Stop Windows from changing my default printer — policy, registry, Intune
Quick answer: the accepted fix
Accepted fix when Windows keeps changing the default printer:
Turn off “Let Windows manage my default printer”, add
LegacyDefaultPrinterMode=1 in the user registry, and set a fixed default printer
via PowerShell or the Manage button. Optionally enforce with Intune/GPO and block
RDP redirection from overriding the default.
Default printer changes after update or logon — keep it locked
Profile refreshes and Windows feature updates can re-enable smart defaults. The LegacyDefaultPrinterMode registry value prevents the OS from auto-selecting the last used printer. Combine this with a Standard TCP/IP Port queue and a PowerShell script to set the default at login for guaranteed persistence.
How to verify the default printer stays fixed
Print from two different apps (Word and a browser). After switching printers inside an app, reopen Settings → Printers & scanners and confirm your preferred printer is still marked Default. If it flips again, re-check the toggle and ensure the registry key is applied to the user.
Make a default printer truly permanent
Disable the auto-manage feature, enforce registry policy, and script the default.
Quick path: toggle off auto-manage → deploy LegacyDefaultPrinterMode=1 →
Set-Printer -IsDefault $true for your production queue → block RDP default takeover.
This resolves “Windows keeps changing my default printer” for both Windows 10 and Windows 11 environments.

FAQ
Why does Windows keep changing my default printer?
With “Let Windows manage my default printer” enabled, Windows sets the default to the last printer you used. Turn the toggle Off and add LegacyDefaultPrinterMode=1 to stop auto-switching.
How do I disable “Let Windows manage my default printer” permanently?
Toggle it off in Settings → Printers & scanners, then enforce HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LegacyDefaultPrinterMode=1 via Intune or Group Policy.
Can I set a default printer via Intune or Group Policy?
Yes. Deploy a PowerShell script that adds the printer (TCP/IP or shared UNC) and runs Set-Printer -IsDefault $true. Combine with the registry key for persistence.
How to stop RDP from changing the default printer?
Enable the RD Session Host policy “Do not set default printer to be the same as the connected client’s default printer.” This blocks redirected printers from taking over.
| Symptom | Likely cause | Quick fix |
|---|---|---|
| Default printer keeps changing | Auto-manage toggle enabled | Turn off toggle; set LegacyDefaultPrinterMode=1 |
| Users lose default after reboot | Registry not enforced | Deploy key via Intune or GPO |
| RDP session changes default | Redirected printer takeover | Enable RD policy to prevent default match |
| Wrong queue selected | Per-app last-used behavior | Use PowerShell to set a global default on login |
Step‑by‑step (Windows 10/11)
- Open Printers & scanners → toggle Let Windows manage my default printer to Off.
- Create
HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LegacyDefaultPrinterMode(DWORD) = 1. - Add your printer (TCP/IP or UNC) and run
Set-Printer -IsDefault $true. - Optionally deploy via Intune or Group Policy and set the RDP policy to block redirected default.
Step‑by‑step (macOS)
- This Windows feature doesn’t exist on macOS. To keep a fixed default on Mac, open System Settings → Printers & Scanners and select Default printer as your preferred queue or Last printer used per your workflow.
- In mixed fleets, manage Mac defaults via configuration profiles (PPD/IPP) if needed.
