Windows 7 - Windows Update keeps failing with Error 80070216 :

Scenario:

When trying to run Windows Updates on a Windows 7, it keeps failing with the error above. You are unable to change power settings and other windows components settings either.

Resolutions:

Machine is infected with a rootkit or a virus. Download and run Kaspersky TDSSKiller, then download and run Combofix (you can google them). These two tools will clean-up your machine. Windows Update should work after that.

When you run TDSSKILLER, make sure you click on Change Parameters and check the box that says "Detect TDLFS file system".
