To learn how to revoke remote access to a computer, start by ending active sessions, then disable the service or remove the permissions that allow reconnection. This guide helps home users and remote workers check Windows, Mac, and third-party tools, secure exposed accounts, and verify the results.
Revoking remote access means removing another person's ability to connect to your computer through a remote service, account, or saved authorization. Disconnecting ends a session; revoking access blocks the route used to reconnect.
For example, closing a support window may leave an unattended-access service running. You must disable that service or remove its authorization separately.
Revocation cannot recover files someone already copied or undo changes they already made.
Select Stop Sharing, Disconnect, or End Session in the remote-support app. If someone is controlling the computer without permission, turn off Wi-Fi and unplug the Ethernet cable. Disconnect other active network connections too.
Network isolation interrupts access but does not remove saved permissions. Work at the computer locally; otherwise, you could cut off your own route before finishing. For a company-managed device, contact IT from another device.
Check installed apps, the system tray or menu bar, and remote-service settings. More than one tool may be installed.

On Windows 11 Pro, Enterprise, or Education:
Windows Home does not host Microsoft's built-in Remote Desktop, but third-party tools can still provide access. Microsoft's Remote Desktop documentation explains the edition differences.
On a Mac, open System Settings > General > Sharing. Turn off Screen Sharing, Remote Management, and Remote Login if you do not need them. Remote Login controls SSH access separately from screen control. See Apple's screen-sharing instructions and Remote Login settings.
These switches do not disable every third-party app. Continue with the next step.
For Chrome Remote Desktop:
Google distinguishes ending a session from disabling remote connections.
For AnyViewer or another support tool, review each enabled connection method:
Removing a shortcut or closing the app window may leave its background service active. In AnyViewer, temporary codes, fixed codes, and account-based access are separate routes; changing one code is not a complete revocation check.
From a trusted device, change exposed passwords, starting with email and the remote-access account. Use available sign-out-everywhere controls, review recovery details, and enable multifactor authentication.
Update the affected computer and run a security scan. If a scammer had access, follow Microsoft's tech-support scam recovery guidance; a reset may be appropriate. A clean scan alone cannot prove that no changes were made.
For business offboarding, ask IT to revoke the person's VPN, identity-provider sessions, and remote-management permissions as well.
After routine, authorized support access has been removed:
A failed test verifies that route only. If you suspect compromise, keep the computer isolated until IT or a trusted technician has assessed it.
Once your system is secure, you may still need reliable remote access for remote work, cross-device file transfers, IT management, or helping friends and family.
Traditional remote desktop tools can be clunky, insecure, or overpriced. AnyViewer provides a modern, high-performance alternative designed with bank-grade security and granular permission controls at its core.
