I am having similar issues to what others had. I upgraded from Windows 8.1 to Windows 10, and all went fine and smooth except for not being able to right-click some shortcuts in start menu or taskbar.
For instance, right-clicking the Word 2013 icon does nothing (Thanks to my firewall I noticed that it launches the Windows Problem Reporting thing in the background). Clicking to expand the jump list also does the same. Right clicking Word's icon in the task bar also does this.
This occurs with various applications (e.g. Word, Excel, Powerpoint, Mathematica, etc).
I have already tried:

- I've also included disabling all non-Windows context-menu options and restarting explorer.exe, but to no avail
