Windows 10 KB5013942 crashes Event Viewer and causes other issues

Written by admin

Some users are experiencing serious issues after the release of Windows 10 May 2022 Update. Although Windows 11 users have experienced app crashes after installing KB5013943, it seems that this month’s new major update KB5013942 is causing problems for Windows 10.

Earlier this week, Microsoft released Cumulative Updates for Windows May 2022 for Windows 11 and Windows 10. Like the previous releases, a Cumulative Update is a mandatory download that aims to fix the issues and security vulnerabilities caused by the previous update.

This month’s update for Windows 10 fixed a number of issues, including a bug that slowed the system’s boot time to 40 minutes (not seconds). There are now some reports coming in that the May 2022 Update itself won’t install on Windows 10. The installation issue isn’t a big deal, but it seems that the patch broke apps for some people as well.

After installing KB5013942, users cannot launch Event Viewer. For those who don’t know, Windows Event Viewer is a tool for administrators to check app logs and system messages, including errors, warnings, and warnings.

‚ÄúThere were some issues installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80073701),” one affected user described their experience installing the update.

“Aside from Event Viewer no longer opening, it appears that this patch removes (or disables) files related to .NET 5. For me, my Fijitsu scanner software ScanSnap is now missing mscoree.dll errors,” another user marked Event Viewer issues and app crashes on Windows 10.

Comments on Windows 10 May 2022 update issues are also available on the Feedback Hub, with one user commenting, “Apparently this update is causing some driver incompatibility on my system as I’m constantly getting exceptions to the machine check after installation. Immediate after boot when all background services start. Everything worked fine before this update”.

There are several posts in our own comments section and on social media sites that Event Viewer and app crashes are a growing problem.
