Windows 10: taskbar lock inoperable

I have the lock the taskbar checked. However, without my doing anything, the taskbar will double or triple in height. I need to unlock the taskbar to reduce it's height, then I lock it again. This has been happening for a couple of weeks. The taskbar is at the bottom of my screen.

Any ideas how to fix this?

Windows 10 Taskbar sometimes on top of full-screen applications

Hi,

Thank you for posting your query on Microsoft Community.

I suggest you to change the Screen Resolution and check if this helps. Follow the steps below to do the same:

• Press ‘Windows ’ key on the keyboard.
• In the search box, type Settings
  
• SelectSystem > Display > Advanced display settings.
• Under Resolution, select a new value. We suggest you stick with the resolution marked
  "(Recommended)”.

Also try locking and then unlocking the Taskbar and check if this helps. Follow the steps below:

• Right-click an empty space on the taskbar.
• If Lock the Taskbar has a check mark next to it, the taskbar is locked.
  
• If it does not have a check mark, click Lock the Taskbar.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

toggle to switch taskbar location from bottom to right and back

Suggest you try simply dragging the taskbar with e.g. that command as a first step.

Then (and I don't know quite how you'd make use of it):
