Most Linux distributions provide a [[package management system|program]] program, such as [[Synaptic (software)|Synaptic]] or [[PackageKit]], for browsing a list of thousands of [[free software]] applications that have already been tested and configured for a specific distribution. These free programs can be downloaded and installed with one mouse click.<ref name="Debian01">{{cite web|url = http://wiki.debian.org/Synaptic|title = Debian Wiki - Synaptic|accessdate = 2008-10-11|last = Debian|authorlink = |year = 2008|month = May}}</ref> A digital signature guarantees that the program was not modified after the download package was created and the [[package manager]] automatically tracks and installs updates as they become available.<ref name="Debian02">{{cite web|url = http://wiki.debian.org/SecureApt|title = Debian Wiki - secure apt|accessdate = 2008-10-11|last = Debian|authorlink = |year = 2008|month = September}}</ref>
Besides the free Windows compatibility layer [[Wine (software)|Wine]], most distributions offer [[dual boot]] and [[x86 virtualization]] for running both Linux and Windows on the same computer.
