Windows 7 users can, drag the desktop icon or other Program icon to the taskbar, And then you can see the large icon in the taskbar. However, after you start the system, you cannot add a shortcut icon by dragging or dragging it. Even if you find the original file and click lock to the taskbar, you cannot see the taskbar display icon. In this case, I want to resolve the problem that the shortcut icon cannot be added to the Windows 7 taskbar, helping you find a solution and solve the inconvenience caused by small issues. You cannot add shortcuts to the Windows 7 taskbar: 1. if the shortcut icon cannot be added to the Windows 7 taskbar, expand "start"> "run" (or use win + r)> enter the following content in sequence and confirm: CMD/K Reg Add "hkey_classes_root \ lnkfile"/V isshortcut/FCMD/K Reg Add "hkey_classes_root \ piffile"/V isshortcut/FCMD/K taskkill/f/IM assumer.exe & assumer.exe 2. after completing the preceding operations, you can drag the desktop icon or programs in other paths to the Windows 7 taskbar. After dragging the desktop icon to the taskbar, the "attach to Taskbar" prompt appears, when you right-click the icon in the Windows 7 taskbar, the "unlock this program from the taskbar" command is returned, so that you can add or remove programs on the taskbar at will.
