Sorry if this is in the wrong section, staff, feel free to move it.
My PC has been lagging quite a bit lately. I decided it was time to get everything sorted. I deleted all of my unwanted files, uninstalled lots of programs which were lagging my PC, defragged my hard drive and then I installed CCleaner. I'd heard some good reviews about it. After I ran the program with cleaned up all of my files, I restarted my PC and now it is saying that my Windows XP is not genuine.
It was a completely legitimate version of Windows (Windows XP Pro SP3 if it matters) but now it's 'non genuine'. Surely CCleaner has deleted a file or edited my registry and messed up my license.
Help!
