Abstract: A method for bridging between virtual applications and an operating system of a host computer. The method comprises retrieving virtual applications and settings of the virtual applications assigned to a user logged onto the host computer, wherein each of the virtual applications includes the following files: a virtual engine, a user data file, and an application-on-demand (AOD) file; downloading shadow files of the virtual applications assigned to the user; integrating each of the virtual applications with an operating system shell of the host computer; and causing a virtual application to be executed over the host computer when the virtual application is launched by the user.

Abstract: A method and system for capturing and transmitting screen content and input/output events from a server to a client device are provided. The method includes transmitting, to the client device, a screen output rendered by the server respective of a first instance of a first application; and transmitting, to the client device, the screen output rendered by the server respective of a second instance of a second application, wherein the first instance is contained in a first securable object associated with the first application and the second instance is contained in a second securable object associated with the second application, wherein the first instance and the second instance are simultaneously executed by the server under a single logon session.

Abstract: Techniques for enabling writing and reading to and from a user file by at least a virtual software application. The user file includes a session file, an index file, and a data file. The techniques enable roaming between computers without the need to reconfigure, for example, the personalized information when switching between computers.

Abstract: A method for cross-operating systems execution of a legacy software application on a user computing device is provided. The method comprises upon launching a native application on the user computing device, executing, on a server, a cloudified application corresponding to the legacy software application, the legacy software application is compliant with a first operating system, wherein the user computing device is compliant with a second operating system, the first operating system and the second operating system are incompatible with each other; rendering outputs responsive of inputs generated by the native application and received at the cloudified application; streaming the rendered outputs to the user computing device to be displayed by the native application; and performing file system operations requested by at least one of the native application and the cloudified application on at least a cloud storage service.

Abstract: A method for enhancing functionality of locked-down computers by allowing installation of software applications on the locked-down computers operated by users having limited administrator permissions. The method comprises detecting an attempt for installation of a software application on a locked-down computer; generating a virtual software application corresponding to the software application, wherein the virtual software application is generated in a virtual environment; and enabling the execution of the virtual software application in the virtual environment.
