Quick Assist is built into Windows, needs no port forwarding and works through NAT. The helper sends a code, the user approves the session, and both sides see the same screen.
Both sides open **Quick Assist**, the helper chooses **Help someone else** and shares the six-digit code, the user enters it under **Get help**. The session runs in a window, not as a background service.
Quick Assist is a Store app and can be removed by a debloat script. Check the package before you promise support, and install it from the Store if it is missing.
Get-AppxPackage -Name Microsoft.RemoteAssistance | Select-Object Name,Version,Status
Get-Command quickassist.exe -ErrorAction SilentlyContinue
winget install 9P7BP5VNWKX5 --accept-package-agreements --accept-source-agreements**Help someone else** generates a code that is valid for ten minutes. The code is the only thing the user needs; no IP address, no firewall rule, no account on the target.

Some builds require a Microsoft account for the helper role only. Sign in with a personal account; the target machine needs no account at all.
The user must keep the approval dialog open on their side. Re-request control from the toolbar and check that the session is not paused.
Reinstall it from the Store with the winget command above. Quick Assist is not part of the base image on all editions.
Yes, the session is encrypted in transit and relays through Microsoft. Nothing is exposed on the local network.
No. Every session needs the user to enter a code and grant access, which is exactly why it is safe for family support.
No. Remote Desktop connects to a machine and takes over its session; Quick Assist shares the screen a person is already using.
Nothing is installed on the target machine. Close the session window and remove the Store app with Remove-AppxPackage if you added it only for the call.
