I thought I would ask here as people seem to be familiar with how this rather niche OS works. I know that Windows 7 (and Server 2008 R2) have three main activation methods: 1. Standard retail "FPP" authentication with Microsoft. 2. Volume license "VOL" with MAC or an internal KMS server. 3. OEM license "OEM" which seems to check computer BIOS information. These may not be 100% accurate as I am still learning about the overall process. Now, Windows 7 Embedded has a fourth method very similar to the old Windows XP VOL licenses where a key is entered and the OS appears to be locally activated in a permanent method. What exactly is done differently with this OS compared to the others? Therefore, my question is, is Windows Embedded Standard 7 similar in that it has files dealing with licensing/activation that are different or is this built closer to the kernel somehow? Some forum posts mention converting between retail "FPP" to "VOL" copies by replacing certain files. However, the files replaced already came from the VOL version of the OS. Thanks!
