What is LCU / SSU

Oh thanks, is it possible not to use these abbreviations on the website?

Another question in this regard. It states that you have to install the SSU before the LCU, but does the LCU include this SSU, and for the next months will this SSU be valid to install before the next LCU because I have missed it in March or April?

What is LCU / SSU

As described in the recent 2 update histories, Microsoft Team can you please elaborate what is SSU and LCU? (Guess: SSU is Servicing Stack Update)

I cannot find a reference for this. Thank you in advance

Important When installing both the SSU (KB4093432) and the LCU updates from the Microsoft Update Catalog,
install the SSU before installing the LCU.

Deploy Windows 10 SSUs and LCUs together with one cumulative update

You can now deploy the December 2020 latest cumulative update (LCU) and servicing stack update (SSU) together via our new one cumulative update package, or separately.

On September 9th, 2020, I announced the work in progress to simplify on premises deployments of servicing stack updates. Today, I am excited to announce that you can take advantage of this new capability using Windows Server Update Services (WSUS) and the Windows Insider Program for Business.

We have released the December 2020 LCU and the December 2020 SSU to WSUS in two ways for devices running Windows 10, version 2004 and later: to the typical Security Updates category and to the Windows Insider Pre-Release category.

To deploy the cumulative update and servicing stack update separately, no special action is needed. Just ensure, as always, that you deploy the SSU prior to deploying the LCU so that both updates install successfully on the device.

To deploy the LCU and SSU together using the new one cumulative update package, simply follow three easy steps.

Note: Before completing the steps below, ensure that you have installed the September 2020 SSU on the targeted devices.

Step 1: Sync the Windows Insider Pre-Release category

In the WSUS console, from Products and Classifications, select Windows Insider Pre-Release Product and Upgrades. Sync WSUS.

In Microsoft Endpoint Manager Configuration Manager, navigate to the Products tab of
Software Update Point Component Properties and select Windows Insider Pre-Release. Select OK to confirm this selection.

Step 2: Select the OS version

From the list of All Updates, select the cumulative update for the version of Windows 10 running on the device(s) that will receive the update. Currently, this would be either of the following:

2020-12 Cumulative Update for Windows 10 Version 2004

2020-12 Cumulative Update for Windows 10 Version 20H2

Step 3: Deploy the update

Deploy the update to the desired devices in your organization the same way you would deploy any other monthly cumulative update.

Note: When you deploy the update package to your devices, the client will automatically orchestrate the proper ordering of installation to ensure the SSU and LCU are both applied correctly on the device. This will be the exact same content as if you had deployed the December 2020 LCU and SSU separately.

Check your preferred method of reporting and note that your devices are now running the December LCU (KB4592438) and SSU (KB4593175).

That’s it! It’s that simple.

The best part? Like all preview builds published to commercial devices in the Release Preview Channel and to the WSUS Windows Insider Pre-Release category, testing out this new deployment technology for LCUs and SSUs from WSUS is fully supported.

If you run into an issue that prevents you or other users in your organization from deploying or updating using this new one cumulative package, use this online form to request assistance directly from Microsoft Support at no cost to you. Or contact customer support through your typical channel.
