AMA: Windows LAPS

I would like to keep LAPS 6 (which is installed as a separate MSI-installed application) working as-is after installing the 2023-04 or 2023-05 Security Updates on a Windows system (Server or Client) that already has LAPS 6 installed on it.

Is "disabling the legacy Microsoft LAPS Emulation mode" the right way for this scenario, or is there another/better way?

If that would be the right way then I would like to know more about the options on how to disable the legacy Microsoft LAPS Emulation mode.

   I've have got the following questions regarding this:
At https://learn.microsoft.com/en-us/windows-server/identity/laps/laps-scenarios-legacy#disabling-legacy-microsoft-laps-emulation-mode
it says "To prevent this you can disable legacy Microsoft LAPS emulation mode by creating a REG_DWORD registry value named BackupDirectory under the HKLM\Software\Microsoft\Windows\CurrentVersion\LAPS\Config key and set it to the value zero (0)".
In another documentation, https://learn.microsoft.com/en-us/windows-server/identity/laps/laps-management-policy-settings it says "If not specified, this setting defaults to 0 (Disabled)."

   To me this begs the question: Is there a difference between specifically creating the BackupDirectory REG_DWORD registry value and setting it to value 0 (as advised in the first web page) vs. not creating the BackupDirectory REG_DWORD registry value at all?

• If there is no difference, my reasoning would be that Windows LAPS would therefore by default running with disabled legacy Microsoft LAPS Emulation mode - correct?
• If there is a difference, would it be possible to create the BackupDirectory REG_DWORD registry value and setting it to value 0 even before installing the 2023-04 or 2023-05 Security Updates (which include Windows LAPS) with the intention of causing Windows LAPS to pick up and honor that setting from the instant it gets enabled on a Windows system (Server or Client)?

Another question: How can one tell/detect that Windows LAPS is running with disabled legacy Microsoft LAPS Emulation mode on a given Windows system (Server or Client) - only by checking the above-mentioned Registry Key?
