Like the title says - if you have any tips & tricks that will help get the most of the systems, here's a place for them. For starters:
If you're coming back to UCD, you'll find all the PCs have been upgraded to Windows 7. The Desktop is now locked, and you can no longer put anything on it - but if you had anything on there last semester, it's still available in H:\Desktop. Your new default "My Documents" folder is H:\Documents, but all your old files will still be in H:\Personal.
The PCs are locked down, and you can't install anything on them yourself. You can, however, install
PortableApps on a USB drive, or even to H: if you have the free space. If you do, I recommend starting with the
PortableApps Platform, which has a menu and an automatic updating system for your PortableApps. Performance from slow USB drives can be ... slow - YMMV.
The new UCD Mail system runs on the Google Gmail platform. If you already use Gmail, it's helpful to enable Multiple Sign-In on
both accounts, so you can have both going at the same time. When logged in, go to your Google settings (top right), Account Settings, then enable it there under "Security".
