For those of you who knows computers, I know this is going to sound like a stupid question, but is there a big difference?

The reason I am asking is because I need a reinstallation CD for Windows XP but only found the reinstallation CD for WMe, and my question is, can I use the WMe reinstallation CD instead on the Windows XP laptop? It’s my mom’s Dell laptop. If I cannot, can I get a copy of it from Dell or Microsoft if I tell them the ID that is on the laptop?

I utilized some registry cleaner softwares because my mom had some viruses in her laptop, and it probably erased something it shouldn’t have, it takes 20 minutes for the browser homepage to open, so I figured it would be easiest to use the reinstall CD. I would do the "undo" feature except there are no records for me to undo.

Thanks so much in advance to everyone!
