LTSR and CR model

Citrix introduced two delivery options for Receiver for Windows – Long Term Service Release (LTSR) and current release. The recently released Receiver for Windows 4.4.2000 is the cumulative update on top of the Receiver for Windows 4.4 LTSR release, which includes only bug fixes and security fixes. Receiver for Windows 4.5 is the current release, which includes new features in addition to the bug fixes and security fixes.

Enabling the HDX enhancements from XenApp, XenDesktop 7.11

  • HDX 3D Pro now enables hardware encoding using NVIDIA’s NVENC technology. Receiver for Windows 4.5 supports the hardware-encoded graphics, which gives better scalability on the server with best possible quality.
  • Support for selective H.264 with the HDX Thinwire codec, that provides the benefit of lower bandwidth use for the video content combined with the sharpness of text in applications elsewhere on the screen. In addition, there are optimizations in caching that result in further reduction in bandwidth requirement.
  • Relative mouse support improves the user experience of simulator applications. Users can enable the relative mouse support on the fly in a desktop session from the desktop viewer toolbar.
  • Twain 2.0 support lets users access image processing applications, which use the TWAIN 2.0 scanning protocol over XenApp and XenDesktop
  • USB Audio per user setting: Now audio devices can be used simultaneously in a Xenapp and XenDesktop session via USB redirection and optimized audio devices. USB audio devices that can be redirected can now be configured on a per user basis, so that the user can control how to use the devices.

Simplified configuration

SSON Configuration check:
