Why Windows 7 can't find the quick launch bar

Q: Why can't I find the quick launch bar in Windows 7 system?
A: After the system is installed, there is no quick launch bar by default, but it does not mean that Windows 7 does not have this function. Actually, Windows 7 is fast. The launch bar and taskbar are merged. If you want to implement the quick start function, just drag the shortcut of the program to the left side of the taskbar (next to the start menu button). At the same time, according to Win+1, 2, 3, etc., the corresponding first, second, third, etc. programs can be started. The newly opened window of the program will also be superimposed directly on the icon to form a task heap.
