Mark Russinovich and Bryce Cogswell have recently released a Desktops application as part of the Sysinernal Suite. Desktops allows you to organize your applications on up to four virtual desktops. Read email on one, browse the web on the second, and do work in your productivity software on the third, without the clutter of the windows you’re not using. Unix users are usually familiar with this feature and have it built in their UI frameworks. But in Windows it was always missing.
Especially nice that it comes in one file of 117KB size and requires no installation.
Thanks to LiM for first sharing this stuff.
