Windows actually has a built-in remote assistance tool now called Quick Assist. It provides a simple way to remotely control another Windows machine with user consent, without requiring third-party software. It's preinstalled on Windows 10 and 11—just launch 'Quick Assist' from the Start menu, generate a session code, and connect. While it's not as feature-rich as a full remote desktop solution, it's more than enough for parental IT support.
