Microsoft starts rolling out new cumulative updates for Windows 10 which come with only a few fixes and performance improvements. In addition, the latest bunch of updates do not include any security fixes which is usually the case with those released on patch Tuesday.

It’s also worth noting that these cumulative updates aren’t meant for the latest Windows 10 Fall Creators Update (version 1709), as they’re designed for earlier versions of the OS.

For instance, cumulative update KB4049370 is for Windows 10 Creators Update version 1703, cumulative update KB4052231 is designed for Windows 10 Anniversary Update version 1607, while cumulative update KB4052232 is aimed at Windows 10 November Update version 1511.

Readers are also reminded that each of these updates bumps your Windows 10 version to 15063.675, 14393.1797, and 10586.1177, respectively.

Not to mention, the new batch of cumulative updates fix only a handful of bugs. For instance, cumulative update KB4049370 only fixes an issue caused by an earlier cumulative update KB4038788 for Windows 10.

Microsoft explains that it’s aware of the issue that led to a black screen on Surface Laptop after installing the aforementioned cumulative update as users had to hold the power button for a long time to restore normal functionality. However, cumulative update KB4049370 fixes that issue.

Elsewhere, cumulative updates KB4052231 and KB4052232 also include just a bug fix. Microsoft in its release notes explained that an issue has been fixed that where applications based on Microsoft JET Database engine ‘fail when creating or opening Excel files in .xls format.

However, Microsoft also notes there are known issues which each of the three new cumulative updates. The company says languages such as Arabic and Czech might automatically get translated into English for the Edge browser and other apps. The company says its aware of the above-mentioned issue and a fix for the same should likely arrive in the next cumulative update. For more information, visit Microsoft’s official support page.
