Using SetupComplete command through usb?

[JatinXXX]

I m installing W7 from usb. How to run a command after setup completes from usb i.e. first logon. Thanks in advance.

I need to install cert.xrm-ms. and the command i needed to run at first boot is slmgr.vbs cert.xrm-ms/ilc.

No you don't. Can instead just copy your XRM-MS here in your OEM folders and Windows will find it.

DVD\Sources\$OEM$\$$\System32\OEM\cert.xrm-ms

If the cert file is in that folder, then Microsoft will find it and use it.
