Windows 10 Start Menu "Best Match" won't open

If you open your Win 10 start menu, search for an app and then click or press enter on the "Best Match" result, and it won't open, it's ANNOYING.

The solution is also annoying. There's a folder in your AppSettings that you're going to need to delete:

C:\Users\YOUR_USERNAME\AppData\Local\Packages\Microsoft.Windows.Cortana_cw5n1h2txyewy

However, you can't delete it while you're logged in. So you're going to need to:

1. Create a new user, or use an existing other account that isn't currently logged in.
2. Make it Admin or give it write permissions on your user folder mentioned above.
3. Log out of your problem account.
4. Log into the new account.
5. Find the folder mentioned above and delete it.
6. Log out of the new account.
7. Log back into your old account and the problem should be fixed.
8. Don't forget to remove Admin role from the other user and remove any permissions you gave it.
