Hi, I noticed in VLSC that KMS key for win2008r2 standard and enterprise are identical, Why? Is this the norm? Tnx

Hello, I dont think so. There are three Groups of KMS keys coving all Windows Server 2008 R2 products. A Windows Server 2008 R2 Datacenter KMS key is a Group C key while a Windows Server 2008 Standard KMS key is a Group A key.
