CCleaner broke my Win10 Start menu and modern apps

Running CCleaner Pro 5.09.5343 on Win10. I ran CCleaner and it made my Start menu and all modern apps COMPLETELY stop working.

The "My Account" link ( http://support.piriform.com/ ) is not working at all for me right now.

Is there a fix, of is this just one of those "Too bad!" scenarios?

Another sign that Win 10 is a rush job and that Win 10 doesn't pay too much attention to a thing called "Permissions".

But CCleaner didn't change permissions; it simply deleted certain items. Oh, I get it--CCleaner should not have been able to delete that stuff and ruin the shell and modern apps... Totally agreed. Very annoying issue. Probably going to have to restore an old Win8 image and re-upgrade... I mean re-update.

If you have a recent restore point you could see if it can undo the damage.

- This is not the first time a Win 10 user had these kind of problems.

- But the most recent version of Tweaking's Windows Repair (v3.50) is able to fix those problems. Run it before you re-install or re-upgrade Win 8 or Win 10. The latest version was just released earlier this week.
