The disclosure is directed to systems, apparatus, and methods for layered execution pre-boot configuration. In one example, a system includes a local computer, a base operating system, a layered execution environment, and a layered environment manager. The system may further include an environment update service and one or more layered environment data store(s). The system may, before booting the base operating system and layered execution environment, perform such modification operations as applying an operating system patch, applying a program patch, changing a layer activation property, disabling a program, replacing a program, changing a configuration file, and installing a driver.

The disclosure is directed to computing systems that provide access to the content of layers. Layers may include, for example, application layers, baseline layers, data layers, patch layers, application patch layers, and sublayers. Prioritization schemes, including prioritization by layer type, by assigned priority weights, by access type, by sub-layers and by read-write indicators are provided. Layers may contain file reference information including exclusion or inclusion entries indicating what files may be written. Paths recorded in layers may also embed variables to true paths on a layered system. Detailed information on various example embodiments are provided in the Detailed Description, and the invention is defined by the appended claims.
摘要:
The inventions relate generally to protection of computing systems by isolating intrusive attacks into layers, those layers containing at least file objects and being accessible to applications, those layers further maintaining potentially intrusive file objects separately from regular file system objects such that the regular objects are protected and undisturbed. Also disclosed herein are computing systems which use layers and/or isolation layers, and various systems and methods for using those systems. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
摘要:
A directory services system includes a resource object, such as an application object for accessing an actual resource associated with the resource object. Rights attributes of the resource object reflects information for controlling rights of a user (or entity) to access the actual resource. The rights attributes may include criteria for distribution. The rights attributes may be used to rapidly, dynamically, remotely, and easily define and control access to available instances of a resource object based on certain criteria, such as organization, membership, etc. A utility (snap-in) module may be relied upon to manage the values of the attribute. Application programming interfaces (executables) in a dynamically linked library may be provided to "consume" (use) the attributes in the resource objects stored in directory services database.
摘要:
A computer-implemented method for defragmenting virtual machine prefetch data. The method may include obtaining prefetch information associated with prefetch data of a virtual machine. The method may also include defragmenting, based on the prefetch information, the prefetch data on physical storage. The prefetch information may include a starting location and length of the prefetch data on a virtual disk. The prefetch information may include a geometry specification of the virtual disk. Defragmenting on physical storage may include placing the prefetch data contiguously on physical storage, placing the prefetch data in a fast-access segment of physical storage, and/or ordering the prefetch data according to the order in which it is accessed at system or application startup.

The disclosure is directed to automatic virtualization based on user-defined criteria. In one example, data representative of user-defined criteria is received, a virtualization heuristic is generated based on the user-defined criteria, the virtualization heuristic is activated, an occurrence of an event defined by the user-defined criteria is detected, and at least one virtualization operation is automatically performed in response to the detected event. In certain embodiments, the virtualization operation is selected based on the user-defined criteria. In certain embodiments, the virtualization operation includes capturing file system and configuration activity associated with the detected event and storing data representative of the captured file system and configuration activity to a virtual layer.

The inventions relate generally to portable media storage devices that contain layers permitting applications to be used at a connected computing device, those systems optionally including drivers for operating a layered computing environment or a driver installation program. Also disclosed herein are computer systems for using other systems for creating those portable storage devices. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
摘要:
A directory services system includes resource objects, such as an application object for accessing a resource associated with the resource object. Foldering attributes may be provided or added to an existing or new, specialized resource object. Foldering attributes reflect correspondence of the actual resources to an organizational scheme. The foldering attributes may include not only linking and backlink information, but management data for multiple levels of linking and organization, all stored in a Network Directory Services resource object. A resource, via its resource object in the directory services database, may be easily assigned to an organizational position for an individual user, a group, container, or the like. A snap-in module may be created, having executables as one or more Application Programming Interfaces (API's) in a Dynamic Link Library (DLL) for consuming (using) the foldering attributes. A utility may be provided in the Directory Services Systems' Administration module, or as on of such modules, to create and manage the foldering attributes. In certain embodiments attributes may be in objects requiring no methods embedded therein. In other embodiments methods in resource objects may contain additional executables or even obviate API's in the DLL.
摘要:
A file system includes first, second, third, and fourth directories where the first and second directories are sub-directories of the third directory, the third directory is a sub-directory of the fourth directory, the first directory stores only files identified by a first file extension, the second directory stores only files identified by a second file extension, and the first and second file extensions are distinct. A method involves receiving first and second requests to open first and second files, respectively, that are contained in the file system. The first and second requests include first and second file system paths, respectively. The first file system path is modified by adding identities of the first, third, and fourth directories to the first file system path. The second file system path is modified by adding identities of the second, third, and fourth directories to the second file system path.
摘要:
The disclosure is directed to dynamic insertion and removal of virtual software sub-layers. In one example, a virtual layer associated with a software application is virtually installed and activated in a computing device. A virtual sub-layer associated with a component of the software application is dynamically inserted in the virtual layer. The virtual layer remains active during the dynamic insertion of the virtual sub-layer. In certain embodiments, a process is executed from the virtual layer, a determination is made as to whether the process launched before or after the insertion of the virtual sub-layer, and the inserted virtual sub-layer is selectively made visible or invisible to the process based on the determination.
