Anyway, to begin you need to carry out the following steps:

However, if you are using Windows 11/10, you won’t find the Windows Remote Assistance. Instead, you need to search for that particular settings in the Taskbar search box. You can see a setting called Allow Remote Assistance invitations to be send from this.
Windows Remote Assistance wizard will open. Click on Invite someone you trust to help you. 
Select the option you want. Using the second option will be easy in my opinion. It happens on Windows 7 only. It will open your mail client and you can mail the attached invitation file.
Once the mail has been sent, the following windows will open up mentioning the password. The password will be valid only for the current session.
Now, wait for the other person to approach you. He too will open up Remote Assistance and click on Help someone who has invited you. Once he does, and a request appears on your computer, give him the access password.
If you are using Windows 11, you need to give the person your port. You can find the port in Windows Settings > System > Remote Desktop. Then, expand the Remote Desktop section.
However, Windows 11 users need to use the Remote Desktop Users panel. For that, open Windows Settings and go to Remote Desktop section. Here you can find an option called Remote Desktop users.
After that, click the Add button and enter the user account name.
Once done, click the OK button.
That’s it. Once the connection is complete, your friend will now have access to your computer and will be able to help you.
If you find that you are unable to connect, use the inbuilt Windows Network Diagnostics tool to fix the problem. If your firewall is blocking Remote Assistance connections, it will fix the problem automatically.
It’s always a good idea to close all your open programs, files, and folders before you allow remote access to your friend.
