Cannot get W11 to recognise British Summer Time and then stick with it

Here we go again .. .. same trouble as last year.
The clocks in UK went forward early on Sunday.
I've got two W11 machines. At every new switch-on they show the old time (one hour back) i.e. GMT and the Time Zone shows UTC+0.00 (Dublin, Edinburgh, London).
I can, and do, press Sync Now but it is a pain to have to do this every time. I have Settings set to
Time Zone (auto) | Time (auto) | Adjust for daylight saving time (On)
but this does not seem to do the trick. Any instructions?
Thank you!

Fergus,

I have just about the same settings and mine works reliably.


- You don't mention Region [shown in the upper right of my picture] but I assume that is set to UK or Ireland.
- I do not have Location enabled.
- I do not have Set the time zone automatically set, as you can see, because I cannot see any point in doing so. If you have it set & your location is way off then that might cause your problem, I suppose, but you would have mentioned that.

Since it is a fault within a Windows function, I do wonder if you have tried SFC.
SFC - ElevenForumTutorials - use Option 1
If that's clear then a repair install would be worth trying.
Repair Install Windows 11 with an In-place Upgrade - ElevenForumTutorials
This is a repair procedure not a reinstallation, your apps & data files are safe. I always make a new system image & backup my own files before a Repair install.


Best of luck,
Denis
