How to fix Windows apps update error 0x800706d9?

Issue: I can't update Windows. It stops somewhere in the middle, saying that an update error 0x800706d9 has occurred, and the process could not be completed. I tried rebooting the system and waiting, but there were no positive results. Any tips?

Solved Answer

An error 0x800706d9 can appear on your system whenever you manually initiate the application update process, although those who use the automatic update function can also notice that it has failed. As a result, users are left with being unable to update any applications via Microsoft Store and sometimes can't even download new ones.

0x800706d9 error might show up due to interferences between a system update and Windows Firewall. This integrated application proof-checks the in-and outgoing applications. It is likely that some registry issues appeared in the latter program. Therefore, installation of the newest updates might fail.

Fortunately, there is a way to solve the problem and continue with the update procedure. In addition, you might notice another issue related to this one. Along with the 0x800706d9 error message, Windows firewall error 0x6D9 code notification might show up as well. We will provide solutions to both of these problems.
