Hello, I accidentally connected my personal PC to my work account and it applied several policies that I don't want on my personal PC.
To revert it I disconnected the account from Settings -> Accounts -> Access work or school. This didn't revert anything though.

I think I was able to manually re-enable the PIN-code I was previously using to sign in after this but I still cannot change my lock screen.
It still says "Some of these settings are managed by your organization".

I checked gpedit.msc for any kind of policy changing this but I have no policies at all configured. I checked "Computer Configuration -> Administrative Templates -> All settings" sorted by "State".
Same for "User Configuration".

I also ran all of these commands as administrator:
"
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKLM\Software\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f
reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /v DisableAntiSpyware
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f
reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f
reg delete "HKCU\Software\Policies" /f
reg delete "HKLM\Software\Microsoft\Policies" /f
"

It deleted a few keys but after restarting I still am not allowed to change my lock screen?! I asked IT in the company how they changed the lock screen and they said it was set by "Intune Microsoft Endpoint Manager" (MeM). Is there any way I can reset the damage that was done and get control of my lock screen again without reinstalling my personal PC?

    I was able to finally unlock the lock screen by deleting this registry key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PersonalizationCSP

    Although I'm not sure if there's any other unwanted settings still left on my PC so if anyone knows of any better way to revert/delete everything that could have been applied through MeM please let me know.
