I have done several in-place upgrades from Windows 7/Win 8.1 to Windows 10 without any real issue. But yesterday I unboxed a new Lenovo computer that came pre-installed with Windows 7 Pro, and I used the same Windows 10 USB stick that I have been using to upgrade this computer.
All seemed to go fine with the upgrade, and I was able to login successfully, including using IE and Edge to access the Internet. 
But, when I tried to click on Settings, I would see a quick flash on the screen, but nothing else.
I tried rebooting several times with no improvement. –>
I checked the event log and found a pair of events (Id 59 and 5973) that indicates an issue with Immersive Control Panel.
Doing a web search indicated that this issue has been encountered since the initial release of Windows 10 back in July 2015, but also, similar errors with Windows 8.1.
I finally found a Microsoft Answer post (click here) that pointed me in the right direction for a solution. Microsoft pushed out an emergency troubleshooter utility that you can download directly from the Microsoft web site:
Download, open and run this troubleshooting utility. It should identify the issue and fix it. No rebooting is required. It fixed my issue with opening the Settings app immediately.
Hope this helps!
