Windows 10, fully up to date - Version 1511 (OS Build 10586.0)

Cannot open Start Menu, Cortana, Volume Controls, Notifications - anything on the task bar.

This issue was caused by:

1) explorer.exe being terminated one time, yesterday

I have tried every fix available through standard searches. Everything included here has been tried.

I can see any time I click anything on the task bar, a WerFault.exe runs, which is "Windows Error Reporting", but this is only through watching Taskmanager, as nothing actually comes up when I click anything.

I can't even right-click non-Windows applications on the task bar, such as right-clicking a Chrome window to close it or whatever else.

If attempting to open Start Menu, Event Viewer generates 5 events:

1) Faulting application name: ShellExperienceHost.exe, version: 10.0.10586.0, time stamp: 0x5632d93d

2)

Fault bucket 133232457255, type 5
Event Name: MoAppCrash
Response: Not available
Cab Id: 0

3)

Faulting application name: SearchUI.exe, version: 10.0.10586.0, time stamp: 0x5632d66d

4)

The dump shows an Access Denied error:

Run Process Monitor in background, while trying to open the startmenu or any other operation which causes the crash, and look in the Result column which operation fails with Access Denied error.

Also try to run this update which repairs the ACL which also can cause the errors.

One of our Windows 10 PCs exhibited this behaviour after the anniversary update was installed. Clicking on the start menu wouldn't work. When I looked in the Event Log it said:

Faulting application name: ShellExperienceHost.exe, version: 10.0.14393.187, time stamp: 0x57cf9d73
Faulting module name: nvumdshimx.dll, version: 21.21.13.6909, time stamp: 0x579f36b5
Exception code: 0xc0000005
Fault offset: 0x0000000000051979
Faulting process id: 0x1594
Faulting application start time: 0x01d2290588da8cb1

The faulting module nvumdshimx.dll turned out to be part of an Nvidia driver installation. Once I removed the Nvidia drivers the start menu worked again.
