Hard reset your phone. This is not normal as the 520 is very stable.

Microsoft apps are in the store, simply install those you want again.

You could also try the Nokia software recovery tool.

I didn't know the 520 can get Denim. Checked mine for updates and there is none. Should I not install when it comes?

Try clearing temp storage or uninstall last app.

Nokia recovery software shouldn't require up button to re-flash the phone. Battery Sense cannot be uninstalled as it is part of the OS. It always lists in the app list (scroll right) and can be Pinned to the start by a long press/pin.

If you're missing these you don't have Windows Phone 8.1 and only have Windows Phone 8 installed. Reflash with latest firmware to 8.1 using tool mentioned.
