Start Menu and All Taskbar apps are GONE!!!

Ryker XL

So been working on this all morning.

My Start Menu is toast. Causes critical re login error. Re login does nothing...

Bing and store apps are gone from taskbar

Speaker volume does NOT work

Notifications are unresponsive

Cortana causes critical error as well

Ran Powershell fix as admin....sea of red. Restart did nothing...

Ran scannow... all is fin, but obviosuly not

Ran reboot in safe mode... nope

Will see if I can find system restore...

But unless someone has a quick fix, is there any way to go back to 7. I have the disc....this is rediculous!!!
