Patent number: 11074323Abstract: Securely performing file operations. A method includes determining a licensing characteristic assigned to a file. When the licensing characteristic assigned to the file meets or exceeds a predetermined licensing condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the guest operating system. When the licensing characteristic assigned to the file does not meet or exceed the predetermined licensing condition, then the method includes performing the file operation on the file in the guest operating system while preventing the file operation from being performed directly in the host operating system.Type: GrantFiled: June 21, 2018Date of Patent: July 27, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Benjamin M. Schultz, Balaji Balasubramanyan, Giridhar Viswanathan, Ankit Srivastava, Margarit Simeonov Chenchev, Hari R. Pulapaka, Nived Kalappuraikal Sivadas, Raphael Gianotti Serrano dos Santo, Narasimhan Ramasubramanian, Frederick Justus Smith, Matthew David Kurjanowicz, Prakhar Srivastava, Jonathan Schwartz

Patent number: 10885193Abstract: Securely performing file operations. A method includes determining a trust characteristic assigned to a file. When the trust characteristic assigned to the file meets or exceeds a predetermined trust condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the container operating system. When the trust characteristic assigned to the file does not meet or exceed the predetermined trust condition, then the method includes performing the file operation on the file in the container operating system while preventing the file operation from being performed directly in the host operating system.Type: GrantFiled: February 12, 2018Date of Patent: January 5, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Bryan R. Born, Giridhar Viswanathan, Peteris Ledins, Balaji Balasubramanyan, Margarit Simeonov Chenchev, Benjamin M. Schultz, Hari R. Pulapaka, Frederick Justus Smith, Narasimhan Ramasubramanian, Raphael Gianotti Serrano Dos Santo, Nived Kalappuraikal Sivadas, Ravinder Thind, Matthew David Kurjanowicz

Patent number: 8812970Abstract: Processes for presenting a current state of a device having device storage connected with a host system are provided. In some processes, device manufacturers or vendors define a set of operational states of a device and provide user interface (UI) elements of a custom representation of each state through information stored in the device storage. Initially, the set of states of the device and UI elements associated with each state are received from the device storage. Information regarding a current state is received from the device, and a representation of the current state, which includes the received UI elements, is presented on the host system. In other processes, UI elements of a representation of each state are obtained from a remote system using device identification information. In other processes, UI elements from the device, from the host system, and/or from a remote system are combined to form a state representation.Type: GrantFiled: February 27, 2008Date of Patent: August 19, 2014Assignee: Microsoft CorporationInventors: Robin Alexander, Vladimir Sadovsky, Narasimhan Ramasubramanian

Patent number: 8166515Abstract: A system is disclosed for centralized management of access permissions to unique class identifier devices on client terminals using a group policy framework. The system includes a first aspect whereby administrative templates related to the unique class identifier devices are used to configure a user interface allowing an IT administrator or other to set access permissions for the unique class identifier devices. The system further includes a second aspect for implementing the access permissions to the unique class identifier devices on the client terminals.Type: GrantFiled: October 30, 2006Date of Patent: April 24, 2012Assignee: Microsoft CorporationInventors: Emily N. Hill, Henry P. Gabryjelski, James C. Bovee, Narasimhan Ramasubramanian, Oren Rosenbloom, Robin A. Alexander

Patent number: 7171671Abstract: A method and system are provided for asynchronously providing interested applications of state changes in removable devices. A device driver polls the device associated with the driver for state changes. The state changes result in a change notification being generated. The driver provides the change notifications to the interested applications. The present invention also provides a change notification by a device driver to interested applications when a client application initiates a change in the device.Type: GrantFiled: August 23, 2001Date of Patent: January 30, 2007Assignee: Microsoft CorporationInventors: Robert R. Snead, Narasimhan Ramasubramanian
