Update KB5001330 for Windows 10 may cause annoying issues

On Tuesday, Microsoft released the April cumulative update for Windows 10, which should mainly improve the security of the operating system. And also fix some issues from previous updates, such as the blue screen of death when using some printers. But since Tuesday, the Feedback Hub application, discussion forums, and social networks have been flooded with comments from unrelated users, to whom the last update did more harm than good to their computers. Problems don't affect all users - in most cases, everything probably works according to plan. Nevertheless, users should be on the lookout and, in case of a concern, prefer to wait until next week, when perhaps the developers will catch all the flies.


The issues are specifically related to cumulative update KB5001330, which is designed for Windows 10 in versions 2004 or 20H2 and changes the build number to 19041.928 and 19042.928, respectively. If you are using Windows 10 version 1909 or earlier, then you are affected by other cumulative updates that may not suffer from these errors at all. The first complication that users encounter may occur during the installation itself. The most common error is 0x800f081f, or 0x800f0984 or 0x800f0922. One of the owners of two different Surface devices noted that this is the second month in a row that he has failed to install a cumulative update on his computers.

The update also caused wrinkles on the foreheads of some players. In some cases, there may be a significant drop in frame rate (FPS), but also other problems such as image tearing, jams, or game crashes. To a lesser extent, users report screen flickering when using Chrome and Edge web browsers, bootloopy with error code 0xc000021a, or a blue screen of death. It seems that the problem with temporary profiles, which we have not heard about since last December, could also occasionally return. After the update, a new user profile is created on the computer, which can lead to, for example, the loss of access to some files.

If you are affected by any of these errors, you still have the option to uninstall the faulty update. Just open Windows Update, where you go down to View update history. Then select the Uninstall updates option and then select the appropriate update from the list. After the computer restarts, you return to the previous build of Windows 10. If you have not yet upgraded to the update, you can also pause the update in Windows Update for 7 days or another period of time.

According to Microsoft, the cumulative update to Explorer.exe KB5001330 should fix a number of issues with the strange behavior of Windows.exe, improve the security of many components in operating systems, or remove an older version of the Edge browser (so-called Legacy without the Chromium kernel).
