if you are using Windows 8 or Windows 8.1 then you might be aware that Microsoft has improved a lot in UI of Windows Explorer. But in this new UI there is something which many users has complaint.
Back when Microsoft has released Windows Vista and then Windows 7, they had removed Up button from Windows explorer then many users had complaint about this and then Microsoft has put it back in Windows 8, as you know you cant please everyone so this move was not accepted by lots of users too.
Windows 8.x Explorer Rebar Tweaker is a freeware small portable app which allows you to remove Search Box and Up button from Windows 8 and 8.1 Windows explorer, not only this this tool also allows you to change the padding between address bar and search box in Windows Explorer and customize back and forward buttons width.
This tool allows :-
Hide the Up button
Hide the Search bar
Change padding after the search bar
Change padding before and after the address bar
Change the padding before the Nav buttons
To use this little app all you need to do is run exe file and then it will start running in background, now just run “ConfigurationGUI.exe” file to customize, once you make changes just restart the explorer and you are done.
