It looks like enabling Hyper-V or WSL or even just enabling VBS's Memory Integrity disables Hybrid Sleep. This apparently happens on Windows 10 and on Windows 11.
I couldn't find official MS documentation that confirms this, but several internet posts say so too.

The easiest way to check this is with powercfg /a, which tells you if Hybrid Sleep is available. If you have any of the above features enabled, it probably says The hypervisor does not support this standby state. But if it works for you, please let me know.


This is frankly kinda shocking, because Memory Integrity is enabled by default now in Windows 11. So that means a lot of people lost the ability to use hybrid sleep. And they probably won't realize this, until they lose their work one day...
It's also weird, because both sleep and hibernation still work fine. It's just hybrid sleep that's affected.

Is this indeed how Windows behaves on every system and it's not dependent on any hardware/driver variables? And what is Microsoft thinking?
