High CPU usage because of wsappx, is there a solution?

Suddenly, my laptop fan started making noise, because of high CPU usage by the wsappx service and Task Manager indicated "Very high energy consumption". A quick search on the Internet discovered that I am not the first experiencing this problem. And the go-to "solution" seems to be to turn off Windows Store using the Group Policy Editor or the Registry Editor (I needed to do both). 

But this doesn't seem to be a very good solution, having to turn important Windows features off.

Will there be a fix for this issue?
