Hello, i have had this problem aswell after installing Steam on window 7 64bit. Once i open up steam this pop up "Running Steam in Windows compatibility mode is not recommended. Please remove any Windows compatibility settings for all users under file properties for Steam.exe and restart Steam. Press 'Cancel' to premanently ignore this warning and continue." I tried the both you have posted by going into both the registery but i couldnt find steam.exe. I then hit cancal to permantly ignore this warnining and it opened up steam without any problem. Im just wondering if this would damage the system in any way? Thanks!
