A while back my brother bought a computer powered by Linspire however we couldnt get various hardware things to work with it at the time. So he decided to throw on Windows XP instead. This caused a great hit to the performance but regardless it worked for what it was needed for.

Fast forward and I have found this computer and want to check if Linspire is still on it or if they dropped it completly and replaced it with XP. How do I do that?

Is it possible to check if linspire is still comewhere within the computer and if so can I drop XP all together and get it back into its origional state as a Linspire computer? Its a decent computer and ran quite well while running Linspre but once xp was put on it now has very very poor performance.
