win32_process type name not found in system.management.managementc

I am new to powershell and was trying to use powershell to install/uninstall
services on a remote machine. the command i was using to create a
win32_process is:

PS C:\> $mc = new-object system.management.managementclass
\root\cimv2:win32_process

This command was working fine untill earlier today and i was messing around.
I found out that i executed this line:

PS C:\> $mc.delete()

and now when i try to create a new win32_process i get this exception:

New-Object : Exception retrieving the type name hierarchy: "Not found ".
At line:1 char:11
+ new-object <<<< system.management.managementclass \root\cimv2:win32_process

This is really weird, has anybody seen this before? i dont know what to do.

Thanks for the help.

You did remove the win32_progress CLASS from the WMI repository.

one option is to stop the WMI service and delete the following directory :

%windir%\system32\wbem\repository

and restart WMI service, the repository will be re-build again

or you can just re-compile the cimwin32.mof file to add the classes in there
again

the first option is a bit more brute-force but easier without the WMI
knowledge

It worked. I have another quick question for you. I am using powershell for
automation and after i uninstall the windows service how can i delete the
..exe file afterwards?

Thanks again for the help /\/\o\/\/

I forgot to add that I am doing on a remote machine from a build server.

I can not give a faultproof solution, becouse of the way services work :

there is a way to list the exes called directly, but it would only work for
Own Process services and for the command that get's invoked

gwmi win32_service | group ServiceType

to find out and list startup path for all 'Own Process' services :

gwmi win32_service |? {$_.ServiceType -eq 'Own Process'} | ft name,pathname

look for youself if this will work in our case

h.t.h.
