iTunes won't run on Windows 10

I'm running iTunes on Windows 10. Windows and iTunes are both up to date. For the last couple of months I've had a lot of trouble getting iTunes to run on my computer. I've had to click the icon several times before it would finally come up. However, today I've clicked on the icon at least a dozen times over a period of 10 minutes or so and it still won't come up. So, I ran task manager to see if it's showing up but not showing itself. It doesn't come up in but it does come up in Background Processes - between 5 and 9 processes under iTunes, one of which is the actual program. But it still isn't displaying or printing. I've tried ending the process and restarting it, but it just keeps coming up in background processes, not in apps. This final problem started after I updated iTunes yesterday.
