The actual upgrade from Windows 7 to Windows 10 had only minor hiccups, but it did get there.
But now when I get to the Windows 10 desktop I see the Start Button, but it DOESN'T DO ANYTHING.
NO MENU appears when I click the Start Button.
I have rebooted the PC, but no change.
Additionally, when I right click the desktop and click on "Display Settings" or "Personalization" a warning pops up that says:
This app can't open
Your trial period for this app has expired. Visit the Windows Store to purchase the full app.
Isn't this a standard tool? What's happening here?
