Having trouble opening the Windows Store? Many users see this error code: 0x80070520 every time they try to access Microsoft Store or try to open applications like Word Games, Xbox, etc. This is an error apparently observed after running the cumulative update, installing Windows 10 patches, or installing anything recently.
Damage to the Windows update components can cause this error, which in turn prevents the update process or the opening of applications and the Windows Store. The good news is that this error can be fixed and you can easily access the Windows Store again. Let's see how.
