First things first: As expected, the SKU vs. Edition distinction that I called out in part 1 was somewhat contentious with some people. I used the terms somewhat interchangeably through the article. The “most correct” term would be “edition” but “SKU” is well understood (and not just by Microsoft people). Even Microsoft documentation is inconsistent on this:
- OperatingSystemSKU Enum from the PowerShell SDK uses “SKU,” not “edition.”
- OperatingSystemSKU from the WMI Win32_OperatingSystem class also uses “SKU,” not “edition.”
- Windows 10 edition upgrade documentation uses both “edition” and “SKU” in the same article.
- Windows IoT Licensing & Usage documentation uses “SKU.”
- Windows 10 in S Mode talks about how it replaced the original Windows 10 S “SKU.”
You get the picture — as long as you don’t get too hung up on the slightly-incorrect usage of “SKU” and realize that it’s just the “edition” of Windows that you are running, you’ll be fine.
But what I want to focus on in this article is something that will use yet another term for the same thing: the product type. If you look at the GetProductInfo API call documentation, you can see that it returns details about the OS edition (a.k.a. the SKU) in the pdwReturnedProductType field. That’s similar to the OperatingSystemSKU fields mentioned in the PowerShell SDK and WMI class docs above, although as is often the case with Microsoft docs, you will see a different list of OSes in each place — and none of the lists are complete. So where’s the “master list”? It’s in the Windows SDK files, more specifically the “winnt.h” file, which also (not surprisingly) uses “product type” values:
This file lists every Windows edition (SKU) ever created, including some that were never released. While I suppose it’s possible that some entries have been deleted from the list, I don’t know of any examples where that has happened. It’s also possible that there are new values not yet visible in the latest SDK release, which at this time is the 10.0.20344 SDK release.
So the real exercise is to map the SKU values in the winnt.h product list to the editions (SKUs) from the previous blog, then look at the resulting list to see which aren’t represented, which would mean that they aren’t covered in the Wikipedia blog posts that I was pulling from (which in turn represent “official” SKUs). Some of these do exist, while others represent a “graveyard” of Windows editions that could have been.

Hmm, I don’t recall seeing any “Medium Business Server.” But given its place in the numerical sequence, this was quite some time ago.

No idea what these “V” SKUs are all about. Maybe tied to virtualization?

Looks like more SBS-like SKUs (still not sure if they were ever released).

These I at least remember: They were editions (SKUs) of Windows 7 created in response to the European Union’s Internet Explorer complaint. They remove Internet Explorer from the OS, which broke various things. And as with the G and K SKUs, they were the same cost as the non-E SKUs, so no one really wanted them. (Best of intentions…)
#define PRODUCT_MULTIPOINT_STANDARD_SERVER 0x0000004C
#define PRODUCT_MULTIPOINT_PREMIUM_SERVER 0x0000004D
This is one that I thought should have caught on: Multipoint Server. The idea was that you could have one PC with one or more video cards in it, driving multiple sets of keyboards, mice, and monitors. VDI and thin clients ended up winning out, and these slowly faded away.

You can’t forget about the evaluation editions, which are still available. While you can’t turn Windows 10 Enterprise Evaluation into a full release, you can do that with the server editions (SKUs).

There have been a variety of Embedded variations, including for automobiles.

“Core Connected” SKUs came out around the time of Windows 8.1 I believe. They were similar to Windows 8 (Core) but were designed to run in more of a “cloud-only” environment. Maybe a little before their time?
#define PRODUCT_PPI_PRO 0x00000077
Before there was Surface Hub, there was Perceptive Pixel (PPI), the company that Microsoft bought. These ran a variation on Windows (8.1?) Professional, similar in some ways to the Windows 10 Team SKU that took its place.
#define PRODUCT_ARM64_SERVER 0x00000078
From the assigned number, this one has been around for a while, even though it’s not yet been released. But I believe this will be released at some point. If you’re wondering where ARM64 is likely to succeed first, it’s most likely in the server space (as Amazon has already found out), not in the desktop space (unless you’re Apple).

The “_S” SKUs are the Long-Term Servicing Channel (Branch) releases. As you can see, there were some thoughts initially about having an LTSB/LTSC release for Windows 10 Pro. Fortunately (well, at least I thought it was fortunate), that never happened.
#define PRODUCT_HOLOGRAPHIC 0x00000087
#define PRODUCT_HOLOGRAPHIC_BUSINESS 0x00000088
Hololens devices have their own OS, the only OS to be released (so far?) based on the Windows Core OS, capable of running on UWP apps, not Win32. The “Business” edition added MDM, Azure AD Join, etc. features. (I initially forgot these in the previous post, will get them added shortly.)

Initially I thought these were yet another take on a Windows “Cloud” release, but no, these are actually Windows 10 S (before it became S Mode).
#define PRODUCT_LITE 0x000000BD
I would consider this to be Windows 10x (RIP?), another Windows Core OS-based OS release that was first for low-cost devices, then dual-screen devices, then single-screen thin client devices, then “de-emphasized.” Will it ever return? Who knows.
See any other OSes in that list that you didn’t recognize? It is quite the list. Imagine what the diagram in the last post would look like if you added all of those variations into the mix. I have no great desire to tackle that at the moment, maybe some day when I’m bored…
