I have been very pleased with my installation of windows 7. I upgraded from xp with a purchase of a new laptop, and have had zero problems getting anything and everything set up just the way I like it. My opinion might change if I try to dual boot a linux distro on here later and major problems arise though.
Ya i am agree with it that this is the best OS ever,it work with great feature and it work properly at the time of playing music videos or movies.
Windows 7 is a good OS and much much better as Vista. But for gaming, etc i am still using Windows XP because its more stable.
I am into win 7 recently and it is indeed fast.. though I never had any problem with xp and vista as well..
