When I start my computer the task bar auto hides ok for 5 minutes and then it stops auto hiding until I restart again then it goes through the same cycle again I have checked the settings all ok. Anybody have any ideas how to solve it?.
This may not be a permanent solution but it might return your taskbar to normal operation without having to reboot the computer.
If the taskbar won't stay hidden after setting properties to do so, try killing & restarting explorer.exe as follows:
Open a command/run window (WIN + r)
In the Open: box type "CMD" (without quotes)
A command line window will open with a prompt like this:
C:\Users\
username>
Type the following commands (without quotes) & click the Enter key after each one.
"taskkill /f /im explorer.exe"
"start explorer.exe"
Then exit the command window by typing EXIT at the prompt.
