Windows 11 KB5012592 Update Brings Default Browser Improvements

Microsoft has released Windows 11 Cumulative Update KB5012592 with security updates, quality improvements, and a fix that makes it easier to switch default browsers.
KB5012592 is a required cumulative update because it contains April 2022 Hotfix Tuesday security updates for vulnerabilities discovered in previous months.
Windows 11 users can install today’s update by going to To start up > Settings > Windows Update and clicking on ‘Check for updates.’
Windows 11 users can also manually download and install preview update KB5012592 from the Microsoft Update Catalog.
It is now easier to change the default browser
Cumulative update KB5012592 includes a fix for a controversial change that made it difficult to change the default web browser.
When Windows 11 first came out, it no longer included a button you could click to change your default browser.
Instead, Windows 11 users had to perform the tedious task of finding each file extension (.html and .htm) and protocol (HTTP or HTTPS) and manually associating them with the program they wanted to use.
With the KB5012592 update, this issue has been fixed and Windows 11 users can now simply click the “Make Default” button on a particular browser to set it as the default browser used by the operating system.
What’s New in Windows 11 KB5012592 Update
After installing today’s non-security update, Windows 11 build number will change to 22000.613.
Windows 11 Cumulative Update KB5012592 preview includes 26 improvements and fixes, with three highlights listed below:
- It is now possible to display up to 4 toast notifications simultaneously, three high priority notifications and one normal priority notification.
- We fixed an issue that could cause a Microsoft OneDrive file to lose focus. This means you will need to select or tap the file again to use it. After renaming the OneDrive file and pressing the Enter key, this problem occurs.
- We’ve updated the search so that when you search for the word “Widgets”, the corresponding Settings page is displayed.
Since Microsoft no longer provides full release notes in its cumulative update bulletins, you can check out the list of changes in the Windows Insider blog for the March preview.
