How to disable Windows 11 Defender Credential Guard?

Anonymous

After upgrading to Windows 11 2022H2, RDP always prompts for credentials and Edge Dev doesn't autofill credentials. According to this, Windows 11 H2 enables Windows Defender Credential Guard. I tried to follow the steps to disable it in the Group Policy Editor (it was set to Not Configured) and rebooted, but it doesn't help. How to resolve this scourge?

BTW, shouldn't we enable such features by default and leaving users to figure out to restore the old behavior for hours, instead of asking on install?

    I've found you also need to set the key in the current control set :
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    Create a new DWORD LsaCfgFlags and set it to 0

    Copy the following into a .reg file to do both


    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceGuard]

    "LsaCfgFlags"=dword:00000000

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]

    "LsaCfgFlags"=dword:00000000


    You will need to reboot for it to take effect.

    It looks like I found a solution. As mentioned in the article, create the following DWORD registry key and set it to 0:

    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceGuard\LsaCfgFlags

    I didn't have it, so I had to create it. Reboot. RDC will still prompt you the first time you remote in, but it will remember credentials after that.

    Roll back such as a massive update? I'm sure that the next auto update will have that "feature", so I'd like to know how to disable it given that both Credential Guard and Remote Credential Guard seem not to be enabled and yet I'm asked to fill in credentials. My laptop is not joined to a domain, BTW.

    This is the way.

    Thank you so very much.
