While updating Windows 10 PCs, some users may encounter error 0x800706d9. The most common cause of this problem is a deactivated Windows Firewall. However, sometimes it can occur due to problems with the components of the Update Center.
How to fix error 0x800706d9?
First of all, create a restore point on your computer. She will help you in case something goes wrong. Press Win + S and enter the query “Create a restore point” in the search box. In the window that appears, perform all the necessary actions and create a point on one of the disk partitions. Once done, move on to the methods below.
Method # 1 Enabling Windows Firewall
Error 0x800706d9 can occur during the Windows update process if your system has a firewall disabled. To enable it, do the following:
- press Win + S to call the search bar;
- write the request “Windows Defender Firewall”;
- click on the link “Turn Windows Defender Firewall on or off” on the left side of the window;
- select the options to enable the firewall and save the changes made;
- restart your computer and try running Windows update again.
Method # 2 Checking the Firewall and Update Service Settings
The Firewall and Update Service settings may have changed so that they stop functioning properly. Here’s what you need to do:
- press the combination Win + R;
- write in an empty line services.msc and press Enter;
- find the service “Windows Update” in the list and double-click on it with LMB;
- set the start type to “Automatic”;
- save the settings and close the service properties window;
- do all of the above for the Windows Defender Firewall service;
- restart your computer and check for error 0x800706d9.
Method # 3 Run the Update Center Troubleshooter
In some cases, you have to rely on the system troubleshooter. It doesn’t always work, but it’s worth a try. You can do it like this:
- press Win + S;
- write down “Elimination of common problems” and select the result;
- select “Windows Update” and click on the “Run the troubleshooter” button;
- follow the instructions that the product offers you;
- restart your computer if necessary.
Once you go to Windows, start the update process and check if the error 0x800706d9 has been resolved.
Method # 4 Resetting the Update Center components
If none of the above helped, we suggest that you start resetting the Update Center component. Yes, it sounds complicated, but in reality the procedure is extremely simple. Here’s what you need to do:
- press Win + R;
- write notepad.exe and press Enter;
- paste the following commands into the Notepad window:
