Duplicate printers W2012

Question

Hello, we have installed Windows Server 2012 R2 with print server. We have 12 printers. Workstations have installed Windows 10 Pro. Each user have install some printers using GPO. Users have roaming profile. Everything was OK last three years.
we have this problem last month...users see every printers others users in Control panel and printers are duplicated with every login. We have for example 70 or more printers in control panel on some PC.
When but user open print dialog for example in notepad, he see only correct printers by GPO.

I tried delete keys from regedit by:

https://www.amorales.org/2019/05/duplicate-printers-showing-up-in-windows.html
but not working for me

There are many devices Xerox Desktop Print Experience in device manager in software components
When i unnistall devices, all is OK.
Unfortunately... they are again installed after restart PC.

This isn't specific to Xerox. I've seen it with a multitude of various printers from different manufacturers, but I've only ever seen it happen on Windows Server operating systems, not clients. The only method of preventing it that actually seems to work, is to set the following registry key:

Windows Registry Editor Version 5.00  
  
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider]  
"RemovePrintersAtLogoff"=dword:00000000  

Cleanup is a highly manual process, and close to what @Kajbl posted earlier. This should only be done after you've deployed that key. You'll need PsExec. Here's what you'll need to do.

First, open an elevated powershell session:

Stop-Service spooler -Force  
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Connections" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\V4 Connections" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Print\Connections" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Print\Printers" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Print\Providers" -Recurse  
Remove-Item -Path "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Print\V4 Connections" -Recurse  
Remove-Item -Path "HKCU:\Printers" -Recurse  
Remove-Item -Path "HKCU:\Software\Microsoft\Windows NT\CurrentVersion\PrinterPorts" -Recurse  
Remove-Item -Path "Registry::HKEY_USERS\.DEFAULT\Printers" -Recurse  

You might get a bunch of errors about nonexistent keys. Disregard them and move on to the next step.

Then, open an elevated command prompt and run the following command -- this is necessary because you need a powershell session running within the SYSTEM security context:

C:\Path\To\PsExec.exe -i -s powershell  

Then copy and paste the following into your nested powershell session:

Remove-Item -Path "HKLM:\SYSTEM\CurrentControlSet\Enum\SWD\PRINTENUM" -Recurse  
Remove-Item -Path "HKLM:\SYSTEM\CurrentControlSet\Control\DeviceClasses\{0ecef634-6ef0-472a-8085-5ad023ecbccd}" -Recurse  
Remove-Item -Path "HKLM:\SYSTEM\ControlSet001\Enum\SWD\PRINTENUM" -Recurse -ErrorAction SilentlyContinue  
Remove-Item -Path "HKLM:\SYSTEM\ControlSet001\Control\DeviceClasses\{0ecef634-6ef0-472a-8085-5ad023ecbccd}" -Recurse -ErrorAction SilentlyContinue  
Remove-Item -Path "HKLM:\SYSTEM\ControlSet002\Enum\SWD\PRINTENUM" -Recurse -ErrorAction SilentlyContinue  
Remove-Item -Path "HKLM:\SYSTEM\ControlSet002\Control\DeviceClasses\{0ecef634-6ef0-472a-8085-5ad023ecbccd}" -Recurse -ErrorAction SilentlyContinue  
Remove-Item -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{1ed2bbf9-11f0-4084-b21f-ad83a8e6dcdc}" -Recurse   

Reboot immediately.

Hi @Anonymous
Thank you for response.
I tried https://learn.microsoft.com/en-us/answers/questions/194877/rds-w2019-default-printer-lost-on-session-disconne.html
and i had partial success. Problematic printers are greyed out now.
I removed key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SWD\DRIVERENUM and restart PC recreate key DRIVERENUM.
Greyed out printers were removed after restart PC.
All is OK, but driver Xerox Print Driver Experience is again installed for each user, when he login.

And in device manager:
