How to Turn Manage Default Printer on or off in Windows 10 & 11
Windows 10 features a unique setting that can set the last used printer as your default printer. While this might work for most people, you might want to manage the default printer yourself.
Click Start > Settings > Devices.
Click on Printers & scanners.
Check or uncheck Let Windows manage your default printer on the right.
We can also make the changes by downloading our registry files or editing the registry.
Advanced users can navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows and modify the Value data of LegacyDefaultPrinterMode. 0 is on and 1 is off.
