Make sure you do a full Windows Update to get the latest updates and patches from Microsoft - should fix these sort of issues.
From the 'charms bar' go to settings, then click the link for 'PC Settings' In the app, goto the 'Update and Recovery' section, then click on 'Check Now' in the right hand side to check for updates - do a full install of all updates and firmware updates.
It's a good idea to leave Windows Update set to automatic updates - new firmware and patches come out monthly! Otherwise, make a note in your diary to check for updates manually every month!
