It is now safe to power off the system

Today I learnt from @Libre盖子 (Tom Li) that Windows still has the ability to not turn off the power after a system shutdown. This is so nostalgic! I haven’t seen this screen since the beginning of this century.

According to him, you can enable Group Policy Computer Policy > Administrative Template > System > Do not turn off system power after a Windows system shutdown has occurred. After this, if you shut Windows down, you will see the ‘it is now safe to power off the system’ screen as shown below.

Note that if you do not see this screen after shutdown, then you might have hibernated instead. Many computers support fast start-up and have this feature enabled, which causes the ‘Shut down’ button on the Start screen to perform shutdown /sg /hybrid /t 0. This will use Restart Manager to save any apps that wish to reopen, log off all sessions, and put the system to hibernation. To perform a true shutdown, run shutdown /sg /t 0 or shutdown /s /t 0, depending on whether you want applications to restart the next time you log on.

Tom Li also gave a possible application. Read his Weibo for details. In memory of the pre-ACPI era, I have also produced two vector version of the screen in Windows 95 and Windows XP.

Why am I writing this in English? Because I have written too many entries in Chinese lately. Windows XP logo is available here. [Insert trademark disclaimer non-sense here.]
