Abstract: Embodiments are directed to efficiently provisioning applications in a multi-user environment. In one scenario, an administrator computer system pre-installs at least a portion of a software application on a data image, where the software application is to be installed on a client computer system upon receiving a notification from a computer administrator. The administrator computer system receives an input from the computer administrator indicating that a specified software application pre-installed on the client computer system's data image is to be installed on the client computer system. The administrator computer system then publishes a notification to the client computer system indicating that a specified software application pre-installed on the client computer system's data image is to be installed. Upon receiving the notification, the software application is installed on the client computer system from the data image.

Abstract: Exemplary techniques for enabling single sign-on to an operating system configured to conduct a remote presentation session are disclosed. In an exemplary embodiment, a user credential can be encrypted using an encryption key generated by a remote presentation session server and sent to a client. The client can send the encrypted user credential to the remote presentation session server. The remote presentation session server can decrypt the user credential and use it to log a user into an operating system running on the remote presentation session server. In addition to the foregoing, other techniques are described in the claims, the detailed description, and the figures.

Abstract: Techniques are provided for preserving state—both machine state and user state—in a virtual machine (VM) in a server deployment. User state may be preserved among a plurality of VMs in a server deployment by storing data specific to the user in a virtual hard drive (VHD). When a user logs into a particular VM, the VM remaps portions of a guest OS file system that correspond to user state to the VHD and mounts the VHD. Machine state may be preserved by storing information particular to a VM apart from that VM. When a VM is to be recreated, a diff disk containing the information particular to the VM is determined based on the current VM, the information particular to the VM, and a gold image that the VM is to be created with. Then, the VM is created with the gold image and the diff disk.

Abstract: A method of acquiring software profile information of a target software application includes receiving a programmed interrupt while executing an application in a computer system, servicing the interrupt such that call stack information is acquired and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. Some or all of the call stack information may be recorded. The statistical information includes statistics concerning the number of samples wherein a series of functions calls are included in the call stack information and the number of samples wherein a set of function calls are at the top of the call stack information.

Abstract: A method of acquiring software profile information of a target software application includes Monitoring an application program for system calls, detecting a system call of interest to the user, acquiring stack information, and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. The call stack information may be recorded. The statistical information includes statistics concerning the number of samples that any one function call is at a top of the call stack information, the number of samples that a series of functions calls are included in the call stack information, and the number of samples that a set of function calls are at the top of the call stack information.
