Microsoft has released the optional KB5037849 Preview cumulative update for Windows 10 22H2 with nine fixes or changes.

This release is primarily a maintenance release, fixing numerous bugs causing crashes or network connection issues. However, Microsoft released two new enterprise features and improved Chinese fonts and input.

This cumulative update preview allows Windows admins and users to test upcoming fixes and features that will be released in the following month’s mandatory Patch Tuesday. Unlike Patch Tuesday cumulative updates, the preview updates do not include security updates. 

Windows users can install this update by going into Settings, clicking on Windows Update, and manually performing a ‘Check for Updates.’

As this is an optional update, you will be asked whether you wish to install it by clicking the ‘Download and install’ link, as shown in the image below.

After installing this update, Windows 10 22H2 will be updated to build 19045.4474.

Windows 10 users can also manually download and install the KB5037849 preview update from the Microsoft Update Catalog.
