摘要： A directory that resides on a layered volume can be renamed. A hooking module can be employed to intercept rename requests. The hooking module can query a layering file system filter driver to determine the volume of the source and target of the rename request. If the source and target are on different volumes, thereby indicating that the source is a directory of a layered volume, the hooking module can append a signature to the target which identifies the actual volume of the source. The modified rename request can then be passed to the operating system which will perform its normal operations including verifying that the source and target are on the same volume. During this verification, the layering file system filter driver can detect the appended signature in the target and can inform the operating system that the target is on the volume identified in the signature.

摘要： Multiple clipboard items are supported in a VDI environment. A client clipboard service can monitor the system clipboard to detect when a clipboard item is added to the system clipboard. The client clipboard service can copy any item added to the system clipboard to a client clipboard buffer. The client clipboard service can also interface with a client virtual channel endpoint to send items in the client clipboard buffer to a server virtual channel endpoint. A server clipboard service can then copy the received items to a server clipboard buffer to thereby synchronize the client and server clipboard buffers. The server clipboard service can function in a similar manner to copy items added to the server's system clipboard to the server clipboard buffer and then interface with the server virtual channel endpoint to cause such items to be synchronized back to the client clipboard buffer.

摘要： Source devices can be secured using a display device filter. When a display device is connected to a source device, a display device filter can identify the display device and determine whether it is a trusted display device. If the display device filter determines that the display device is not trusted, it can take a number of actions to minimize the likelihood of harm to the source device. These actions may include preventing the source device from booting, shutting down the source device, locking the source device, blocking access to other devices, and/or notifying an administrator. In this way, a malicious user can be prevented from gaining access to the source device.

摘要： Data transfer can be optimized for redirected UASP devices. When a UASP device is connected to a client terminal that has established a remote session on a server, the VDI can use a network optimal transfer length in place of the actual MAXIMUM TRANSFER LENGTH and OPTIMAL TRANSFER LENGTH of the UASP device. As a result, the server will use the specified network optimal transfer length for requests sent to the redirected UASP device. These requests can therefore be sent to the client in an optimal manner. Then, to optimize the performance of the UASP device, the requests can be split on the client into multiple requests having the OPTIMAL TRANSFER LENGTH and then submitted to the UASP device. In this way, the VDI can optimize the transfer of requests over the network as well as the servicing of requests by the UASP device.

摘要： A smart card stub and a smart card proxy can be employed to enable a redirected smart card reader to be accessed within a remote session. To isolate a redirected smart card to a remote session, the smart card stub can be configured to process a response to an application's request to enumerate smart card readers. This processing can include obtaining a session identifier for each enumerated smart card reader and removing any smart card reader from the response if the session identifier of the smart card reader does not match the session identifier of the requesting application. The smart card stub can communicate with a filter driver to obtain the session identifiers employed in this process.

摘要： Peer assisted updates can be provided in a device management environment. When it is desired to deploy an update to a group of managed devices, an update command can be sent to a first set of managed devices in the group instructing these managed devices to download the update. Once these managed devices have downloaded and installed the update, they will notify the management server. In response, the management server can instruct these managed devices to remain awake so that they may each function as a master device or repository for deploying the update to other managed devices in the group. The management server can then send update commands to the other managed devices instructing them to download the update from one of the managed devices that is now acting as a master device. This process can be repeated until all managed devices in the group have been updated.

摘要： Live imaging of a device can be performed. A client device can include at least two drives that are alternately employed to store the active OS partition. An imaging solution that executes on the active OS partition on a first drive can perform a live imaging process in which a second drive is fully imaged while the user continues to use the client device. Then, once the imaging of the second drive has been completed, the client device can be rebooted to cause the client device to boot from the second drive. In this way, the only downtime that a user may experience due to the imaging process is during the reboot. In a similar manner, when a client device includes only a single available drive, the drive can be divided into two or more sets of one or more partitions that are alternately employed as the active OS partition(s).

摘要： Examples of methods, systems, apparatus, and machine-readable storage media are provided to facilitate access and control of a remote desktop of a remote machine by a web browser at a client device through a transcoding server without installing proprietary plug-ins or protocols on the client device. A transcoding server may translate user input requests from a web browser into input calls compatible with a remote desktop display protocol. The transcoding server may receive remote desktop drawing commands from the remote machine and translate the remote desktop drawing commands into web browser drawing updates compatible with the web browser. A transcoding server may communicate with is web browser via HTTP and communicate with a remote machine via a remote desktop display protocol. A web browser may be an HTML5 browser. A transcoding server may send drawing coordinates to the web browser via an HTTP header and may use long polling.

摘要： A non-USB device can be virtualized as a USB device. When a non-USB device is connected to a client terminal, a filter driver can be employed to cause the non-USB device to be treated as a USB device to thereby allow the device to be redirected using USB device redirection techniques. When an I/O request is sent to the redirected device, the request will be in USB format since the server-side components will view the redirected device as a USB device. Then, the I/O request can be converted from the USB format into a format suitable for the non-USB device. Any response generated by the non-USB device can be converted to USB format in a similar manner. As a result, non-USB devices can be redirected without altering any of the existing server-side VDI components.

摘要： The processing of a first data stream to generate a second stream conforming to a remote desktop protocol (RDP) is described. Operations may include facilitating storage of first data from the first stream at a first index indicated is the first stream, facilitating retrieval of second data from a second index included in the first stream, and facilitating generation of the second stream conforming to the RDP and including the first and second data. Additionally, the processing of a third data stream conforming to the RDP to stream a fourth stream is described. Operations include facilitating processing of the third stream to identify a package data unit (PDU), facilitating storing of a hash value corresponding to the PDU, and facilitating generating an altered PDU for inclusion in the fourth stream and including an index identifying a location in memory storing the hash value.
