When installing packages the first time, setup*.exe won't install every package. Only the minimal base packages from your Cygwin distribution are installed automagically, that can up about 100 MB.
Clicking on categories and packages from the setup*.exe package installation screen lets you select precisely what is installed or updated.
Individual packages like bash, gcc, less, etc. are freed independently from the Cygwin DLL, therefore the Cygwin DLL version will not be useful like a general Cygwin release number. The setup*.exe utility tracks the versions coming from all installed components and supplies the mechanism for installing or updating everything made available from this site for Cygwin.
Once you've installed your desired subset with the Cygwin distribution, setup*.exe will remember whatever you selected so rerunning this course will remodel your system with any new package releases.
On Windows Vista and later on, setup*.exe will check automagically if it runs with administrative privileges and, or even, will endeavor to elevate the method.

A: The basic reason behind not utilizing a more full-featured package manager is the fact such a program will need full usage of all of Cygwin's POSIX functionality. That is, however, tricky to provide inside a Cygwin-free environment, including exists on first installation. Additionally, Windows isn't going to easily allow overwriting of in-use executables so installing a brand new version on the Cygwin DLL while a package manager is utilizing the DLL is problematic.
A: You do not need to do this! This will install a massive number of packages that you will never use, including debuginfo and source for each package.
If you truly must do this, simply clicking the "Default" label next to the "All" category to vary it to "Install" will mark every Cygwin package for installation. Be advised until this will download and install tens of gigabytes of files for your computer.
