Yes, I am using Windows 7 on my laptop, installs like a dream and have had no problems at all. Whats quite amusing though is its not really Windows 7, its infact Windows 6.1. Its as solid as XP, works on my 3 year old laptop beautifully. What I get though is a little odd. When I launch CCleaner from the desktop icon, it starts minimized even though the icon is set to start normal. Start it from the Program Files menu, and it starts normally.. Very odd !! All other desktop icons work fine ..
