Windows 10 taskbar | how to make it thinner when vertical?

Solution 1:

You could use as tool called "Taskbar Tweaker". After a small search I've heard that it works well with Windows 7, 8 and 8.1. I don't know if it is already implement for Windows 10. According to some beta-tester it should work.

so try this:

1. Install 7+ Taskbar Tweaker.
2. Right-click on the Tweaker's tray icon, open advanced options and set no_width_limit to 1.
3. Then use the no_width_limit advanced option.

• Install 7+ Taskbar Tweaker and run it. You can close the dialog that is displayed.
• Make sure to dock the task-bar to the left edge
• Make sure that it is not locked
• Make sure that you have selected Use small icons option in the task-bar properties

Solution 2:

Right-click an empty area in the taskbar. Uncheck "Lock the taskbar". You should now be able to drag the edge of it to make it thinner (it works when I try it). Lock the taskbar again if you want to avoid accidentally changing it.
