Settings, Start Menu, Store and tray icons are not working (again)

And..... it happened again today, can you believe? I've never seen an OS as buggy as Windows 10, even after a clean install. This loss of settings protocol association issue is like a running gag and the "spiritual successor" to the issue in Windows 8.1 in which Modern apps, Store and Settings would not open, requiring a batch file with a script to restore their functionality. I've reported this issue several times in Windows Eight forums, and now it's Windows 10 time!

Sorry If I'm ironic, but I get mad because it's very frequent. I'm kinda afraid one of these days this fix won't work anymore, making a Windows 10 fresh install the only remaining way to solve this issue.

By the way, Microsoft has some insight and a possible fix for this issue:

Settings doesnt launch, or launches the Store instead - Microsoft Community

That specific issue was fixed months ago. It's likely there are a large number of possible causes of this problem, although they may all look the same, they probably aren't and each one will need to be analyzed and fixed individually.

I run this fix, and despite the wizard telling me that there wasn't anything to fix, I rebooted and Settings worked once more. Looks like just rebooting fixes this issue, so good so far.
