So, I have been looking for an OEM Key for Server 2012 R2 Essentials and can't seem to find one. Neither here, in the "Windows Server 2012 & 2012 R2 OEM SLP Keys" thread (or elsewhere on the forum), and it appears that Daz' Loader doesn't have a key for 2012 R2 Essentials, either. I have a Dell PE 2950 that I have modded the latest BIOS w/ SLIC 2.3 on. I have the Dell BIOS SLIC table installed and I have the Dell Cert, but I can't find an OEM key for 2012 R2 Essentials. Before everyone jumps in with helpful suggestions to simply go with the Toolkit and emulated KMS, I did that (and it worked... Thanks!), but since I took the effort to mod the BIOS and I have the Cert, I'd love to try and get Server 2012 R2 Essentials up and running "clean" with a fully OEM install. It seems like the "Windows Server 2012 & 2012 R2 OEM SLP Keys" thread has OEM keys for almost every different flavor of Server 2012, other than 2012 R2 Essentials. There are keys for 2012 Essentials (NOT R2) and keys for 2012 R2 (Standard, Datacenter, etc.) but not 2012 R2 Essentials. I did try a couple of those keys for different versions just to see and, not surprisingly, none of them worked. Somebody has got to have an OEM Key for Server 2012 R2 Essentials, no? Am I missing something? A p.m. would be great, if we're not posting OEM keys anymore. Thanks in advance!
