This chapter covers the following subjects:

Optimizing the Operating System
Configuring Virtual Hardware
Installing the Agent
Creating Customization Specifications

(This chapter covers Objective 3.5 of the Blueprint.)

Up to now, we have reviewed the steps necessary to install and configure View, and to provide an optimal delivery experience for users connecting to virtual desktops. However, for the best possible end-user experience, the virtual desktop itself must also be optimized. The first step in this optimization process is fine tuning the operating system (OS) to function well in a View environment. Windows operating systems were not initially designed for a virtual platform. Although they have been adapted in recent years to function in this type of environment, changes should still be made to ensure that they perform well. For example, in a virtualized environment, all components of a desktop exist as files. Therefore, optimizing storage resources when virtualizing a desktop is a critical step in ensuring proper performance. Some of these optimization steps are simple tricks that can result in an impressive performance improvement, not only for virtual environments but for physical environments as well. This chapter takes a look at these optimization methods.
