What you’re seeing
- Choosing a new default printer shows 'Operation could not be completed (error 0x00000709)'.
- Windows switches the default back to the last printer used, or to a PDF printer, without being asked.
- Every document goes to the wrong printer unless the user picks one manually each time.
- The problem affects one user profile while others on the same PC can change the default.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The setting that lets Windows manage the default printer is on, so Windows changes the default based on recent use or location.
- The user's registry entries for printer settings have wrong permissions or are corrupted, so the change can't be saved.
- Stale connections to printers or print servers that no longer exist remain in the user's profile.
- A Group Policy or login script reassigns the default printer each time the user signs in.
- A Windows update introduced a known issue affecting how default printers are stored.
Why it matters
Documents printing on the wrong device sound minor, but they can send payroll, HR or client documents to a printer in a public or shared area. Staff waste time walking to the wrong printer, reprinting, and correcting the setting over and over. In offices with check or label printers, the wrong default can also waste expensive stock.

Frequently asked questions
Is this a printer problem or a computer problem?
It's almost always on the computer or user profile side. The printer itself prints normally once the right one is selected.
Will the user lose other settings when this is fixed?
Generally no. The work targets printer-related settings, and the engineer tells you beforehand if anything else might be affected.
