The Taskbar with the Start button on it can be hidden off-screen. To restore the Taskbar, use one of the following methods:
- Move your mouse cursor to the edge of the screen where the Taskbar was last located.
A thin gray line should appear along the edge of the screen where the Taskbar was last seen.
- When the cursor turns into a thin arrow pointing away from that edge, click and hold the left mouse button and drag away from that edge.
This should allow users to drag the Taskbar to the wanted size.
Booting into Safe mode and back into normal Windows should help users get the Taskbar back:
See Dell Knowledge Base article How to Boot to Safe Mode in Windows 10 and Windows 11 for more information.
