Another point there, from 10 top companies, 5 use Linux on their servers, 3 use FreeBSD, and 2 use windows.
On servers, Linux rarely crashes, with Windows the server constantly reboots after a day or two.(this is proven)
Also, Vista was an overpriced OS which was crap.
UAC fucks everything up, you have to set permissions with checking, then confirmation to do that etc.
UAC ran on everything i ran at the beginning.(20 sec to run it)UAC turned off=2-3 secs.
MS should remove UAC, pure crap.
