Why my PC Disappeared From Microsoft Account?

My PC has suddenly disappeared from my Microsoft account device list for the second time, even though it's the same computer I use every day. Around the same time, a Windows update also failed to install properly, and I'm wondering if the failed updates are somehow causing my device registration to get wiped repeatedly.

  • Hi, the Microsoft account device list and Windows activation are related services but not the same record. First confirm Settings > Accounts shows the expected Microsoft account, then check Settings > System > Activation. If Windows is activated, the missing web listing has not erased your license. Sign out and back in, restart, and check the device page again after a few hours. Also make sure you are viewing the correct personal or work account. If it repeatedly disappears, use Microsoft account support and provide the device serial number. I would troubleshoot the failed update separately with the Windows Update troubleshooter, DISM, and SFC.
