Microsoft rolled outWindows 10Build 14366a couple of days ago, and as always, users flooded Microsoft’s Forum after they installed and tested it. ManyInsidersreported that Windows displayed an unusual“class not registered” errormessage when trying to access Settings, Edge, Groove and OneDrive.

And this is not all, asInsiderscan’t open the Action Center, and the Search and Desktop apps are unresponsive, they don’t do anything when selected.

Have installed build 14366. When it was finished, it generates a “Class not Registered” error when attempting to access the following apps: Edge, Settings, OneDrive, Groove. […] Cannot open the Action Center, Search, or desktop (it does nothing when selecting them).

Luckily, it would appear that I can still access email (outlook 365) and IE11.

As I cannot access the settings folder, I can’t back out. As, I essentially am stuck in the mud, can anyone please help???

Insidersrestarted the system, and tried other troubleshooting methods – all to no avail. It appears that this issue is usually caused by a third party security program that has detected a new Windows file as a false positive. As a results, it prevented it from getting properly set up in the registry.

This usually happens whenInsidersdon’t cleanly uninstall any third party security program before upgrading to a new build. If you’re in this situation, you need to do aclean ISO install, and then uninstall the Webroot.
