How do I add an icon to the "Quick Start" bar in Windows 7? Some friends have reflected this situation. It is the one next to "start". I dragged the icon to the top, no.
Right click and lock to the taskbar. Generally encountered such a problem we will want to escape if you can not drag, indicating that your program is running, there is a display on the taskbar. When you open the computer, the icon of the resource manager is displayed on the taskbar. If you want to display "computer", you can change it by changing the icon of the resource manager. This is the icon, I mean, when I close the "Computer" window, the folder icon can continue to be on the taskbar, so it is convenient to open the computer next time.
Step 1: First right click on the blank space of the taskbar, in the pop-up menu, uncheck the "Lock Taskbar". Uncheck the selected taskbar.
Step 2: Right click the mouse in the blank space of the taskbar, and then open "Toolbar" → "New Toolbar". A file dialog will pop up, copy “%appdata%MicrosoftInternet ExplorerQuick Launch” to the empty space after the “folder” of the dialog box (enter the double quotes when you enter) to point to the quick launch bar.
After the input is complete, click "Select Folder" and you will find that the Quick Launch Bar has returned to the taskbar. However, at this time, the quick launch bar is not in the lower left corner that everyone is familiar with. Please use the left mouse button to select "Quick Launch" to the left (near the start menu), and finally release the mouse.
But this time the quick launch bar is not "perfect", you will find that each icon in the launch bar takes up a long string of space because of the text. The solution is to right-click on the taskbar and uncheck "Show Text" and "Show Title". Icons such as the computer recycle bin need to be placed on the taskbar in a special way.
Other programs can be dragged and dropped directly. If the program is running, you can right click on the icon on the taskbar to select to lock to the taskbar. I wish you all the best.
