How can I check whether my installation was a fresh installation or was created via a Sysprep image?

Q. How can I check whether my installation was a fresh installation or was created via a Sysprep image?


A. To determine whether an installation was created via a Sysprep disk image, perform these steps (on Windows NT 4.0 or later):


   1. Start the registry editor (regedit.exe).


   2. Go to the HKEY_LOCAL_MACHINE\SYSTEM\Setup registry subkey.


   3. If the CloneTag subkey exists, your machine was created from a Sysprep image. The value of the CloneTag subkey is the date and time that the image was created.


   4. You’ll also see a CmdLine subkey, which is the command that runs on the machine’s first start-up (e.g., “setup.exe -newsetup -mini,” which tells the setup to perform a mini, GUI-based setup).
