Setting Up a New PC?
This is the original use of Ninite. Just go to http://ninite.com and select the apps you want, click “Get Installer”, and then run the Ninite installer .exe.
Ninite downloads and installs all your choices with no clicking Next. It even says “No” to toolbars and other junk.
Keeping Apps Up-to-Date
Ninite installers always install the latest versions of apps regardless of when they were created. This means that after you install some apps with Ninite you can keep the installer .exe around and run it again every now and then to keep those apps updated.
Ninite checks app versions before downloading and installing software. So if you already have the latest version Ninite will just keep moving down your list of apps.
