Windows 11 CO-Release Build 22000.51 is out to Dev Channel

This has to be an error on your side, I can change from dark to light and back again pretty much instantly

@SimonCole2,

I don't think so, I've seen the delay on 3 different machines now also on this one, even if not as severe as the other 2 older machines.

I'd blame it on the developers... 😉

Only problem here is the CU will not install and I get an error and a 'try again' message. Basic Windows 11 is here but not the update that I hear adds parts that are missing in initial install.

None of my other Dev builds are installing at all.

What kind of graphics card do you have ?

Do you have the latest drivers installed ?

Not everything is just the Windows side of it your hardware might have a bottleneck you are unaware of or an accessory connected that is keeping your system busy.

If you could switch back to prior Windows would the problem go away ?

I'm experiencing a HUGE! delay of almost 30 seconds changing from light to dark & vice versa, anyone else?

edit: this is new clean install

Yes I see a long delay.

Time for another FBH report.

Thanks for the confirmation.

My Raspberry Pi4 clean install does the same but I waited for one to be 100% sure.

I've seen it on 2 machines. About 15-20 secs.

I'll try later on a faster machine that meets all the hardware requirements.
