Lost my Start menu/Metro

[Mike Hayes Jr]

I am running Windows 10 build 10049. I have a Lenovo G500S. I have the built in HD 4000 graphics with a gen 3 core I5. I lost my start menu/metro. I can right click the icon I get the full menu. I can open Cortana and use it fine. I can open the notification and get to all of the functions. It's only the start menu/metro I can't open. Pressing the windows key does nothing.

I had the same problem. Turns out it was a corrupt file. Steps that worked for me HERE.

I'd send the feedback then do a clean install.

I just did a clean install and I have a bit more information. It didn't disappear this time until I started using Apps from the Metro part of the start menu.
