Renaming article
[edit]Since Microsoft now uses the term "OEM Activation" instead of "System Locked Preinstallation", I think that this article should be renamed and a redirect created.--216.254.123.206 (talk) 00:13, 18 August 2008 (UTC)

[edit]The keys are not copyrighted (they are a fact), and they aren't DMCA circumvention devices. There is no copyright violation here per Talk:Volume license key. 68.173.145.85 (talk) —Preceding undated comment added 17:09, 15 January 2010 (UTC).
Besides, these keys are given by Microsoft themselves. They are public knowledge, and will only work with proper media. Now if I were to explain how to convert OEM windows 7 into better versions for free, that would be discussion of copyright violation. But I'm not gonna do that.74.211.59.62 (talk) 23:06, 6 August 2011 (UTC)
Exactly. these keys are legit. The windows XP keys only work with SLP media and a SLP bios. The other ones are trial keys, that allow installation until you can get your proper key. This is often needed when upgrading OEM windows 8.0 to 8.1 by installing from media (because the windows store is broken for you). the installer will not accept OEM keys from the bios, so you will need to enter the placeholder key to get the installation going, and retrieve the actual key from the bios later. 74.211.59.182 (talk) 01:27, 8 November 2014 (UTC)
Personal Experience
[edit]I can verify all of the information mentioned in the article through personal experience. In addition, I would like to comment that Microsoft still refers to this method as SLP which is evident in the Windows 7 licencing verification method. This can be viewable by software designed to verify product keys using pidgen.dll and other internal Windows files. Kamron Batman (talk) 09:13, 25 April 2011 (UTC)
Disputed - Possible issue with NSLP description
[edit]I came across the following statement in the "Non System Locked Pre-installation" section:
"The product key is added into the machine's firmware, but is not locked to it and can be moved to other machines."
I am not sufficiently familiar with the historical OEM licensing terminology to make the correction myself, but I think this statement may be conflating OEM with OEM Activation 3.0 / OEM.
Microsoft's documentation describes OA 3.0 as the mechanism in which an OEM product key is injected into firmware (ACPI MSDM) and associated with a particular computer. OEM:NONSLP appears to be a distinct licensing channel rather than simply a firmware-embedded key that is transferable between machines.
Could someone familiar with Windows OEM activation/licensing terminology verify this statement against reliable sources and correct it if necessary? In particular, I would like to know whether an OEM:NONSLP key is actually intended to be stored in firmware, or whether the firmware-key description belongs specifically to OA 3.0 / OEM:DM.
