BleepingComputer.com: Windows Vista System Recovery

Hi i'm having some troube wth my computer and was wondering if anyone could help. i bought my computer with windows XP installed and have since installed vista as an upgrade. i am haiving some serious problems with viruses ad thr things, if i were to do a system recovery, would it go back to XP or would it stay with vista. Thanks

It depends on which System Recovery option you're choosing. Could you describe how to get to the option that you're using?

When the PC starts up, it comes up with a screen with some options; including system restore. when selected it gives me the option of destuctive restore and windows system restore. i was going to do the destructive restore. thankyou

A destructive system recovery will erase your hard drive and put back the OS that the restore partition contains. Most likely, when you upgraded to Windows Vista you didn't upgrade the restore partition - so you'll most likely end up with Windows XP if you use the destructive recovery option.

if i do the destructive recovery and it does go back to XP, will i be able to install vista on it again using the same disc

Yes, you should be able to - but it all depends on the upgrade that you used and the associated product key.
