Note for : this is a very common symptom. On Windows 10 (and later) the OS can automatically make the last-used printer the default; disabling that behavior stops most unexpected changes. For older systems (Windows 7 / 8.1) the default is set manually via Control Panel, so the problem is usually something else if it keeps flipping. Official Microsoft steps for setting a default printer are here: Set a default printer in Windows (Microsoft Support).

Quick fixes (apply the one that matches the OS):

  • Windows 10 / 11: Settings → Bluetooth & devices → Printers & scanners → turn off "Let Windows manage my default printer", then choose the desired printer → Manage → Set as default. See Microsoft Support for details.
  • Windows 7 / 8.1: Control Panel → Devices and Printers → right‑click the printer → Set as default.

Scripted / administrative options:

  • Command-line (works in scripts or logon tasks):

    rundll32 printui.dll,PrintUIEntry /y /n "Printer Name"

    (Official CLI reference: Microsoft documentation for PrintUIEntry.)

Persistent / enterprise fixes:

  • For stubborn machines, enforce manual default with the user registry flag LegacyDefaultPrinterMode = 1 under:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows

    A .reg file can apply this, but back up the registry first and use Group Policy/Intune for wide deployment (see Microsoft ADMX/Policy documentation).

Other causes to check: login scripts, roaming-profile or profile-restore behavior, printer-mapping policies on a print server, or Remote Desktop client printer redirection — any of these can reassign the default at logon or session start; Microsoft docs cover ADMX/Terminal Server settings and roaming-printer behavior for enterprise scenarios.
