Microsoft has confirmed the existence of a very serious problem which is occurring on some PCs after installing the latest update Windows 11: You can’t turn them off properly or make them go into hibernation mode. It can happen with those stuck at version 23H2 of the operating system and on which the KB5073455 package distributed in recent days, on the occasion of Patch Tuesday, has been installed.
Unable to turn off PC: Serious bug in Windows 11
In other words the computer restartsdespite the stop command. The software house is aware of the problem and has already promised to resolve it, but it will only happen with a future update. What to do for the moment?
There is a workaround, a temporary remedy for those who need turn off the PC. It consists of typing the command shutdown /s /t 0 via prompt. Here is the procedure to follow.
- Open the Start menu and type
cmdto open the command prompt; - type
shutdown /s /t 0and press Enter.
And for thehibernation? Nothing to do, Microsoft throws up its hands and admits that there are no alternative solutions available at the moment.
There is currently no workaround to enter hibernation mode. Until the problem is resolved, be sure to save all your work and turn off your device when you’re done, to prevent it from discharging instead of going into hibernation.
That is to say, on a laptop it is necessary force shutdown with the command seen previously, otherwise it will not automatically enter the energy saving mode, ending up quickly draining the battery.
What is causing the problem? It was spotted in Secure Launcha virtualization-based security service introduced with W10 and designed to protect the integrity of the computer during the startup phase. For further information, please refer to the official support (link at the bottom of the article).
Fortunately, the impact of the bug is expected to be quite limited. Version 23H2 is currently supported only in Enterprise and IoT editions. However, it is about theyet another disaster combined by the software house with the management of W11 updates, which to date remains the biggest Achilles heel of the operating system.
