微软在几年前为自己的PowerToys组件里添加了一个virtual desktop manager( MSVDM )，使得XP用户及XP以前版本的用户体验到了多个虚拟桌面的感觉，然而在最新OS里面，MSVDM并不为他们提供支持。所以想使用MSVDM的朋友，只能使用XP或以前版本了（虽然2000也不错，但现在不会使用它。。。）
或许是听到了群众的呼声吧，在今年8月份，微软又推出了一款小软件：desktops，终于可以象在linux下一样使用虚拟桌面了。这是一款缺点和优点同样明显的软件：
优点是：
- 文件很小，而且绿色
- 支持启动的时候加载
- 快捷键虽然固定，但相对比较灵活
缺点是：
- 只能设四个虚拟桌面，不能是三个或者2个
- 每个虚拟桌面都是一个独立的explorer进程，内存小的朋友尽量不要尝试
- 虚拟桌面出错的时候，由于独立进程explorer并没有关闭，所以你打开的软件，是找不到的。非得再运行一下这款软件

Introduction
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. After you configure hotkeys for switching desktops, you can create and switch desktops either by clicking on the tray icon to open a desktop preview and switching window, or by using the hotkeys.
Using Desktops
Unlike other virtual desktop utilities that implement their desktops by showing the windows that are active on a desktop and hiding the rest, Sysinternals Desktops uses a Windows desktop object for each desktop. Application windows are bound to a desktop object when they are created, so Windows maintains the connection between windows and desktops and knows which ones to show when you switch a desktop. That making Sysinternals Desktops very lightweight and free from bugs that the other approach is prone to where their view of active windows becomes inconsistent with the visible windows.
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.
