Windows: Powershell script to fix and repair WMI

6 Comments

Hi,

this script repairs and recreates the WMI Repository of a Windows. For example, this occurs sometimes if you clone a Windows machine with an installed SCCM/SMS Client. The typical error in this case is “Failed to open to WMI namespace ‘\\.\root\CCM\SoftwareUpdates\DeploymentAgent’ (8007045b)”

Lasts start. Start a Powershell console as Administrator. Stop all services. Sometimes other services depends on the WMI Service and does not accept a stop request. Therefore you cannot stop the WMI service. TrendMicro Office is such a service. You have to kill them by TaskManager.

# Stop WMI
# Only if SCCM/SMS Client is installed. Stop ccmexec.
Stop-Service -Force ccmexec -ErrorAction SilentlyContinue
Stop-Service -Force winmgmt
