Changing the size of the taskbar in Windows 11 is a quick and simple process. While Windows 11 doesn’t offer taskbar size adjustments through its settings menu, you can change it by tweaking the Windows Registry. This method involves modifying a specific registry key to alter the taskbar’s appearance. Here’s how you can do it step-by-step.
How to Change Taskbar Size in Windows 11
To change the taskbar size, you’ll need to modify the Windows Registry. This process will enable you to make the taskbar small, medium, or large, depending on your preference.
Step 1: Open the Windows Registry Editor
Press Win + R, type regedit, and hit Enter.
This will launch the Registry Editor, a powerful tool that allows you to make changes to system settings. Be cautious while using it because incorrect changes can affect your system.
Step 2: Navigate to the Taskbar Settings
Go to HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced.
This path leads you to the location where taskbar size parameters are stored. You’ll find several settings here that control taskbar behavior.
Step 3: Create a New DWORD Value
Right-click on the Advanced folder, choose New, then select DWORD (32-bit) Value.
This action prepares a new entry for customization, which will specifically control the taskbar size.
Step 4: Name the DWORD Value
Name the new DWORD value TaskbarSi.
Naming it correctly is crucial. This value directly affects taskbar size, and a typo here could lead to unexpected results.
Step 5: Set the Desired Size
Double-click on TaskbarSi, set the value to 0 for a small taskbar, 1 for medium, or 2 for large, and click OK.
These values correspond to different sizes: 0 for small, 1 for the default medium, and 2 for large. Choose what suits your preference best.
After completing these steps, restart your computer for the changes to take effect. You’ll notice the taskbar size has adjusted according to your setting, providing a new look and feel to your desktop environment.
