Desktops reliance on Windows desktop objects means that it cannot provide some of the functionality of other virtual desktop utilities, however. For example, Windows doesn't provide a way to move a window from one desktop object to another, and because a separate Explorer process must run on each desktop to provide a taskbar and start menu, most tray applications are only visible on the first desktop. Further, there is no way to delete a desktop object, so Desktops does not provide a way to close a desktop, because that would result in orphaned windows and processes. The recommended way to exit Desktops is therefore to logoff.

Wow is this a minimal app. It basically does what it says it does, and not an ounce more. Not that I want bells-and-whistles just for the sake of having them. But it would be nice to have, For example, a one-click method to switch desktops (it currently requires one click to bring up a choice of desktops, then a click to select one). Other simple features that this app does not support include: , naming desktops, customize the number of desktops (well, this is supported, but it isn't very mature implementation), auto-assigning certain applications to launch in certain desktops.

For those of us still using Win 7 (and, in the year 2016, there are plenty of enterprises that have not yet allowed win 8 or win 10 on their corporate computers), this app is OK. I prefer Dexpot, but you can certainly use this one to achieve virtual desktops.
