Windows 7 to Windows 10 Fall Creators Update (1709) In-Place Upgrade Fails with error 0xC1900204 (Invalid Sku)

We have built an SCCM In-Place upgrade task sequence to migrate our enterprise from Windows 7 Enterprise to Windows 10 Enterprise. We have been using the same basic TS for over a year without issues. With the release of Windows 10 Fall Creators Update (1709), we began having issues upgrading certain devices and were seeing error code 0xC1900204, indicating Invalid SKU.

Windows setup looks at the existing OS, install media and the command line image number to validate that the existing and desired versions are a match and can be upgraded. The new multi-version install media that came with Windows 10 Fall Creators requires more steps (behind the scenes) to make the match and seems to have issues with some systems. I’m not sure how relevant this is, but we are using KMS keys for all of our devices.

Let’s take a look at the setupact.log from a failed client to see some snippets of these steps.

Here we can see the command line that is dynamically generated from the Upgrade Operating System step in your TS (See image at the bottom of this post).

After digging through this for a bit, I learned some things that I didn’t know. The PidGenX and Digital Marker lines are where I found the root of the problem. I honestly could not find any real useful information about PidGenX, but I believe that it’s a product ID checking utility. For some reason it fails. As I mentioned before, we are using a KMS key, so it’s possible that it has issues communicating to my KMS server, but I’m just not sure.

The Digital Marker on the other hand refers to the OEM SLP in the MSDM ACPI table in UEFI, or the System Locked Preinstallation (SLP) key in the Microsoft Digital Marker (MSDM) in the Advanced Configuration and Power Interface (ACPI) table embedded in the Unified Extensive Firmware Interface (UEFI).

Once I started looking in the right place, I was able to find the Digital Marker on my devices using a tool called RWEvertything with the assistance of this post. I confirmed that my machines all had OEM Professional SLP keys instead of Enterprise (also, it said it on the sticker on the outside of the machine!!).

From there, I contacted Microsoft Premier Support and they suggested adding the KMS key to the Product key field in my TS using the correct KMS key from Microsoft here.

Once I added the KMS key in, the upgrades started working again. While the workaround fixed the issue, I’m just not sure if this is a bug, underlying issue with my environment or just Gremlins. It would be great to know someday.
