  • How to Install Windows 11 Cumulative Updates

The Windows 11 the deployment is progressing at full speed. Microsoft’s next major consumer update – Windows 11 2022 Update (Version 22H2) – is already here available through a stable channel. However, the operating system has not been without its problems and the Redmond tech giant is well aware thereby. The company periodically rolls out updates for Windows 11 to fix bugs and introduce new features. This article will serve as a central repository of Knowledge Base (KB) articles and download links for all Windows 11 related updates.


Glossary

Windows updates are compressed in a special archive file format called Microsoft Cabinet (CAB) which supports built-in digital certificates used to maintain archive integrity. When published via Microsoft Update CatalogMicrosoft often wraps them in MSU (Microsoft Update) format.

The primary focus of this index is centered around cumulative updates (also known as monthly rollups), which include both security and reliability updates bundled together. As they are cumulative in nature, the latest patch package has the ability to update the target version of Windows to the latest version regardless of the previous version number.

In some cases, it may be necessary to apply a servicing stack update (SSU) before installing the latest cumulative update (CU). The servicing stack is the code that installs other OS updates, which is why Microsoft usually bundles them with CUs before releasing a standalone MSU package. Power users or system administrators may still prefer to deal with the CAB variant for ease of deployment. In this case, always install/integrate the SSU before committing to the CU.

Microsoft also provides CUs for the .NET Framework part of the Windows operating system. Unlike the SSU, they are distributed separately from the regular CPUs.

Windows Feature Experience Pack is another type of update that offers new feature enhancements to customers apart from core Windows feature updates.

Next come dynamic updates (DU) for the Windows installation engine. They are automatically downloaded and applied on the fly to repair Windows Recovery Environment (WinRE), installation binaries, or any file used by Windows Setup for feature updates. However, we have decided not to include them in this index to avoid clutter.

To get a clear idea of ​​Windows Update terminology, see the article on Windows Update. types of windows updates. Keep in mind that a cross-OS (e.g. Windows 10 to Windows 11) or cross-build (e.g. Windows 10 November 2019 Update/Build 18363 to May 2020 Update/Build 19041) update is a much more complex scenario. Microsoft manages these upgrade paths using the Unified Update Platform (UUP)the details of which are not part of this tutorial.


Windows 11 build index

The following indices are sorted in chronological order. Due to the fact that updates are pushed from different development pipelines, a higher KB/build count is not always the ideal indicator of the latest version. Please read the description of the update before installing.

In some cases, you may find that two or more versions point to the same knowledge base article. This is perfectly normal for state-of-the-art releases, as Microsoft is likely to assign the KB number to the latest release that will contain the aggregate fixes.

Build Number 22621 (22H2) – Windows 11 2022 Update

Activation packages

Since version .290, Microsoft has decided to split the Windows 11 22H2 beta channel into two groups. The 22622.x line is aimed at tech-savvy users, as these versions will have some advanced features enabled by default. The experimental base has been moved to 22623.x from version .730. The other set of Insiders will remain in build 22621.x, where these new features are disabled.

You can manually upgrade from 22621.x to 22622.x (or 22623.x) by installing the appropriate enabler package linked below. Note that it requires at least version 22621.285 (for 22622) / 22621.726 (for 22623) to be installed beforehand, but Microsoft has never publicly released these versions. So, as long as you’ve installed an update with a higher version number, you’re good to go.

(Optional) .NET Framework 4.8.1

As of August 2022, a standalone update for .NET Framework 4.8.1 is available for Windows 11 as well as Windows 10. Since Microsoft offers cumulative updates for .NET Framework 4.8.1 independently of the 4.8 branch, we list them in a separate index below. . The base CAB packages and offline installer are build independent, so you can install them on Windows 11 and Windows 10.

How to Install Windows 11 Cumulative Updates

CAB packages

To install a CAB update package, you must use a built-in system utility called Deployment Image Servicing and Management (DISM). The command line syntax should be as follows:

dism /online /add-package /packagepath:<path_to_cabfile>

CAB and PSF packages

Since Windows 10 Insider Preview Build 21382, Microsoft has made a significant change to the format of the latest cumulative update (LCU). Therefore, the end user cannot directly use the CAB file. To install using the built-in updater, the Patch Storage Files (PSF) must be present. This is the exact reason why PSF files corresponding to each LCU can be found in Windows 11 UUP dump. In case of online installation, Windows Update only downloads and generates PSFX payloads (PSF Express) missing, while the CAB package only contains the manifests.

However, DISM alone cannot handle PSF packages, which means we have to somehow manually combine PSF and CAB files before trying to install them offline. Fortunately, there is an open source tool named Repack PSFX for this job.

  • Extract the PSFX Repack tool archive to a folder with a short path (like “D:PSFX_Repack”).
  • Download the CAB and PSF files corresponding to the SSU and LCU and move them to the aforementioned folder. Please refer to the index above to note the appropriate KB number before downloading.
    • You can remove the hash (if any) from the filenames so that the set of files looks like Windows10.0-KBxxxxxxx-x64.cab and Windows10.0-KBxxxxxxx-x64.psf. This step is optional, as the latest version of the PSFX Repack tool can handle the new out-of-the-box naming scheme.
  • To run psfx2cab_CLI.cmd to generate the combined CAB file.

  • Use DISM to install the latest SSU CAB first, then the resulting LCU CAB file.

MSU Packages

The MSU variant, on the other hand, is somewhat standalone in nature due to the fact that you only need to double-click on it to install the package. Note that DISM can also install MSU files.

Once the installation is complete, you will be prompted to restart the PC for the changes to take effect.


Verification

The Windows 11 Settings app has an option to view the list of updates installed on your PC. Here’s how to access it.

  • Open Settings and click on Windows Update.
  • Click/tap Update history.

The good old Programs and Features applet in the classic control panel can also show you the list of installed updates.

  • Right-click Start, click To run.
  • Type appwiz.cpl and click OK. This opens Programs and Features in the classic Control Panel.
  • Click it View installed updates link on the left side. This shows you the list of updates with the installation date column.

If the command line is your thing, you can also opt for DISM or Windows Management Instrumentation (WMIC). You must run the command from an elevated instance of Windows Terminal.

dism /online /get-packages /format:table | findstr "Package_for"

We hope this article not only serves as a common update index for Windows 11, but also provides general installation instructions that may be useful for other versions of Windows as well. We’ll update this guide with links to new versions of Windows, so check back later!
