If you are concerned that someone can access your Windows 10 PC remotely, first remove unnecessary remote-access paths and secure the accounts that could authorize them. Do not assume every cursor movement or pop-up proves an intruder is connected; software bugs, touchpads, sync tools, and legitimate support applications can produce confusing behavior.
Reduce remote-access exposure
- Disconnect the PC from the network temporarily if you see active unauthorized control.
- Open installed apps and identify remote-control products you did not install or no longer use.
- Check Settings > System > Remote Desktop and disable Remote Desktop if you do not need it.
- Review Remote Assistance settings and organization-approved management tools.
- From a separate trusted device, change passwords for important accounts that may be compromised and enable multifactor authentication.
- Run Microsoft Defender Offline or another trusted security product’s offline scan.
- Review router remote-management settings and account sign-in history where relevant.
Do not expose Remote Desktop to the Internet
Remove router port forwarding that directly exposes RDP unless it is part of a professionally secured design. For legitimate remote work, use a VPN, Remote Desktop Gateway, zero-trust service, or another organization-approved solution with strong authentication.
Uninstall remote tools normally
If you find a legitimate remote-support product you no longer want, use its normal uninstaller and remove unattended-access permissions from its account portal if applicable. Simply deleting a program folder may leave services or account authorizations behind.
Preserve evidence on business devices
If the PC belongs to an organization or you suspect a serious intrusion, contact IT/security before wiping logs or reinstalling. The incident may involve other systems.
Windows 10 standard support ended October 14, 2025. Rebuild compromised PCs on a supported platform whenever practical.
Also review browser extensions and startup applications. Some unwanted remote tools launch at sign-in or operate through a browser rather than appearing as an obvious Remote Desktop session.
If account compromise is suspected, check email forwarding rules and recovery methods because attackers can maintain access to online accounts even after the PC is cleaned.
