Set up & use Windows Remote Assistance
Press Win+X and from the menu, select ‘Control Panel’. Search “System.” The window will display all of the basic specifications of your computer such as model number, CPU configuration, installed memory, etc.
Navigate to the Remote tab in System Properties now and select the Allow remote assistance to this computer option and click hit the ‘Apply’ button. If you uncheck this option, it will disable Remote Assistance.
You can even configure certain settings here. For instance, you can set limits for the use of remote assistance, choose to allow the computer to be used remotely, set the maximum amount of invitations.
If you find that your Windows Firewall is blocking Remote Assistance, create a rule to allow it. To do so, open the “Run” dialog box. Type “Firewall.cpl” in the text field and click “OK.’ Windows Firewall control panel will be launched. Go to the left pane and click “Allow an App or Feature through Windows Firewall.”
You should find a list of devices that are disabled/enabled through Windows Firewall. Click “Change Settings.”
Scroll down until you find “Remote Assistance” option. When you find it, click the option to allow remote assistance. Open an elevated command prompt, type msra.exe and hit Enter to open Windows Remote Assistance. Follow the on-screen wizard. Click on Invite someone you trust to help you or Help someone who has invited you, as the case may be. Let’s say you want to invite someone to have a look at and operate your computer. Click on Invite someone you trust to help you.
You can generate the invitation as a file or use the email to send an invitation or use Easy Connect. I prefer the Use email to send an invitation.
The Invitation file will then be sent to your friend using your email client.
Your friend will then have to enter the code in his Remote Assistance box. After this is done successfully, the two computers will get connected. Once your work is completed, remember to disable this feature.
