Itunes doesn't open on windows 8

I downloaded itunes onto my windows 8 computer around 2 months ago. I didn't seem to have any issues to start with, but sometimes it doesn't launch.

If i restart my computer, it normally works, but i was just wondering if there is a way of fixing it?

I tried changing the compatibility, and troubleshooting, but neither seem to work.. I have also scanned my computer for viruses. No viruses there..

help 😟
