Vista - Issues running games from various manufacturers

I am using Vista RTM and I am trying to run games such as Quake 4,
Battlefield 2142, and Call of Duty 2, all of which are by different
companies, and none of the will run. I get an error that tells me to insert
the correct CD/DVD. I have upgraded the firmware on my drives and get the
same issue. I know that they work because they were working under RC2. There
is also nothing wrong with the drive or the CD's because they will play in
other machines perfectly fine. What am I missing here?

Patches from the manufacturers. Anno 1701 ran on Vista x64 for me until
rtm. Now that driver signing is enforced it won't run because the Copy
Protection driver is unsigned. Civilization III complete ran also but now
stops with a font missing error. Different issues to be sure. Probably due
to workarounds being removed from the final code.

I figured out what was wrong. I had UAC turned off. Once I uninstalled the
games, turned UAC on and reinstalled the games everything worked fine. I was
then able to go in and turn UAC off and everything still worked fine.
