I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The commands, you enter in the Run Once, are the Operating System (Windows) commands or scripts you write, which are entered into the Run Once Key in the Windows registry.

The Run Once commands are related to Microsoft Sysprep

At Windows startup, these commands are executed in the Windows OS, these could be Windows powershell commands.

These are NOT VMware commands.
