You will see how to change the taskbar size and position here. Let’s start with the latter.
By default, the taskbar in Windows 10 is at the bottom of the screen. However, you can move it to the top, left, or right. Let’s get started.
Unlock the taskbar. Drag and drop the taskbar to the desired position (top, left, or right).
That’s all. Lock the taskbar now if you desire.
Note: To restore the taskbar to its default position (bottom), drag and drop it to the bottom after you have unlocked it. You can lock the taskbar now if you wish.
Open the taskbar settings.
Open the drop-down list underneath the “Taskbar location on screen.” You can find this one between Show badges on taskbar buttons and Combine taskbar buttons.
Pick the location of your choice (Top, Left, or Right).
Note: You can set the taskbar to its default position by opening the above drop-down list and selecting “Bottom.”
Before proceeding, I recommend taking a backup of the Registry.
Go to the following: HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > StuckRects3.
Locate Settings in the right pane and double-click it.
In the second row, the sixth column, you’ll see 03 (which represents Bottom). To change your taskbar location, you must change 03 to one of the following:
00 – Left
01 – Top
02 – Right
Hit the OK button.

Once the taskbar is the size you prefer, stop dragging it.
That’s it. You can lock the taskbar if you wish.
