Issue: How to fix "A toolbar is already hidden on this side of your screen" error in Windows?

Hello. The taskbar auto-hide function keeps resetting every time I restart my Windows 11 computer. What should I do?

Solved Answer

The taskbar in Windows 11 can be used for seeing your apps and checking the time. People can personalize it in many ways – change the color, pin their favorite apps to it, and move or rearrange taskbar buttons. They can also check the computer's battery status and minimize opened programs so that they can take a look at the desktop.

However, in some cases, users want to hide the taskbar, for example, if they have multiple monitors. Windows has an auto-hide feature that should help but some people report that it malfunctions. The taskbar keeps reappearing even if the auto-hide function is enabled.

Sometimes users also see an error message – “A toolbar is already hidden on this side of your screen. You can have only one auto-hide toolbar per side.” Due to this, the taskbar auto-hide setting resets to unhidden when people restart their PCs, and this can get very annoying. It is unknown what exactly causes this issue but in this guide, you will find 7 possible solutions.

Keep in mind that the manual troubleshooting process can be lengthy, so you can use a maintenance tool like ReimageMac Washing Machine X9. It can fix most system errors, BSODs,[1] corrupted files, and registry[2] issues. It can also clear cookies and cache[3] which should improve performance. Otherwise, follow the step-by-step instructions below carefully.

Even if you apply the most secure settings via your web browser, you can still be tracked via apps that are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
