SharpKeys is a small Windows utility that lets you change what any key on your keyboard does. For example, you could make the Caps Lock key work like a Shift key, swap the positions of two keys, or disable a key entirely. It does this by editing a specific Windows Registry value that controls key remapping, which has been part of Windows since Windows 2000. SharpKeys provides a simple point-and-click interface so you do not have to touch the registry editor directly. The application includes a list of common keyboard keys to choose from. It also has a Type Key feature: you click it, press the key you want on your physical keyboard, and SharpKeys identifies it automatically. The one exception is the Alt key, which Windows intercepts before SharpKeys can see it, so you have to find it manually in the list. Once you pick a source key and a destination key, you click Write to Registry, then log out or reboot for the change to take effect. A few important limitations apply. SharpKeys can only remap whole keys, not key combinations like Ctrl+C. It cannot remap mouse buttons. Keys that are handled entirely by the hardware before reaching Windows, such as most Fn keys and some media keys, cannot be remapped this way. The remapping applies at the machine level and affects all user accounts on that computer. SharpKeys is available from GitHub releases, the Microsoft Store, winget, and Scoop. The installer covers x64 and x86 Windows, ARM users should download the ZIP file instead.
