We see three types of installation modes:
- Install from the Internet, this mode is installed directly from the Internet, suitable for fast speed situation;
- Download without installing, this mode only downloads the Cygwin component package from the Internet, but does not install;
- Install from local Directory, this mode corresponds to the second mode above, and when your Cygwin component package has been downloaded locally, you can use this mode to install Cygwin locally.
From the above three modes, I choose the first installation mode, directly from the network installation, of course, while downloading, Cygwin components are also saved to the local, so that later can be installed again. When selected, click Next,
This step selects the installation directory for the Cygwin, as well as some parameter settings. The default installation location is C:\cygwin\, you can also choose your own installation directory, and then choose "Next",

In this step, we need to note that in order to get the fastest download speed, we first look for the address of the Cygwin Chinese image in the list: http://www.cygwin.cn, if found, select this address; If you cannot find this address, enter the address of the Chinese mirror manually: http ://www.cygwin.cn/pub/, then click "Add" and then select it in the list. After selecting Done, click "Next",
