Trouble with Factory Settings restoration! (

I recently received assistance from an Alienware tech support. After taking control of my computer remotely, the tech specialist was unable to resolve my original issue (a registry cleaner deleted Alienware files, corrupting Command Center). He recommended I restore my computer from factory settings. When I asked about using AlienRespawn he said it may leave traces of my current settings, which may leave the problem unresolved. He recommended I do a restore using the windows 7 disk I received with my laptop, which I did without a problem. The restore did fix the command center error (after reinstalling dozens of drivers and programs) but now I do not have many programs that my computer came with. I lost the following, and probably more: AlienRespawn, Alienware start and shut down screen, Alienware log-on screen, webcam utility, and more. Basically I now have a dell computer with Alienware hardware that I cannot utilize. How can I restore my laptop to ALIENWARE FACTORY settings, as I received my laptop, as opposed to DELL FACTORY settings?

Thanks for your help, if you own an Alienware computer you know how important it is to have the Alienware utilities and streamlined appearance that the price warrants.
