If you have deployed an operating system to a system with System Center Configuration Manager 2007 (SCCM 2007), the task sequence is still being advertised to the computer. This means that a user is able to open the “Run Advertised Programs” window and re-run the Operating System Deployment. This may lead to unwanted situations, i.e. when a user accidentally runs the deployment, while he has important files stored locally.
There is no way to hide the Operating System Deployments from being advertised to “normal” users, but there is a workaround. You can set the OSD to run only on a specific OS. Then you would select an OS that you don’t use in your organization.
With this setting, an OSD will not be advertised to a user while working on the computer. However, you will still be able to re-image the system using PXEboot or USB boot (booting to WinPE).
