Class not Registered error for pictures with Windows 10

My solution to a similar problem on a new Windows 10 PC...

PROBLEM: Class not Registered error when trying to open a .jpg file.

STEPS TRIED: 1. START-->SETTINGS-->SYSTEM-->Default Apps-->"Reset to Microsoft recommended". 2. SFC scan didn't find any problems. 3. Clean boot didn't help. 4. System Restore to a time when I know things were working didn't help.

The problem remained. Right clicking on the file and selecting OPEN WITH listed PAINT and TWINUI. Paint could open the file, but TWINUI always gave the error. The extended OPEN WITH menu did not list PHOTOS anywhere.

SOLUTION: I pressed START-->ALL APPS-->PHOTOS. Once the program opened once, some setting somewhere got fixed and double clicking on a jpg file worked again. The OPEN WITH menu changed to have PAINT and PHOTOS as the first two options. TWINUI does not appear
in the list anymore.
