Check if registry key exists using VBScript

Question

I thought this would be easy, but apparently nobody does it... I\'m trying to see if a registry key exists. I don\'t care if there are any values inside of it such as (Defau

Simplest way avoiding RegRead and error handling tricks. Optional friendly consts for the registry:

Const HKEY_CLASSES_ROOT   = &H80000000
Const HKEY_CURRENT_USER   = &H80000001
Const HKEY_LOCAL_MACHINE  = &H80000002
Const HKEY_USERS          = &H80000003
Const HKEY_CURRENT_CONFIG = &H80000005

Then check with:

Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")

If oReg.EnumKey(HKEY_LOCAL_MACHINE, "SYSTEM\Example\Key\", "", "") = 0 Then
  MsgBox "Key Exists"
Else
  MsgBox "Key Not Found"
End If

IMPORTANT NOTES FOR THE ABOVE:

• There are 4 parameters being passed to EnumKey, not the usual 3.
• Equals zero means the key EXISTS.
• The slash after key name is optional and not required.
