Remote control tools let you share your screen or take control of another PC over the internet—common for IT help, working from home, or supporting family members.
Most programs work the same way: the person being helped runs the app and reads out a session ID (and often a one-time password). The helper enters that ID to connect. Sessions should be short, and you should only accept connections from people you trust.

AnyDesk
Known for a small install footprint and responsive performance on slower networks. It supports unattended access (optional, with permission) and file transfer during a session. Free tiers exist for personal use; business use typically needs a paid license. Always download from the official AnyDesk website and treat ID/password like a temporary key—never post them publicly.

RustDesk
Open-source remote desktop software. You can use RustDesk’s public relay servers or, for organizations, run your own server for more control over data. It uses an ID + password model similar to other tools. Good choice if you want transparency in the codebase or self-hosted infrastructure; still verify download sources and keep the app updated.

TeamViewer
One of the most widely used commercial solutions, with clients for Windows, macOS, Linux, and mobile. Features include remote control, meetings, file transfer, and (with setup) unattended access for managed devices. Free use is limited to personal/non-commercial scenarios as defined in their terms; businesses need a subscription. After a session, revoke or change passwords if the tool allows, and uninstall if you no longer need it.
