Change Windows 7 Serial Number

I want to make a little Licene Management with C#.

With a common PC-Image, i set up some workstations without a serial number and then I want to change the serial number with a c# daemon.

My questio开发者_开发问答n: how can I change the serial number and activate windows 7 using C#?

Thank you!

You're looking for slmgr.vbs.
You can call it using Process.Start.
