Comment VirtuaWin (Score 2, Insightful) 359
Working as a desktop support with 30+ windows/apps open at the time calls for virtual desktops, I have tried Sys internals desktops - fail, tried VirtuaWin and haven't look for any other replacement. Can have virtual desktops setup as I like, can have one window shown at all desktops, another window always at the top etc. etc. The best tool I have used :) Did i mention that virtuawin is packaged as a portable app (portableapps) = even easier to deploy and use when you are unprivileged user.
