    A cumullative update to 22H2 was released today.
    After its installation, the system clearly interpreted the saved passwords differently. After deleting them and rewriting, everything returned to normal.
    So, problem was in 22H2.

    KB5017389 seems to have corrected the problem.
    https://support.microsoft.com/en-us/topic/september-30-2022-kb5017389-os-build-22621-608-preview-62f353a0-696a-49d8-a78f-a14910f30ae3

    The only thing I see in the release notes is this:

    • Addresses an issue that causes LogonUI.exe to stop working. Because of this, you cannot dismiss the lock screen to view the credentials screen.

    All seems ok now.

    Today I installed next updates:

    1. 2022-09 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5017389)
    2. 2022-09 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5017271)
      After that I unchecked "Always ask for credentials" as an effect of that updates (I didn't check this before).

    After several tries (Windows 11 didn't want save my choices:)) finally "using of saved credentials" works.
    Just in case I restarted PC several times to check how permanently is this solution.
    All works fine.
    So, that's next prove that my problem was absolutely the result of Windows update 22H2.

    In the meantime I tries change settings in gpedit.msc to check can they help me.
    "Allow delegating default credentials with NTLM-only server authentication Enabled No
    Allow delegating default credentials Enabled No
    Allow delegating fresh credentials Enabled No
    Allow delegating fresh credentials with NTLM-only server authentication Enabled No
    Remote host allows delegation of non-exportable credentials Enabled No
    Allow delegating saved credentials Enabled No
    Allow delegating saved credentials with NTLM-only server authentication Enabled No
    "
    I don't have time now to check which of the settings may be related to my problem.
    I leave it as it is while it works.

    The link says "Starting with Windows 11 Enterprise 22H2, compatible systems have Windows Defender Credential Guard turned on by default. This changes the default state of the feature in Windows, though system administrators can still modify this enablement state. Windows Defender Credential Guard can still be manually enabled or disabled via the methods documented below.":

    It seems this issue is not going to be "fixed". It is a purposeful change to improve security and you must turn it off if you don't like it.

    These also looked interesting:

    guys this is the solution
    I also have 11 pro 22h2 with this method I have definitely solved
    no longer asks for the password

    win+r then regedit
    after
    go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard.

    add a new DWORD value named EnableVirtualizationBasedSecurity and set its value to 0.
    add another new DWORD value named RequirePlatformSecurityFeatures and set that to 0.

    now go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa.

    add a new DWORD value named LsaCfgFlags and set it to 0.

    very simple
