How to Revoke Remote Access to a Computer: Stop Unwanted Access

What Does Revoking Remote Access to a Computer Mean?

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.

What Are the Benefits of Revoking Remote Access?

• Protect privacy by removing unnecessary access to your screen and files.
• End outdated permissions after a repair, contract, or job ends.
• Reduce exposure from unused remote services and shared access codes.
• Keep future support under your control through fresh approval.

Revocation cannot recover files someone already copied or undo changes they already made.

How to Revoke Remote Access to a Computer: Step by Step

1. Stop the active connection

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.

2. Identify the access method

Check installed apps, the system tray or menu bar, and remote-service settings. More than one tool may be installed.

3. Disable built-in Windows or Mac access

On Windows 11 Pro, Enterprise, or Education:

1. Open Settings > System > Remote Desktop.
2. Turn Remote Desktop off and confirm if prompted.
3. If legacy Remote Assistance is enabled, press Windows + R, enter SystemPropertiesRemote, and clear Allow Remote Assistance connections to this computer. Select Apply.

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.

4. Remove app-specific access and saved permissions

For Chrome Remote Desktop:

1. Open Chrome Remote Desktop.
2. Find the computer and select Disable remote connections.
3. Uninstall its host component if you no longer need remote access.

Google distinguishes ending a session from disabling remote connections.

For AnyViewer or another support tool, review each enabled connection method:

• Disable unattended access and any saved permanent security code you no longer need.
• Revoke shared-device permissions and account assignments that grant access.
• Rotate exposed access codes and secure the associated account.
• Uninstall the host software if no remote access should remain.

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.

5. Secure accounts if access was unauthorized

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.

6. Verify that reconnection is blocked

After routine, authorized support access has been removed:

• Restart the computer and confirm disabled settings remain off.
• Check that the removed host software has not returned.
• From a device you control, test the former connection method using the old authorization.
• Confirm it fails or requires fresh approval, depending on your intended setup.

A failed test verifies that route only. If you suspect compromise, keep the computer isolated until IT or a trusted technician has assessed it.
