Windows 10 gets one of its final non-security updates under KB5063842

Microsoft is rolling out KB5063842 for Windows 10 users. This non-security update delivers several fixes for the outgoing operating system.

It is the last Tuesday of the month, which means it is time for non-security updates for Windows 11 and 10. If you are still on Windows 10, you can download KB5063842, one of the final non-security updates before Microsoft pulls the plug on the operating system in October 2025.

Here is what is new in KB5063842 with build number 19045.6282:

[Common Controls] Fixed: An issue that affects how certain supplementary characters appear in Windows textboxes.
