Windows error 0x00000709
Windows cannot set or change the default printer.
How to fix it
- Open Settings > Bluetooth & devices > Printers & scanners and turn off "Let Windows manage my default printer".
- Then pick your printer and choose "Set as default".
- Still failing: restart the Print Spooler service (Win+R, services.msc) and try again.
Is it worth fixing?
Always fixable.
