VMware OS Optimization Tool

The VMware OS Optimization Tool provides the necessary information for optimizing a Windows virtual desktop or server master image for use in View in Horizon 6 or Horizon 7, or in Horizon Air Cloud-Hosted. The document is a companion to the VMware OSOT Fling (Operating System Optimization Tool). The document describes optimizations for Windows 7, Windows 8, Windows 10, Windows Server 2008, and Windows Server 2012. The optimization tool includes customizable templates to enable or disable Windows system services and features, per VMware recommendations and best practices, across multiple systems. Since most Windows system services are enabled by default, the optimization tool can be used to easily disable unnecessary services and features to improve performance.
These recommended optimizations enhance the overall scalability and performance within a View virtual desktop infrastructure or Horizon Air cloud tenant environment.

You can perform the following actions using the VMware OS Optimization Tool:

  • Local Analyze/Optimize
  • Remote Analyze
  • Optimization History and Rollback
  • Managing Templates


  • Windows 7, Window 8, Windows Server 2008 R2, Windows Server 2012, Windows 10(Beta)
  • NET Framework 3.5, SP1.

Note: .NET 4.0 does not cover .NET 3.5 SP1. If you have only .NET 4.0 or 4.5 installed, you still need to install .NET 3.5 SP1. By default .NET 3.5 is installed on Windows 7. For Windows Server 2008 r2, it’s a Windows feature and you can enable it without additional download.
