List of free-form strings that an OEM defines. For example, an OEM defines the part numbers for system reference documents, manufacturer contact information, and so on.

I was looking for a simple thing that would let me know the number of stored user profiles on the system. It’s something that had come up before and there was a property that looked promising, Win32_OperatingSystem.NumberOfUsers, but it wasn’t. So I started poking around looking for stuff.

When the following code is run against a VMWare machine it returns the following tidbit of information.

strComputer = Vmware-pc
Set objWMIService = GetOBject(winmgmts:\ & strComputer & rootCIMV2)
Set colItems = objWMIService.ExecQuery(SELECT * FROM Win32_ComputerSystem,,48)
For Each objItem in colItems
Wscript.Echo OEMStringArray:  & Join(objItem.OEMStringArray)

OEMStringArray: [MS_VM_CERT/SHA1/lotsoflettersandnumbers],Welcome to the Virtual Machine

I don’t know about you, but I couldn’t stop singing Pink Floyd – Welcome to the Machine!
