Windows: Windows Update does not install any updates. You’re up to date

Hi,

the situation:

Windows does not install any update and says “You’re up to date”.

I tried the following commands to investigate:

A WMI Query for all installed hotfixes return that no instance is available

1
2
D:\> wmic qfe
no instances available


Also the powershell WMI query returns an empty list

1
get-WMIObject -Query "select from Win32_quickfixengineering" empty list

Start the system file checker to resolve some issue

1
2
D:\> sfc scannow
resource protection could not start the repair service

A Cleanup image fails with an unkown command line option:

1
2
3
4
5
6
D:\> dism /online /cleanup-image /restorehealth
 
Error: 87
 
The cleanup-image option is unknown.
For more information, refer to the help by running DISM.exe /?.

The solution was the customer has disabled the “Windows Module Installer” service (trustedinstaller) for some testing purposes.

After enabling the trustedinstaller (manual is sufficant)

1
D:\> sc config trustedinstaller start= demand

all commands are running as expected and the latest updates installs..
