Windows 11 does not provide built-in options to customize the taskbar clock's font, size, or color. To achieve this, users need a third-party tool called Windhawk along with its Taskbar Clock Customization mod. Testing on Windows 11 Pro version 25H2 confirmed that the mod allows changes to the clock's font family, size, weight, and color. The mod requires Windows 10 64-bit or Windows 11 (version 22H2 or newer) and must be installed from windhawk.net. Users need internet access for the initial mod load, as Windhawk downloads necessary debug symbols. Windhawk is open-source, and while generally safe, code injection may trigger antivirus alerts. Users can revert to the default clock by disabling or removing the mod through Windhawk.
