Unable to remove an inactive/old linked PC from Link to Windows Android app

You have an old PC entry in Link to Windows that is absent from Microsoft Account Devices and survives an app reset, indicating a stale cross-device association rather than a normal device record. Microsoft’s supported unlink process requires cleanup on both sides.

On Android, open Link to Windows, select the signed-in Microsoft account, then choose Sign out and unlink. On the active PC, remove the phone under Phone Link > Settings > Devices and Windows Settings > Bluetooth & devices > Mobile devices > Manage devices. Remove remaining Bluetooth pairings on both devices. Clear Link to Windows app storage, restart both devices, sign in, and pair only the active PC.

If the inactive PC returns after this full unlink-and-relink cycle, the orphaned association is likely service-side. Capture the phone model, app version, screenshot, and account address, then ask Microsoft Support to escalate the stale Phone Link association rather than repeating local resets.
