I do not know what many users against Windows Vista ?? !! Sure, it was annoying at the beginning -> User Account Control ...
I have Win Vista Ultimate 64-bit (OEM) now good 1-1 / 2 years in operation (Intel Core 2 Quad, 4.0 GB RAM, GeForce GTX 260, 1.25 TB HDD) and can not mekern.
The system runs without crashes, hangers etc. Especially DreamScene has it done to me ...;)
Did Win 7 RC running on my test notebook. The differences are very small in my eyes. Who Vista given a chance, know what I mean! ;)
Will not migrate to Windows 7 - very earliest Summer 2010 ...
