实际上,并不是使屏幕全黑，而是让桌面背景(壁纸)变黑 Wallpaper and Background Get Auto Reset to Black Screen Every 60 Minutes
Customers found to be using non-genuine versions of Windows will receive a message during logon that their copy of Windows appears to be non-genuine and will be directed to the WGA Web site to learn more. Users who choose not to obtain a copy of genuine Windows will receive periodic reminders. Upon login, the desktop wallpaper will be replaced with a plain black background. The user may reset the background to a wallpaper or another background color, but every 60 minutes, the desktop will be reset to a plain black color until the copy of Windows passes validation. In addition, a persistent notification will appear in the lower right corner of the desktop. Regardless of genuine status, users will not be denied access to critical security updates. Users who have not validated their computers as genuine, however, will not be able to install many updates, including Windows Defender.
