I had a BSOD, so I forcibly shut down my PC. When I restarted it, it took some time to install a few Windows update; then the %temp% path was changed and I had to change it back.
Before I restarted my PC, Cortana searching from the Start menu wasn't working, and it didn't work after I set back my temp directory.
When I try to run Cortana it doesn't launch at all; nothing happens. It doesn't appear in the Task Manager window, and the search bar in the Start menu isn't activated.
Searching itself is working. I can search in any place rather than the start menu.
I've tried to restore Cortana using magicandre1981 answer but I didn't work either.
How can I make Cortana work again?
