Problems with the Start Menu not opening

Hi!

I've looked through and ran various troubleshooters I was able to find regarding the Start Menu which refuses to open since I upgraded from Windows 8.1 to Windows 10. Needless to say, none of them worked, so here I am.

The problem, however, runs deeper than just the Start Menu. Basically, everything on the taskbar that's not a pinned program, doesn't work. I can right-click the task bar just fine and the menu opens and I have the options to open the Control Panel, Task Manager, Power Shell etc. However, right-clicking any of the pinned programs does nothing. On my other systems, if I do that I get some options (e.g. if I right-click Visual Studio, I get a menu which enables me to open one of the recent solutions). I know there is an option that I need to set up to enable this feature, and I have it enabled, but the context menu that should display this simply doesn't open. Consequently, I can't pin any new programs to the taskbar, or un-pin old ones.

Furthermore, one of the tutorials suggested I try enabling and then disabling a full screen start menu through settings. However, I noticed that no matter what I do, the system won't remember that I toggled the full screen start menu button. I set it to ON, exit settings, re-enter settings, and it shows as being OFF again.

Next, clicking the date and time on the taskbar should open up a monthly calendar. Well, not for me. The calendar is completely unresponsive. Right-clicking the notification in the tray shows the option to open the action center, but the action center doesn't open.

Any ideas on what I can do? Are there any logs that might shed light on what's gone wrong?

Looks like I'm not the only one having start menu issues:

Start menu, search, and right clicking taskbar doesn't work - Windows 10 Forums (less severe, because restart fixes it)

Someone give us a hand? :)

You could try downloading shexview and disabling all non-ms context menu entries as this is often a cause of right click weirdness.

For your start menu problem though I'd create a new user account and see if things works there. If that doesn't work then a repair install is easy and only takes half an hour or so (you get to keep all your non store programs and data etc).

lx07 nothing worked. Same thing as before.

I fixed it.

The problem was that Administrators did not have access to

C:\Users\MY_USERNAME\AppData\Local\Packages

Would have been SOOOO much easier if there was a friggin' LOG somewhere!!!

So much for generic "fixes". Total bollocks.
