Windows 10: Why is the "System Boot Time" in SystemInfo Wrong? Windows 11 Pro

Hi !!!I am running Windows 11 Pro Version 23H2, OS Build 22631 4602.I am developing an App that requires to know when was the last "System Boot Time".Practically every day, I turn on my PC in the morning, Windows starts as usual, keep my PC turned on during the day, and at the end of the day I click on Start then Shut Down.Next day the same and so on.I noticed that executing the following in a CMD Window displays wrong date and time:systeminfo find "System Boot Time"ONLY when the PC is restarted the System Boot Time is updated.Any idea, suggestion, fix, explanation about this incorrect data?

:)

 

systeminfo reports wrong boot time

systeminfo reports wrong boot time while fast startup is enabled. Is there any solution to this without disabling Fast startup feature. You can create virtual Ethernet and a virtual connection, so when you check it's status, the connection time is shown. From here we can find the system total wake time. Just an idea. is this possible?

Unfortunately, there is no fix for this. Technically, if fast startup is enabled, when you shutdown the system, the system logs off the user and puts the device into hibernation.

As far as I know, to refresh the uptime, the only workaround is to reset the WMI repository (which can break third-party apps in some configurations) at every shutdown. Incorrect Uptime Reported by Task Manager and WMI.
