Microsoft recently released cumulative update for Windows 10 Version 1903 and 1809 for x64-based Systems (KB4503293) and (KB4503327). But it seems like the update breaks the Custom Views in Event Viewer in Windows 10.

After installing the latest update, lots of users start reporting about the same error. What actually happening is:
After installing the (KB4503293) and (KB4503327) Update, it breaks Event Viewer ‘Custom Views,’ meaning they can’t be viewed and Event Viewer crashes. When trying to access them, a quick dialog box opens up showing an error message which reads:
“MMC has detected an error in a snap-in and will unload it”

After that, if you select “Unload the snap-in and continue running,” and click OK.
Now another dialog box “Unhandled Exception in Managed code Snap-in” opens showing the following messages:
![Fix - Windows 10 1903 Cumulative Update (KB4503293) & (KB4503327) Breaks Event Viewer Custom Views 3 Unhandled Exception in Managed code Snap-in](https://geekermag.com/wp-content/uploads/2019/06/unhandled-exception-in-managed-Code-Snap-in.png)
The process cannot access the file ‘C:\ProgramData\Microsoft\Event Viewer\Views\View_0.xml’ because it is being used by another process.”
