Q: Is Quick Assist safe?

"Because of some damaged files that cannot be repaired automatically, I took the initiative to contact Microsoft for technical support. He replied to me that he can run some diagnostic programs by remotely accessing my computer, so I used Quick Assist and granted him permission.

He changed some content in the boot menu and then restarted. Everything seemed to be normal, but afterward, I felt that my privacy was a bit infringed. I tried to delete the program he used, but it did not show up in the control panel. Now I want to ask, is Microsoft Quick Assist safe and secure?”

A: Quick Assist is secure

Quick Assist, a free function based on the Remote Desktop Protocol (RDP) communicates through port 443 (https) and connects to the remote assistance service using RDP. It allows the facilitator to remotely connect to the assisted person’s computer. And the traffic is with TLS 1.2, which keeps data being transferred across the network more secure.

In the process, you will neither expose the IP address, but also hold the initiative of remote assistance; and you can monitor all operations of the other party during the session. Obviously, there is no need to worry about the security of using Quick Assist.

How to set up Quick Assist?

After confirming that Quick Assist is secure, you may wonder how to set up it for getting help next time.

Next, I will give you a detailed introduction to the Quick Assist setting method. Take you as a technician and provide remote technical support for othersas an example:

Before you start, make sure the following things:

  • Both computers connected with Quick Assist need to ensure that the Windows 10 version is 1607 and above.
  • Communicate with the technicians to confirm the identity of the other party.
  • If you are a professional providing remote technical support, you must have a Microsoft account, please register an account firstly and use Quick Assist if you do not have the above account.

Step 1. On your computer, search “Quick Assistance” in the search box.


Step 2. Find "Give Assistance" in the opened window, and then click "Assist another person" below.


Step 3. Then a window will automatically pop up, enter the corresponding email or phone number (you can also use it if you have a Skype account), and click "Next".


Step 4. Then enter the password corresponding to the Microsoft account and click "Sign in".


Step 5. Then you will get a security code valid for 10 minutes (if the security code expires, you can click "Cancel and restart" to get a new security code).


Step 6. On the computer that needs remote technical support, open the "Quick Assist", enter the security code of the remote assistance computer in the main interface of the window, and click "Share Screen".


Step 7. Choose "Full Control" or "View Screen", and then click "Continue".


Step 8. On the computer that needs remote technical support, click "Allow" in the "Share your screen" pop-up window to realize remote assistance between two Windows 10 computers.


Step 9. Now you can give assistance to the remote computer

Note: You can refer to the above steps to provide or seek remote technical support.

If you are still worried about the safety of Quick Assist, read the following to learn how to improve the safety of Quick Assist.

How to improve the safety of Quick Assist?

Actually, it is safe enough if you are using Quick Assist, which means that there is not much room for improvement in safety; if you are still worried about safety issues, you can further improve safety through the following three methods:

Method 1. Use VPN

Virtual Private Network (VPN) is one of the best ways to protect your computer from cyber-attacks. Using it means that before accessing your computer, you must first connect to a secure private network, which is usually encrypted and hosted outside of your server, so the secure connection itself does not require any of your server resources. More importantly, when using a VPN, the server is configured to only allow connections from the VPN address, thereby rejecting any access requests from external IP addresses.

Method 2. Use a hardware firewall

Since Quick Assist uses port 443 to connect to Microsoft-supported servers, this means that it will bypass most existing firewalls and network address translation protocols (NAT). Therefore, you need to use a hardware firewall to improve security.

Method 3. Confirm the identity of the other party

Since the assisted person can use Quick Assist without logging in or verifying credentials, it means that you cannot be sure who accessed your computer or where you are accessing your computer. Therefore, confirm the remote technology before using Quick Assist.

It can realize remote assistance without a Microsoft account, and the secure connection code used has no time limit, and the operation is simpler in comparison. In addition, AnyViewer also has the function of unattended access, which is more convenient to use. Next, I will give you a detailed introduction to the realization of remote assistance on Windows 10 through AnyViewer.

Is Quick Assist safe? I can tell you with certainty that it is safe if you are sure that the one who provide you with remote technical support are trusted professionals. Of course, you can further improve the security of Quick Assist by using VPN, hardware firewall, and confirming the identity of the other party.
