I seriously doubt Conficker is on my PC, the computer is still rather new, and the reason for my reinstall of the beta was due to a problem with my moherboard that involved an RMA and after recieving a replacement I ran into problems booting up, shutting down and everything in between. As for windows Live messenger, it is completely compatable with XP, Vista and windows 7. The problem I'm experiencing seems to suggest a problem with permissions settings, so I'm going to do a reinstall and see if that fixes the problem, the difficulty may havce been run into during the installation. If that fixes my problems, you'll know.
After a reinstall (I love how fast it is) and a subsequent use of the key, windows recognized and validated my copy. If anyone is ever planning to install windows 7 beta on their computer, please make sure you have your computer hooked up to the internet for the entirety of the installation, as I had neglected to do this the first time I installed it and that is what most likely caused the problem.
