Embodiment Construction

[0078] 1.0 Overview of the isolation environment concept

[0079] 1.1 Application Isolation

[0080]Referring now to FIG. 2A , one embodiment of a computer operating under the control of an operating system 100 in which application compatibility and application sociability issues have been reduced is shown. Operating system 100, via its system layer 108, makes various native resources available to applications 112, 114. The view of resources comprised by the system layer 108 will be referred to by the term "system-wide". In order to avoid conflicts between applications 112, 114 accessing native resources 102, 104, 106, 107, an isolation environment 200 is provided. As shown in FIG. 2A , the isolation environment 200 includes an application isolation layer 220 and a user isolation layer 240 . Conceptually, isolation environment 200 provides applications 112 , 114 via application isolation layer 220 with a unique view of native resources such as file system 102 , registry 104...

Abstract

A method for moving an executing process from a source isolation scope to a target isolation scope includes the step of determining that the process is in a state suitable for moving. The association of the process changes from a source isolation scope to a target isolation scope. A rule loads in association with the target isolation scope.

Description

technical field [0001] The present invention relates to managing the execution of software applications by computers, and in particular to methods for reducing compatibility and sociability problems between different applications and between individual users of the same application executed by the same computer system methods and equipment. Background technique [0002] Computer software applications, during execution and installation, take advantage of various native resources provided by the computer's operating system. A conventional single-user computer is depicted in Figure 1A. As shown in FIG. 1A , native resources provided by operating system 100 may include file system 102 , registry database 104 and objects 106 . The file system 102 provides mechanisms for applications to open, create, read, copy, modify, and delete data files 150,152. Data files 150, 152 may be grouped together in a logical hierarchy of directories 160, 162. Registry database 104 stores various...
