If you've ever experienced issues with the Start menu in Windows 10 (won't open, tiles disappearing, etc.), Microsoft has a cure for what ails you. The newly released Start menu troubleshooter will automagically check for and repair any issues it finds.
To download it, click here for the direct link or here for the indirect link if you're the cautious type. And if you're having trouble with the Store or your printer, official troubleshooters exist for that too and can be found with a simple search on the Microsoft support website.
