As you’re probably aware, Windows 10’s latest monthly security updates have an issue with the taskbar. This problem was first reported after Microsoft enabled News and Interests feed for everyone, and it affects users running May 2021 Update, October 2020 Update and May 2020 Update, and the retired November 2019 Update (version 1909).

KB5004237 update

According to reports and Microsoft’s documentation, the news and interests button in the Windows taskbar might have blurry text. In addition to blurry text, icons may not render properly for other apps, such as To-Do, Chrome, Edge, etc.

Although there’s no mention of a fix for broken taskbar icons bugs in the release notes, in our tests we observed that Microsoft has finally patched this bug. For those unaware, that taskbar bug also corrupted the system tray icons, including notification center and calendar flyout.

Affected users reported that the taskbar icons can vanish entirely due to the buggy updates, impacting the performance of some apps and Windows 10 features, such as sound and notification flyout.

As of July 12, Microsoft hasn’t officially acknowledged the taskbar problems, but if you have these issues, installing today’s cumulative update should help.

If you continue to have taskbar issues, you can change the location of the taskbar and move it to the top of the screen. Or you can also play with the Settings > System > Display > scaling settings. For example, make sure that you use the ‘recommended’ option for your scaling settings.

You can also try re-enabling News and Interests feed.

Performance issues

With today’s security update, Microsoft has finally fixed a bug that caused frame rate problems for PC gamers. The problems came from security updates released in March, with several users reporting that they were seeing stuttering and frame rates lower than expected.

Some users fixed this by installing the recent cumulative updates and others rolled back to older versions.

Windows 10 Build 19043.1110 cumulative update finally addresses a multitude of gaming issues affecting recent versions of Windows. Microsoft has also fixed issues that could result in a Blue Screen of Death (BSOD) for some users.

According to the official release notes, Microsoft is not aware of any new issues, but we’ll update this article if we come across a new critical bug.
