Launching Windows 10 Quick Assist

To help another Windows 10 user remotely, launch the Quick Assist app and choose Give Assistance.

3. Sign in with your Microsoft Online account.

4. Quick Assist generates a 6-digit security code. Give this code (by email, instant messenger, text or voice call) to the person whose computer you will need to connect to. After 10 minutes, this code will become invalid.
