7H works just fine with Windows 10. There is a 3rd party component of 7H being used called EasyHook which has a bug on the newest updates of Windows 10. This bug has been reported to the EasyHook developers and hopefully they find a fix soon. However, in the meantime, 7H still works just fine if you set your FF7.EXE's 640x480 compatibility flag. The next version of 7H will set this for you automatically (or if an EasyHook fix is released, will include that instead).
