How to change taskbar size on Windows 11

Windows 11 introduces an updated version of the taskbar with a new design that aligns all items to the center of the screen, and it includes new buttons for the Start menu, Search, Task View, and Widgets.

Although the taskbar has a similar design to the one available on Windows 10, the new version (currently) lacks some essential features, including the ability to change the taskbar size. However, it’s been discovered (via @thebookisclosed) that it’s possible to modify the Registry to change the size to small, medium, or large.
If you are among those users who like the classic Start menu, you can also bring it back on Windows 11 by editing the Registry with these instructions.
In this guide, you will learn the steps to make the taskbar larger or smaller on Windows 11.

Warning: It’s very important to note that modifying the Windows Registry can cause serious problems if not used properly. It’s assumed you know what you’re doing and that you have created a full backup of your system before proceeding.
