I did have some Problems with it.
1st of all for a long Time I could not find the “show Desktop” Button, until just yesterday I, by Accident, I found out it is that glassy Button at the right End of the task bar. Way to hide an important Function, MS.
Second, Win 7 (the 64 bit Version at least) prevents any non-certified Drivers from being loaded, and there is no Way to deactivate this function (not even by deactivating UAC) except to select a special boot Mode with F8 every time you start the System.
This was especially annoying since I use a Freeware Disk Encryption Programme, whose Drivers and Cypher Drivers are not certified by Microsoft (since that apparently costs a lot of Money). I had to install a special Bootloader that selects the special Bootmode automatically at System Boot.
Third, the Control Panel is unnecessarily convoluted, finding the Settings Page you want is a real Pain in the Arse, and there is no Way anymore to activate the Classic View.
But apart from that I had no Problems.
