My friend/enemy switched the keys on my keyboard as an April fool's joke. When I press Y, Z appears on the screen. Some keys work like b, x, g, i, d, and a few more. Also, when I press ctrl, it returns Enter. Even the function keys are switched!!
I called a technician and even he wasn't able to detect the issue and told me installing the operating system was the only go. I really don't want to call up my friend and ask him.
I'm on Windows 7 Professional 64-bit and there is no problem with my mouse. (Thank God)
Can you help me?
