'Standard hardware security not supported', till now the error is not fixed in Version 10.0.22621.674 also.

I also noticed if I set Memory Integrity to OFF the Device Security shows an exclamation. I am able to access Device Security and turn it back on. It was weird though because everything was fine yesterday and at bootup today I was taken to a screen to complete my set up, but I already did all that yesterday morning after a factory reset, and rebooted a couple times. Today at boot up I saw the exclamation on Windows Security. In the end, all is well again but don't know why I randomly get a "finish setup" screen at setup. Maybe the Experience Package software is turned on?

Thanks Enric!

You have been very helpful! I am not super techy but I know a bit from being a IT Helpdesk/Sys Tech for 16 years; however, out of the workforce the past 3 years. Some of the issues are probably user error - ID 10 IT - and not bugs, just the new UI and the new version. I decided to leave Protection History/Controlled Access Folder off as it was blocking most apps, programs and files. I guess I can turn it on and just keep selecting allow. I have an accent colour set in personalization and found I can see the accent colour in the File Explorer title bar but only if I run sfc /scannow at startup. Once I shutdown the colour reverts to grey at next startup. No biggie, just an observation that the chosen accent colour only stays present on all other title bars except the File Explorer.

You're the best Enric!

I'm impatient and I did it myself with Enric's fix. It looks like MS dropped the Windows Security app from the MS Store. It is not there. It is documented that it is built into Windows Defender but appears to not be integrating properly. I believe Microsoft needs to either add the app back to the store as a downloaded app and/or add the file to the Microsoft Defender app and point it to the Security Health folder in the C drive. I ran the WIN11 update, that's when the issues started. I looked and no Windows Security in my App Tray, only in my System Tray. Also, Secuity Health folder was empty - no Windows Security files. I uninstalled and reinstalled the update 2x, no resolve. I did a factory reset 2x times which reinstalled the newest version of WIN11. Still no resolve with Device Security exclamation mark and unable to access it. Enric's download fix shows the file reinstalls from the Microsoft Store App but there is no longer such app in the store and it works. The app is now my App Tray and System Tray and is functioning correctly. The latest update is quite a pain if Protection History is turned on. I have to allow my previously owned apps, files and programs to the Controlled Access Folder. I don't remember doing this when I switched from WIN10 to WIN11 last year. However, I had Mcafee until I decided to just use Windows/Microsoft virus software since the WIN11 update in Oct so maybe that's why? I guess I could turn it off but then afraid of further issues so it's just easier to select Allow when I get the security popup.
