问题

超级用户Google Services想知道，在朋友愚人节恶作剧彻底搞砸了他的键盘后，如何重置他的键盘映射：

My friend/enemy switched the mapping for the keys on my keyboard as an April Fool’s Day joke. When I press Y, Z appears on the screen. Some keys still function properly such as B, X, G, I, D, and a few others. Also, when I press Ctrl, it functi*** as the Enter key. Even the function keys have been switched around!!

I called a technician, but even he was unable to find the problem and told me that reinstalling the operating system was the only way to go. I really do not want to resort to calling my friend and asking him how to undo it.

I am using Windows 7 Professional 64-bit and thankfully, at least, there is no problem with my mouse. Can you help me?

答案

超级用户贡献者RJFalconer和Ben N为我们提供了答案。首先，RJFalconer：

In this case, it sounds like a different keyboard layout has been set as the default (i.e. German, since that would cause a swap between Y and Z).

You can change your keyboard’s layout via the Control Panel:

Clock, Language, and Region
Region and Language
Keyboards and Languages Tab -> Change Keyboards

Press Alt+Shift to switch keyboard layouts.

However, this does not explain the problem with the function keys. It is possible to arbitrarily remap keys via the registry. I think you will need a third-party tool to fix this (SharpKeys, for example).

Remember, you can also use the On Screen Keyboard to type with your mouse (Start Menu\Programs\Accessories\Ease of Access\On Screen Keyboard).

然后是Ben N的回答：

If you do not want to use third-party applicati*** to reverse the SharpKeys modificati***, you can cut out the middleman and edit the Registry directly.

Open the Registry Editor by navigating to C:\Windows\regedit.exe in Windows Explorer. Once it is open, navigate here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

If there are entries named Scancode Map or Value Scancode Map, delete them. Those entries are what causes Windows to remap incoming key presses from the keyboard.

Once you are done deleting them, restart your computer. Key mappings will be reset to their default settings. You can accomplish all of this with your mouse only and no keyboard.
