I Hate This Key can customize any system-wide keys on any keyboard. This means deactivating a key completely (a very popular option for Caps Lock), customizing them (for example, activating Caps Lock only when pressed twice or held down), F-Lock inversion option for the functional keys (F1 through F12), forbidding deactivating of Num Lock or any other key, and allowing game users to block infamous Windows Logo key along with system-wide key combinations (like Win+D) while playing games.
