Question : How to grant user administrator privilage on the pc using group policy?

We have over 200 users that log in to the domain, how do we grant them access to install a program without visiting the pc and logging in with administrator privilege?

Answer : How to grant user administrator privilage on the pc using group policy?

Try this - but test it with only one or two computers in C:\Computers.txt
The hurdle I found was identifying what users were added so that they could be removed later (I'll post that script shortly).

If you're only doing one system, there's a script online that's perfect for this, if you know the exact user - because it grants admin access for a period of time (it's on a timer before they get removed).  Unfortunately that won't work here, so it requires 'two' scripts...here's the first one...

'AddAdmins.vbs
Dim objFSO: Set objFSO = CreateObject("Scripting.FileSystemObject")
Dim objOutput: Set objOutput = objFSO.CreateTextFile("C:\AdminReport.txt")

arrComputers=Split(objFSO.OpenTextFile("C:\Computers.txt").ReadAll, vbNewLine)

For Each PC in arrComputers
  Set objAdmin = GetObject("WinNT://" & PC & "/Administrators")
  Set objUser = GetObject("WinNT://" & PC & "/Users")
  For Each usr In objUser.Members
    If InStr(LCase(usr.AdsPath), "authority") = 0 Then
      objOutput.WriteLine objAdmin.AdsPath & "," & usr.Name
      objAdmin.Add (usr.AdsPath)
    End If
  Next
Next

objOutput.Close
Set objOutput=Nothing
Set objFSO=Nothing
