Choose the icon you wish to use to use for the specific folder and then click on the Emblems tab at the right. Press the Win + R keys to open Run, copy and paste %UserProfile%\Downloads\desktop.ini into Run, and click/tap on OK to open that file. It is a great way to clean up Windows and add a personal touch to folders. It is important to note that while you are able to modify icons in a specific way but you cannot alter the whole dock… Look for unsafe settings and passwords, insecure extensions, and outdated software.
