How do I get my windows (UK Layout) keyboard to work on Mac?

How do I get my windows keyboard to work on my Mac? I want to be able to bind the keys so it's like I'm using a windows computer, i.e. ctrl maps to command, but I've tried everything to no avail. Also, how would I map the symbols to the correct places, for instance \ is where ` should be, etc.

• To change the modifier keys, go to System Preferences → Keyboard → Keyboard and choose Modifier Keys….

  

• To map the keys to the correct places, go to System Preferences → Keyboard → Input Sources, click the + and choose British PC.

• To ensure that your keyboard is identified correctly, go to System Preferences → Keyboard → Change Keyboard Type and follow the instructions to allow OS X to identify the keyboard.

You can visualise how your windows keyboard is configured by showing the 'Keyboard Viewer'

System Preferences -> Keyboard -> Enable 'Show Keyboard, Emoji & Symbol Viewers in menu bar' -> go on menu bar -> click on the new icon -> Show Keyboard Viewer

And after that, you can reMap your keys with this really great soft :

By this way, you can easily revert your ReyMap to use the native Keyboard when you want.
