I was using Windows 11 Build 22000.65 without any issues, although on i5 7th gen, but with TPM 2.0, UEFI, secure boot (but the 1st login was a disaster - no explorer / desktop, I solved it by turning off the AppReadiness service). However issues came with the update of 22000.100. I could not install it via Windows update, as it crashed always by 95-99 (or even 100)% with error "0x800f0922" and restored the previous compilation (I think 4 times at least). However it was successful to install it via UUP dump without any issues. I was lucky but suprised with the new build so quickly, meaning 22000.120. I installed it via Windows Update and it was also successful until the first login, which was unsuccessful (local login, but solved by logut /login again.) However since then the taskbar did not have any icons, there was no start menu obviously too (even Win key does not open it), no clock but only the notification corner with the hidden icons. No settings could be opened, as I tried per right click on desktop to go to preferences etc, I got a message that no programm is assosiated with this command. Restarts did not help. However I could succesfully login on other 2 Microsoft accounts used on this laptop, which were for 100% not used before upgrading to Win11. All worked here fine, the new context menus etc. I have added a 4th MS account to this PC, never used anywhere, and for a while it worked perfect. But after next reboot this account (and only this 4th one) got the initial issue (build 65) with no desktop. I am using the Samsung LC49RG monitor, as a second one, but not using the one on laptop. No issues with taskbar on 22000.65 & 100. What is also weird, is that when I login on my main (1st) account + on the new (4th) one I have a blue background on the lock screen, and when i am trying to log on the 2nd and 3rd which were not used before upgrade it switches to Windows spotlight background (this I am not able to turn on for the other ones). It seems that the main account could be corrupted somehow. But working well on the 100 build. Now I turned off the updates for a while, don't know if I should try once again via Windows update or UPP dump, but if I don't install the 120 I would not be able to install the next one later? Any ideas what could go wrong here? Many thanks and Regards, Rafal
