Then issue the command slmgr –ipk 2QTV2-3CMPP-FQBYK-XXXXX-XXXXX (For windows 7 Pro) So issue the command slmgr –ilc c:\temp\dell-dell-2.0.xrm-ms The certificate is called Dell-Dell-2.0.xrm-ms Open an elevated command prompt, extract the Dell certificate to C:\temp To use this, for example if you had a Dell. When you rebuild a PC component 1 is still present but #2 and # 3 are missing.Īttached in the SLIC.zip file you will find the certificate files used by Major OEM’s such as Dell, HP, Lenovo, as well as product keys that can be used for Windows 7 Professional, and Ultimate. If all 3 are present the system is instantly activated, does not communicate with MS to determine if activation is valid or to activate against a MS server. These keys are not specific to a particular OEM and are interchangeable. A Windows product key that tells the system to use OEM activation instead of the traditional Microsoft activation process.These certificate files are unique to each OEM so Dell has their own, HP has their own, etc. A certificate file that matches up against the “SLIC” string that is stored in the BIOS.Home built systems will not (unless you modify the bios yourself) The bios of the system must contain what is called a “SLIC” string, all systems made by a major OEM such as Dell, HP will include this.In windows Vista, 7, server 2008, 2008r2, and server 2012 OEM activation is accomplished by the combination of 3 elements. I recently came across a system that had been rebuilt and the activation was not re-applied so after 90/120 days the system started reporting it was not genuine and realized a few of you may not know how to re-apply OEM activation.
