Installed RC1 yesterday. Winrar = OK. Just as in XP. Nero 7 = OK. Custom install, Nero Express and Nero Burning ROM only. CounterStrike 1.6 = OK. Slight improvement over XP. CounterStrike Source = OK. Didn't notice any difference over XP. Office 2003 = OK. Opens up more quickly than in XP. ACDSee 8 Pro = OK. Custom install, left out "Device Detection". Although presented with a number of pop-ups regarding compatibility, it runs exactly as it does in XP. Total Commander = OK. Same as in XP. Technisat Utility = NOT OK. It checks for WMP 9 or higher but doesn't recognise version 11, install fails. Technisat, please read and do something about it!
