Windows Task Manager>Performance>CPU>uptime

Running Windows 11 23H2 22631.3085

Has anyone else seen this?

I powered on my system about 430am this morning. A little while ago I went into Task Manager>Performance>CPU and it was showing that my CPU uptime was a little over 10 hours.

My system is set to Never Hibernate or Sleep or to "wake" up and perform tasks.

So why is it showing 10 hours and I just turned on my system a little over 2 hours prior? Is this some type of bug in Windows 11? (I was running a full system scan at the time of the screen shot)..Edit This system is dual booting so I restarted and booted into the Dev channel. It's CPU uptime was correct. When I rebooted into this system, at that time the CPU uptime was correct...So I wonder what caused this...

 

Incorrect Uptime in Task Manager

I've just got Cumulative Update KB 4016240, and after the reboot Uptime in Task Manager has reset to zero.

I guess KB 4016240 has fixed whatever they broke in KB 4015583, on my system at least.

Thanks,
Dave.
