Let’s discuss Windows Updates Ramblings SSU WUA UUP CU WaaS SCCM, and Many More. I find recent changes to the Windows update mechanism most confusing.

I am having trouble understanding the recent changes to the Windows update mechanism. It seems like many new terms and components are being introduced, such as Windows Updates Ramblings, SSU, WUA, UUP, CU, WaaS, and SCCM.

The recent changes have made understanding Microsoft’s strategy for Windows 10 updates quite challenging. It requires time and effort to find clear information about how these different components work together and the overall strategy.

In this post, I will share some tips about service Stack Updates, Windows Update Clients, and other related topics (SSU WUA WaaS UUP).

Patch My PC

Windows Updates Ramblings SSU WUA UUP CU WaaS SCCM

I’m sure you might be wondering about the difference between SSU, WUA, UUP, and CU updates apart from Windows 10 feature updates.

Another confusing term in the Windows Updates world is WaaS. The post below provides more details about WaaS.

  • SSU – Service Stack Update. These are Critical updates.
  • WUA – Windows Update Agent/Windows Update Client
  • CU – Cumulative Update
  • UUP – Unified Update Platform (limited preview)/Express Content

Data Points

Let’s see more details about SSU WUA, UUP, and CU.

WUA (Windows Update Agent)

Data Point #1 – The WUA is a subset of the SSU. (Thanks to Bryan, check the link to the post below). SSU is designed to update the Windows updating software itself.

More details on SSU and WUA – Excellent Post from Bryan Dam

SSU (Service Stack Update)

Data Point #2 – The SSU updates WUA, and all things around servicing changes to the Windows endpoint. (Thanks to Jay for the clear explanation)

NOTE! – SSU & LCU are part of the Windows Cumulative update. I will share more details in a future post about the Windows update.

Data Point #3 – SSUs are considered a pre-requisite and recommended (even if not enforced via metadata on newer Windows 10 versions) before installing CUs—more Details from Microsoft Documentation.

UUP (Unified Update Platform)

Data Point #4 – Does UUP help simplify all the above complex scenarios, or is it more related to the “Delivery mechanism” overall Windows update experience? More details about UUP. Microsoft is still working to improve the UUP experience with some customers as per the KB article 4512745.

NOTE! The unified update platform (UUP) is a one-stop shop for all your Windows Update content. It’s available for Windows Business for Update (Intune) and is coming soon for SCCM and WSUS.

Data Point #5 – Are you confused about SSU and SCCM-related restarts? Read through the commentary by Scott Williams.

Data Point #6 – Install a Windows 10 SSU before the LCU using SCCM, an excellent post by MVP colleague Mike.
