Ctrl+C key combination doesn't work

Question

On my Windows 8.1 laptop Ctrl+C does NOT work. I am able to copy using right click or using Ctrl+Ins. The other key combinations like Ctrl+V, Ctrl+X etc. all work.

Note that my C key also does work.

Answer 1

Is this issue for all applications, e.g. Notepad, WordPad, etc? If not, then the CtrlC combination might be in use in just one particular application.

Another possibility is that some other application is hijacking that key combination. To test that, restart in Safe mode, with startup applications disabled. Test CtrlC in Notepad. If it then works correctly, restart normally and use SysInternals Autoruns to find processes that hijack keystrokes. Use Task Manager to selectively kill suspect processes.

Finally, Nirsoft's ShortcutsMan lists Desktop and Start Menu shortcuts, and their HotKeyList shows registered shortcuts (though, regrettably, not the app registering them).
