Delete Folders using WMI

[Babu VT]

Hi,
I'm trying to clean "$NTUninstall..." folders from remote machines and found
the below snippet useful.Unfortunately it isn't deleting any folders.Can
someone point me where is the fault... I can't use FSO objects since I need
to delete folders in multiple machines where C$ shares might not be
available.

strComputer ="."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
strQueryString1 = "Select * from Win32_Directory where Name = '" &
OSRootDir & "'"
Set colSubfolders = objWMIService.ExecQuery (strQueryString1)
For Each objFolder in colSubfolders
If Instr( UCase(objFolder.Name), "$NTUNINSTALL" ) > 0 then
strReport = strReport & "Deleted :" & strcomputer & ":" & objFolder.Name
& " uninstall folder" & vbCrLf
objFolder.delete
End If

Next

You need to assign a value to OSRootDir, e.g. "c:\\Windows". Alternatively
this Scripting Guy item might help:
How Can I Delete a Folder and All Its Subfolders?

Rather than just deleting the uninstalls, I prefer to check the age of
the folders just to be sure it is safe to remove them. That is why I
wrote the following which will only delete the folders if they are more
than 2 weeks old.

Just realized the posted version had the two week check commented out.

Sorry for the repost, but I noticed I had the date checks commented out
on the previously posted version.
