What are the Latest Cumulative Updates (LCU)?
Latest Cumulative Updates (LCU) are Microsoft’s way of packaging stability, security, and feature improvements into a single monthly update for Windows 10/11.
LCUs were introduced alongside Windows 10 in 2015 to simplify and improve the patch process compared to the old Windows update model. Rather than needing to install individual hotfixes, an LCU contains all fixes and enhancements from the past month.
Microsoft releases LCUs on Patch Tuesday, the second Tuesday of each month. They are mandatory updates focused on:
- Security patches for vulnerabilities
- Bug fixes and stability improvements
- Minor new features and UI changes
- Driver updates
- Previously released servicing stack updates (SSU)
LCUs are published for supported semi-annual channel versions of Windows 10/11 like 21H2 and 22H2. They bring your OS fully up to date.

For other Windows 10 builds, visit Microsoft Update Catalog page and search the KB on the search box.
Method 3: Windows Server Update Services (WSUS)
For organizations managing a large number of devices, Windows Server Update Services (WSUS) provides a centralized solution for deploying the Cumulative Update for Windows 10 Version 22H2 for x64-based Systems (KB5030211). Administrators can use WSUS to approve and distribute updates to computers within the network. To deploy the update using WSUS, follow these steps:

- In the All Updates view, locate the Cumulative Update for Windows 10 Version 22H2 for x64-based Systems (KB5030211).
- Right-click the update and select Approve.
- Select the appropriate computer group(s) and set the approval status to Approved.
- Wait for the update to be downloaded and deployed to the targeted devices.
Method 4: System Center Configuration Manager (SCCM)
To update cumulative updates using SCCM (System Center Configuration Manager), follow these steps:
- Open the SCCM console on your management server or workstation.
- In the SCCM console, click on “Software Library” in the left-hand navigation pane.
- Expand the “Software Updates” node, and then click on “All Software Updates” or “All Windows Updates,” depending on the type of update you want to deploy.
- In the Software Updates view, use the search bar or filters to find the specific cumulative update you want to deploy. You can search by KB number, update title, or other relevant criteria.
- Once you’ve located the desired cumulative update, right-click on it and select “Download.” This will initiate the download of the update to your SCCM server. You may need to create a deployment package if you haven’t already done so.
- After the update is downloaded, right-click on it again and select “Deploy.” This will open the Deploy Software Updates Wizard.
- In the wizard, specify the deployment settings such as the target collection, installation deadline, and user notifications. You can choose to deploy the update immediately or schedule it for a specific time.
- Once the deployment is initiated, you can monitor its progress by checking the “Deployment Status” node in the SCCM console. This will show you the status of the update installation on client machines.
SCCM will use its distribution points to distribute the update files to the client computers and initiate the installation process based on the deployment settings you configured. The clients will download and install the cumulative updates according to the schedule or deadline you specified.
Note: It’s important to thoroughly test cumulative updates in a non-production environment before deploying them in a live production environment to ensure compatibility and avoid any unexpected issues.

Open Command Prompt with administrative privileges: Right-click on the Start button, and select “Command Prompt (Admin)” or “Windows PowerShell (Admin)” to launch the Command Prompt with administrative rights.
#1. Run the command to analyze the component store:
dism.exe /Online /Cleanup-Image /AnalyzeComponentStore
This command analyzes the component store and provides a report on the size of the component store and the potential disk space savings that can be achieved by running cleanup operations.
#2. Run the cleanup commands mentioned earlier:
DISM.exe /Online /Cleanup-Image /StartComponentCleanup
This command cleans up the superseded and unused system components from the Windows Update repository. It helps to reclaim disk space by removing unnecessary files.
#3. Perform a Windows Update cleanup:
DISM.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase
This command combines the functionality of the previous command with an additional step that removes all superseded versions of every component in the component store. This action cannot be undone, so it’s important to ensure you have all the necessary updates installed and your system is stable before proceeding.
