games run in Windows 7 64bit

I install windwos7 I load up my games with great trepidation but all the games that ran in Vista 64 also run in Windows 7 64.
They are:
Age of Empires (I should hope so MicroSoft released it)
Company of Heroes
Dangerous Waters
DCS Black Shark
Falcon Allied Force
Flashpoint Reistance
Guild Wars
MS Combat Flight Sim 3
MS Flight Sim X with Accelerator Pack
Oblivion
Star Wars: Empire at War
Lord of the Rings Online
The Witcher
Warcraft III
World in Conflict

some games that didn't run in Vista but run in windwos 7 now:
B17
Lock-On
Pacific Fighters
Silent Hunter 4
