack 2
Here's the problem: Once you upgrade to SP2, you won't ever be able to
install the original version of Windows XP over it; you have thus rendered
the ancient practice of reinstalling the operating system impossible."

What happens if I have to reformat and reinstall my OS? All I have is the
CDs from HP with XP-Home/SP1. Should I uninstall SP2 to prevent that from
happening?
