Windows keeps changing default printers

Question

I have two session hosts in Azure VDI that I am using for user sessions with FSLogix being utilized for user profiles. I have multiple users whose default printer keeps changing to a "virtual" printer such as the Adobe PDF printer or a Webex Printer that is installed. This happens randomly and at differing intervals. The printers are hosted on another server and deployed using group policy. Windows is not managing default printers. I have also tried the Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LegacyDefaultPrinterMode key to prevent windows from changing the printer. I have seen the changes correspond with logoff times, but it has also happened at random times while the user is online and even when the user was not logged in. I am tracking this using the Event Viewer ID 823. I am posting a follow up with the actual event details.

Answer 1

This is a rather odd one...
In a regular situation, I would say alter the registry of the current user or back it up and take the one of a working user/computer and overwrite it.
I am not sure about FSLogix, not too familiar with it myself..
Locally you could do atleast the following:
Add this registry key: GpNetworkStartTimeoutPolicy DWORD set value at 120 decimal for 120 seconds to this HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\

With GPO:
Computer Configuration/Administrative Templates/System/Logon/Always wait for the network at computer startup and logon

Also consider this clearing out this (test with a user; backup first tho)
HKEY_USERS\USERS_SID_HERE\Printers\Settings key

Let me know if it works!

Hope it helps!
