There is a great change made to how Microsoft is delivering update to WSUS and the Windows Update catalog. Instead of supplying the separate servicing stack update (SSU) and latest cumulative update (LCU) packages, the company is merging them into a single package, available on Microsoft Update Catalog, and for the WSUS.
Currently, to keep devices up to date, IT administrators who manage devices using on-premises methods must select and deploy the correct servicing stack update (SSU) with the latest cumulative update (LCU). In some cases, a specific version of the SSU must already be installed in order to install the latest LCU. If the device in question does not have the required SSU already installed, the LCU will fail to install.
The error message that the LCU failure can produce, "update isn't applicable," doesn't make the root cause immediately apparent.
This issue doesn't affect regular consumer devices. With the Windows Update experience where the SSU and LCU are deployed together to the device. The update stack automatically orchestrates the installation, so both are applied correctly.
Starting in September 2020, customers will be able to follow these new scenarios.
- Searching for both the SSU and LCU KB articles. All release notes and file information for monthly cumulative updates, including those related to the servicing stack, will be in a single KB article!
- Determining if this month's LCU has a dependency on a specific SSU version or newer and ensuring that the right SSU and LCU are deployed and installed in the correct order. The SSU and LCU will be packaged together, and the client will orchestrate the installation. Select the monthly cumulative update you want to deploy, and we will take care of the rest!
- End users confused at seeing multiple servicing releases in a month. The Window Update Settings and History pages will now look the same as it does for those who update from the cloud today!
To move forward with receiving a single monthly cumulative update package containing the SSU and LCU, you will first need to broadly deploy the September 2020 SSU or any later SSU on all Windows 10, version 2004 devices in your organization.
