Method 1: Using tdsskiller.exe to remove rootkit files

Method 2: Disabling firewalls and antiviruses
If you used tdsskiller.exe without results, let’s determine if your 3rd party antivirus suite or firewall is not acting up. Third party firewalls or antivirus suites can malfunction and determine that the Windows update connection is unsafe. This will end up preventing your Windows OS from applying the necessary updates. There are a lot of conflicts between Windows Defender and 3rd party security solutions that will produce the 80072EFE error. Here’s a list of firewalls that are known to cause this issue:
