Download KB5003637 Offline Installer, v21H1, 20H2, & v2004

Microsoft released an offline installer for the KB5003637 update. Here are the direct links to download the KB5003637 update.

After a week’s gap, Microsoft just released a new update for Windows 10 v21H1, 20H2, and v2004. Since all three versions are the same with minor only differences, the same update is available for all three version users. While Microsoft released an optional update with quite a few fixes and quality of life improvements previously, KB5003637 mainly focuses on fixing security vulnerabilities and improving the overall security of the three versions.

Unlike the previous security update, this update doesn’t focus on a single vulnerability. Rather, it fixes and improves the security of a wide range of Windows components, files, and services. Mainly, the update provides security improvements for Windows App Platform, Windows Cloud Infrastructure, Virtualization, Kernel, Windows Storage & File System, etc.

Since this is only a security update, you don’t have to worry about any other additional fixes that can mess with your system. That being said, if the security update requires any additional updates as part of its dependency, it might automatically download a install them. However, these updates generally don’t cause any prompt. As such, I strongly recommend you to install the update as soon as possible to make sure your Windows 10 computer is fully patched.

As always, I listed below the direct links to download the KB5003637 update. Once downloaded, double-click on the file to start the installation process. Of course, you can also let Windows 10 install it automatically via Windows Update. The offline installers are useful if the Windows Update is causing problems or installing it on an offline machine.
