Worked perfectly on my x64 VM, didn't have to change any settings from the last version, just edited the reg file and logged out and then logged in and working 100%, no noticeable lag, no random crashing when opening start menu (with SIB) as I was getting in all previous versions, only thing I have noticed so far is if you restart explorer (using a right click context shortcut) the whole screen is blurred for a second, I was just wondering though if you plan on making blur and rounded corners optional in your final release, I love that you have found a way to bring back all these features but personally I prefer no blur at all and have it disabled in Windows 7 on explorer windows anyway.
Also one other question, with that registry setting for rounded corners, is there any way to reverse that effect and make corners square in Windows 7?
Is there any possibility (i.e. registry key) to disable blur and leave transparency only in Windows 7? If yes, then this settings must work here too (and I just don't respect that settings), but no custom settings will be done in D3D...you can still set to D2D mode and set BlurDeviation to zero.
Rounded corners will stay as it is - just simple registry settings, nothing more, nothing less. And yes, it can be modified in Windows 7. Since it is only hooking of CreateRoundRectRgn which is called when window frame is created, then I guess my utility will work in Windows 7 too without any additional modifications (and aero glass won't be touched at all).
