Control Panel/Programs & Features/Power Options/System do not open

I installed an application "Clone File Checker" and uninstalled that using "iObit Uninstaller" with Power Unistall" option. After that, i am not able to open Control Panel, Programs & Features, Power Options and System from the Start Menu. Clicking on each of these gives an error in the enclosed screenshots, but all of them display the error message "This file does not have an program associated with it to perform this action. Please install a program, or if one is already installed, create an association in the Defaults Program Control Panel". Only the file names are different. When I try to set the Default Applications, I do get a similar error message.

Moreover, clicking on the File Explorer from the Start Menu opens the Explorer screen, but when I pin to the Taskbar and subsequently attempt to open tit from Task Bar, I get an error message.

Appreciate any help. Thanks.

I have on occasion used iObit Uninstaller but only in the most severe situations. iObit Uninstaller does seem to have a reputation of doing more than what one expects. You might try System Restore to a day before the program was installed. If that doesn't work there's other options in Recovery but they can be more severe that what is needed so be sure to read everything carefully.

can you right click on start get to a admin command prompt and run ,,, sfc /scannow

When I attach an external hdd to my USB port i get the same message (see attached). What do I do?

Yes it's formatted.
What does " Do you have any ? in device manager??" mean?
