Once you're ready to install Qubes OS on a live machine, here are the settings for getting rid of annoyances and for updating your system qubes.
Annoyances
System Beep Sound
On some systems, you'll hear an annoying beep sound on some menus, especially the logoff/shutdown menu. This seems to be more of an Xfce issue than a Qubes OS issue. The easiest way to get rid of it is to ..:
Open the Qubes OS Menu
Click the settings gear icon
Click Other
Open Xfce Terminal
Type xset b off
Hit enter
Close the Xfce Terminal window
Updates
The most important thing after the installation is getting the latest updates for all the subsystems that run the separate qubes (Whonix, Debian, Fedora). Although this is the latest version of Qubes OS, the underlying operating systems for the qubes need to be up-to-date as well:

These settings depend on your preferences:
Open the Qubes OS Menu
Click the settings gear icon
Click System Settings

Navigate back to the main menu by clicking the < All Settings button.
