How to Prevent Windows 10 From Changing Default Printer Automatically For example, if you occasionally use a different printer or use Acrobat PDF Printer, you have to change the printer back to regular default when next time you print. This can be annoying for some users who might prefer to set the default printer manually because Windows 10 will set the new default printer automatically every time you select a printer different from the default one in the print dialog. Let Windows manage my default printer option is checked/enabled by default. This new option will now change your default printer to the last used printer at your current location automatically to ensure the best printer is preselected in inbox print dialogs. Microsoft has implemented a new behavior called Let Windows manage my default printer for default printer in Windows 10 build 10565.
