Cygwin DLL or any package which contains the currently running executable from the Cygwin itself. There is also this note on the Cygwin Installation page: 'The basic reason for not having a more full-featured package manager is that such a program would need full access to all of Cygwin’s POSIX functionality. Running the Cygwin installer. If you plan to install Cygwin on another PC, however, you may be able to save time by copying the local package directory and the Cygwin installer to the second PC; follow these instructions to install Cygwin on the second PC, but choose 'Install from Local Directory' in step 3.

General installation notes
When installing packages for the first time, setup*.exedoes not install every package. Only the minimal base packagesfrom the Cygwin distribution are installed by default, which takes up about 100 MB.
Clicking on categories and packages in the setup*.exe package installationscreen allows you to select what is installed or updated.
Individual packages like bash, gcc, less, etc.are released independently of the Cygwin DLL, so the Cygwin DLL version is notuseful as a general Cygwin release number. The setup*.exe utilitytracks the versions of all installed components and provides the mechanismfor installing or updating everything available from this site forCygwin.
Once you've installed your desired subset of the Cygwin distribution,setup*.exe will remember what you selected so rerunning theprogram will update your system with any new package releases.
On Windows Vista and later, setup*.exe will check bydefault if it runs with administrative privileges and, if not, will tryto elevate the process. If you want to avoid this behaviour and installunder an unprivileged account just for your own usage, runsetup*.exe with the --no-admin option.
Q: How do I add a package to my existing Cygwin installation?
A: Run the setup program and select the package you want to add.
Tip: if you don't want to also upgrade existing packages, select 'Keep' at thetop-right of the package chooser page.

Q: Is there a command-line installer?
A: Yes and no. The setup*.exe program understandscommand-linearguments which allow you to control its behavior and chooseindividual packages to install. While this provides some functionalitysimilar to such tools as apt-get or yum it is not asfull-featured as those package managers.
Q: Why not use apt, yum, myfavourite package manager, etc.?
A: The basic reason for not using a more full-featured package manager is thatsuch a program would need full access to all of Cygwin's POSIX functionality. Thatis, however, difficult to provide in a Cygwin-free environment, such as exists onfirst installation. Additionally, Windows does not easily allow overwriting ofin-use executables so installing a new version of the Cygwin DLL while a packagemanager is using the DLL is problematic.
Q: How do I install everything?
A: You do not want to do this! This will install an enormous number of packagesthat you will never use, including debuginfo and source for every package.
If you really must do this, clicking on the 'Default' label next to the'All' category to change it to 'Install' will mark every Cygwin package forinstallation. Be advised that this will download and install tens of gigabytesof files to your computer.
Q: How do I verify the signature of setup?
A: e.g.
Q: What's the hash of setup?
A: See here
Q: How do I help improve setup?
A: See the setupproject page for more information.
