<p>You can prevent a user from installing additional software on the system.
They will still be able to search for new software to install, but will need
an administrator to authorize the installation when they try to install an
application. This applies whether they are trying to install the application
system-wide (for all users) or just for themselves.</p>
<p>Additionally, you can restrict which software a user can browse or search
for in the <app>Software</app> catalog by age categories.</p>

</steps>
<p>The <gui style="checkbox">Restrict Application Installation for Others</gui>
checkbox allows the user to install additional software for themselves, but
prevents that software from being made available to other users. It could be
used, for example, if there were two child users, one of whom is mature
enough to be allowed to install additional software, but the other isn’t —
enabling <gui style="checkbox">Restrict Application Installation for Others</gui>
would prevent the more mature child from installing applications which are
inappropriate for the other child and making them available to the other
child.</p>
