MY COMPUTER

If the Quick Assist window shows no active session—or you selected Leave, closed Quick Assist, or restarted the computer—the support session has ended; another connection requires a new security code and your permission.

Quick Assist requires you to enter a time-limited code, select Allow for screen sharing, and separately approve any request for full control. During a session, selecting Cancel control stops control, while Leave ends the session.^1^

Confirm access has ended

1. Restart your computer.
   • Select Start → Power → Restart.
   • Do not enter another Quick Assist code or approve another connection.
2. Open Quick Assist and check its state.
   • Press Ctrl + Windows key + Q.
   • If it displays the normal screen asking for a code, rather than showing an active support session, that session is no longer connected.
3. Optionally remove Quick Assist.
   • Go to Settings → Apps → Installed apps.
   • Find Quick Assist, select … → Uninstall. Microsoft documents this as the supported removal path.^2^
   • This is optional; leaving Quick Assist installed does not itself give someone control. A new session still requires a code and your approval.
4. Check Windows Remote Desktop separately.
   • Go to Settings → System → Remote Desktop.
   • If it is On and you do not use Remote Desktop, turn it Off. Windows documents this page as the place where Remote Desktop access is enabled or disabled.^3^
5. Check the older Remote Assistance setting.
   • Search Windows for Allow Remote Assistance invitations to be sent from this computer.
   • Open it and, if you do not use this feature, clear Allow Remote Assistance connections to this computer and select OK.^4^

If you are uncertain that it was genuine Microsoft Support

Microsoft says to allow remote assistance only when you initiated contact with Microsoft Support directly. Microsoft does not make unsolicited calls offering technical support.^5^

If Microsoft contacted you unexpectedly, you called a number displayed in a pop-up, or they installed another remote-control program:

1. Disconnect the PC from the internet temporarily.
2. Go to Settings → Apps → Installed apps and uninstall unfamiliar remote-access applications installed during the session.
3. Open Windows Security → Virus & threat protection → Scan options → Full scan → Scan now. Windows Security is built into Windows 11 and supports manual malware scanning.^6^
4. Go to Settings → Windows Update → Check for updates and install available security updates.
5. From a different trusted device, change passwords for your Microsoft account, email, banking, and any account opened during the remote session.
6. If payment information was disclosed, contact the card issuer or bank immediately.
7. If suspicious programs, repeated fake warnings, or unexplained account activity continue, back up personal files and consider resetting Windows. Microsoft specifically recommends uninstalling software installed by a suspected scammer, running a full scan, changing passwords, and considering a PC reset after unauthorized access.^5^
