Solutions

Solution 1: Basic Connection Steps

1Helper (person giving help): open Quick Assist → "Help someone"
2Sign in with a Microsoft account (required for helpers)
3A 6-digit security code appears — share it with the person needing help
4Person needing help: open Quick Assist → enter the 6-digit code → click Submit
5The code expires after 10 minutes — be quick
6Helper: choose "Take full control" or "View screen" → click Continue
7Person needing help: click "Allow" to grant access

Solution 2: Fix Connection Failures

1If the connection fails after entering the code:
2Ensure BOTH PCs have a working internet connection
3Disable VPN on both PCs during the session
4Check firewall: Quick Assist needs outbound HTTPS (port 443)
5Windows Defender Firewall: allow "Quick Assist" through
6If behind a corporate firewall: the admin may need to whitelist Microsoft RDP relay servers
7Try again with a new code — expired or failed codes can't be reused

2Settings → Apps → Installed apps → search "Quick Assist"
3Click three dots → Advanced options → Repair
4If Repair doesn't help: click Reset
5If still broken: uninstall and reinstall from Microsoft Store
6Quick Assist requires Windows 10 version 1607+ or Windows 11
