I have absolutely no idea how I managed to break these two combinations.
StickyKeys isn't enabled.
Any other key combination works.
I accidently hit the sleep mode button (on keyboard) I assume that broke shift + c, but ctrl + c wasn't working before.
I'm desperate; searching the web for solutions didn't bring up one yet.
it's a desktop pc,
they're broken since yesterday I may noticed ctrl + c earlier as i use shift + c less often
ctrl in any other combination works so does the right shift (left one even with C)
reinstalled keyboard drivers, sfc /scannow and unchecking in systemconfig/services+boot unnecessary services didn't anything good
Is it a keyboard that requires software to be installed to control media functions etc?
Does it have macros?
If so, perhaps uninstall that driver/software and try using the Windows default HID-Keyboard driver to see if that makes a difference. if it does, there's provbably a setting in the app software causing the issue.
actually I reinstalled the HID-Keyboard driver, since i'm running Windows 7 for almost a year (before vista) didn't use the provided driver
some macros are working like sleepmode, calc, play/pause etc.
