Windows directors who open the native Even Viewer after set up of KB4503293 or KB4503327 might obtain an error message after they choose Custom Views within the Event Viewer.
Microsoft launched cumulative updates for all supported variations of Windows 10 (and different Microsoft working techniques) on yesterday’s Patch Day.
KB4503293 for Windows 10 model 1903 and KB4503327 for Windows 10 model 1809 had been amongst these patches. The cumulative updates closed a number of safety vulnerabilities — a few of which rated with a crucial severity — and launched different modifications on gadgets operating these variations of Windows.
Updates might introduce errors and points, and that seems to be the case with KB4503293 and KB4503327.
Windows customers who open the Event Viewer, e.g. through the use of the Windows-X menu or looking for Event Viewer within the Start Menu, might obtain the error “MMC has detected an error in a snap-in and will unload it” on begin when customized views are chosen.
The solely choices supplied by the dialog are to “report this error to Microsoft, and then shut down MMC”, or to “Unload the snap-in and proceed operating”.
Selecting the latter throws an “unhandled exception in Managed Code Snap-In” which causes fairly the chaos within the Event Viewer.
The solely choice left at that time is to restart the Event Viewer. Problem is: the error is thrown once more as soon as you choose customized views within the software.
Our colleagues over at Deskmodder discovered an answer that fixes the difficulty. Here is what it’s good to do:
- Open File Explorer on the gadget.
- Navigate to the next path: C:ProgramDataMicrosoftEvent ViewerViews
- Backup the content material of the folder.
- Delete all View_X.xml recordsdata within the folder (it begins with View_0.xml and increments the quantity by 1 for every file).
- Start the Event Viewer after deleting the recordsdata.
The error needs to be gone after the deletion. A restart isn’t required to repair the difficulty.
