Under Win 7 command Ctrl+C ...
This newsgroup discusses Windows *XP*. The newsgroup for Windows 7 is
over at:
alt.windows7.general
... does not work in all programs. Other commands containing Ctrl
working properly. ...
Depends on the *unidentified* program. Maybe it has its own use for
Ctrl+C. Maybe it has configurable hotkeys and they've been defined to
include a redefinition of Ctrl+C. So far, only you know what is are the
programs where Ctrl+C does not work as expected.
It could also be you have other software that redefined this key
combination but only activates for those programs (e.g., Autohotkey or
AutoIt which trigger when they find you loaded those program). You
might have some key remapper running in the background.
... Replacing the keyboard does not remedy the situation. ...
Not a hardware issue. You didn't identify the SOFTWARE programs where
you expected Ctrl+C to work as the Copy [to clipboard] function.
Where should I look for faultiness?
First, check the unidentified programs. You didn't identify them so
only you know them. Read their help or ask its author about the masking
or overriding of the Ctrl+C keyboard combination.
Second, check what background programs you load on Windows startup and
login since those can affect behavior of programs. See if loading
Windows in its Safe Mode (which eliminates the vast majority of startup
programs) gets rid of the problem. If so, a program you load on Windows
startup or on login is causing the problem.
