The invention provides an
application virtualization window smooth dragging method, a
client side and a
server side, and the method comprises the steps that the
client side establishes channel connection with the
server side, and a virtualized application under an
operating system of the
server side is started; receiving a
mobile message of the application sent by the server, wherein the
mobile message is used for indicating an application window of the
client to move; moving an application window to a target position in real time, and
synchronizing information of the application window to the server; and receiving the final position of the application window notified by the server, carrying out on-screen
processing, and redrawing and refreshing a target window. The application of the remote service desktop can be started at the client, it is guaranteed that no residue exists in the moving process of the application window, and the user experience same as that of an original desktop is achieved.
