SOLVED: When I RIGHT CLICK the START BUTTON Nothing Happens in Windows 8.1

If you right click on the START button but do not see a context menu you likely have corrupted or missing folder:

c:\User\<user>\AppData\Local\Microsoft\Windows\WinX

The solution is just to copy this folder (and its three subfolders) from a working machine.  In my case, I was able to copy these files from a different Windows profile that was not experiencing the problem.

Also, in case you have not figured this out yet, you can customize your right click menu by making changes to:

c:\User\<user>\AppData\Local\Microsoft\Windows\WinX\Group1

c:\User\<user>\AppData\Local\Microsoft\Windows\WinX\Group2

c:\User\<user>\AppData\Local\Microsoft\Windows\WinX\Group3
