Whether you’re managing a single PC or hundreds of enterprise PCs, the challenge has always been a headache if you want to install monthly patches in a timely manner and prevent updates from damaging Windows itself. It is well known that Microsoft has mandatory cumulative and security updates that are delivered on the second Tuesday of each month. Microsoft’s Windows 10 patch, released Tuesday, also includes service stack updates, compatibility updates, and Windows Defender patches.
Microsoft says service stack updates should be installed before other updates because they may contain critical fixes to the components that manage the Windows Update process on the device.
The service stack also contains a “component-based service stack,” which is a key component of several Windows 10 features, such as SFC (System File Inspector), DISM (Deploy mirroring services and management), and other command-line-based features.
As we mentioned above, Microsoft “strongly recommends” that users install their latest service stack updates before installing monthly cumulative updates.
Traditionally, SSU has released periodic updates every once in a while to update Windows’ software stack. The fixes included in the SSU are necessary for the reliability of the update process or to address issues that prevent Windows 10 patching. If you do not install SSU, you may experience problems installing future Windows updates.
SSU is available separately, but starting with the September 2020 cumulative update, Microsoft says it will eventually combine the SSU with the latest cumulative update into a “single package design.”
By combining SSU and LCU, Microsoft wants to address issues that users experience with Windows updates and provide a “seamless installation experience.” This change will apply to your PC after you install Windows 10’s September service stack.
Microsoft said this month’s SSU was also automatically available and did not need to restart the system. To get updates, go to Windows Update Settings and check for updates.
