I saw you reply to Saltgrass and test this opt-out on all three device on Beta build 22622.290 and it was working just like I shown on my reply.
There may have something wrong on your system. There is some things you can try to fix:
- Open Command Prompt (CMD) As Administrator and give command: DISM /Online /Cleanup-Image /RestoreHealth
- Open Command Prompt (CMD) As Administrator and give command: sfc /scannow
- Do in-place repair. Download Windows 11 Beta channel ISO: Download Windows Insider Preview ISO (microsoft.com)
Mount (double click or right click and select mount) that ISO. On new virtual CD/DVD drive run setup.exe to start in-place repair
NOTE:
If you don't have up to date backup from your valuable files then you should do just in case.
Its always important to have backup, you never know when something disastrous happen
