problem:
If you suddenly find that you use shortcut keys properly before catastrophic failure, you must first suspect is not a hotkey conflict, then you will see open applications for conflicts, and then view the hotkey QQ, micro-channel hot key, hot key input method, etc. and so on, or you wonder whether what key to press to use the wrong lock key win, such as win + fn and so on, and some even wonder if the computer you will emerge with a virus, system modifications are required we usually think of first, then probably go back and check verification, but often you will find that none of these questions, your hotkey respective applications What ever happened to win a hotkey conflict, 360 repair system reboot did not improve, or to see some people say changes registry, but you find that the value is actually no need to change and so did not succeed after the test method, then you can consider the following in this way.
Solution:
1, you may not shut down the computer for a long time, causing your keyboard corresponding driver files are temporarily disabled. At this point only need to unplug the keyboard inserted under the rewriting can be resolved (mostly)
2, you can try to repair the system by to see if you can solve (small portion)
3, modify the registry (small probability)
