Serious issues with Windows 11 are affecting millions of computers. Another patch has failed!

Windows 11 is experiencing another mishap, and the latest update only confirms that some bugs have been trailing the system for months. Issues that arose earlier in version 24H2 have also carried over to 25H2 — and not by chance. Both editions use the same code base and the same servicing branch, which Microsoft officially confirms.

However, the most important aspect is how these bugs manifest in practice. They strike at the foundations of the user interface. XAML-based applications — namely the Start menu, File Explorer, search, taskbar, and system settings — can function unstably, freeze, or launch with noticeable delays.

Problems Persist from Update to Update

The October patch (KB5066835), designed for Windows 11 25H2, did not resolve these issues. Worse yet, the next one — KB5070311 — also did not bring any improvement. This means that Microsoft is battling errors at the system architecture level rather than a single component.

Who is Affected?

According to Microsoft, primarily corporate and managed environments. This is where UI problems most frequently appear and in the most severe form. Home users — at least according to the official narrative — are said to experience them rarely, although the giant from Redmond does not rule out that issues may also occur on regular computers.

A temporary workaround is to restart the SIHost.exe process, which is the shell infrastructure host responsible for interface elements.

A system that a billion devices still refuse to use

Errors have always occurred — it's a natural part of software development. The problem is that they concern the very foundations of the operating system's functionality, making them particularly troublesome. And if we add to this the fact that Windows 11 still struggles to win over users — while a billion computers continue to run on Windows 10 — it is clear that Microsoft needs to deliver more than just cosmetic fixes.

For now, however, it seems that the next patches are more about putting out fires than genuinely improving system stability.
