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
