Start doesnt open

Hello i have moderately annoying thing, my start menu wont open after start.

It have different icon that it should, i dont see any pinned programs except cortana.

I can right click on menu with this options:

When i press exit, my start menu is back


I can live with that, its not that big deal. Tho i tried many solutions i found on web that should have solved it, but they did nothing.

Just wondering if anyone encountered that and know solution

Thank you ztruker. Tried to run this with this output:



I guess i should find a way to "reinstall" cortana and that shell so i can apply fix?

Thank you for your time and help Brink and Ztuker. I eventually found (while closing that bugged start) there was Gigabite something on it. Since i uninstalled Gigabite smartswitch (some utility for MB), i have no problem again.
