Thank you bigmuscle, it's work. Note: i don't want uninstall the AG8, work fine for me, thanks. I just tried understanding the problem to help another users. (The installer can't set the default options while uninstall the AG8?)

Did you make sure to set the current theme back to default before uninstalling? Since AG is gone the system won't accept the custom theme, resulting in a black screen. If that's the case then you can use any rescue disc to access registry, navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ThemeManager and set the DllName back to its default value, which is "%SystemRoot%\resources\themes\Aero\Aero.msstyles" (no quote), reboot and voilà. Thanks, but did not help. Theme default, dllname default, AG uninstall, Win not starrted. Maybe because by an reg key from older version? I see few key after uninstall, but i don't know which is win-key in dwm section.

Hi, I read on another forum abouth problem after uninstall AG(1.1, 1.2). Win8 won't boot, just flashing the black screen instead login or login screen. I checked this and also i had same problem. Only way was the system restore. Any idea?
