Windows 2000 was the last reliable product from Microsoft.
Microsoft Product Activation will cause your computer to fail, like any other virus!
Microsoft Windows 7 (Vista 2.0) will not run Microsoft Visual Studio, just like Vista.
Windows 7 is Windows Vista 2.0. They did not fix the big problem you can not turn off the task scheduler service, the same as Vista. On a new Windows 7 machine, 1 day old and 33 tasks are in the schedule that I did not put there.
Windows 7 requires product activation. This is like showing your receipt at Wal-Mart every time you use the tooth brush that you bought months or years ago.
Do not buy anything from Microsoft until they get rid of product activation.
