Optimizing Window7 for VDI Overview
Deploying Microsoft Windows 7 Virtual Desktops with VMware View Applied Best Practices
9
This applied best practices guide provides a set of implementation guidelines to increase virtual
machine performance and reduce the I/O burden of the OS significantly. This can also reduce the
amount of storage required to support the VDI infrastructure, which in turn, can reduce the initial
capital expenditure and operational expenditure outlays. These reductions can significantly
increase the return on investment (ROI) of the solution.
Many of the configuration adjustments described in this guide can substantially improve the
performance of a virtual machine. However, performance comes at the cost of features. It is the
responsibility of the desktop engineering team to find a suitable balance between the features
required by users and the performance of their environment.

This guide assumes that a Microsoft Windows domain that is running on Windows Server 2008
R2 is configured to house the VMware View
users and desktops.

any of the optimizations mentioned in this guide are accomplished by using Microsoft Active
Directory (AD) Group Policy Objects (GPO) or by editing the registry directly. Use the AD
GPOs to manage user desktops that log in to the same virtual desktop. This practice allows
administrators to enforce domain policies on the desktops even if users are given the necessary
permissions to make changes to the local policy of their machines.
For deployments where user changes are discarded after logging off, use local policy objects
(LPO) in the master image instead of AD-based GPOs. When administrators use LPOs instead of
GPOs, they have the ability to significantly reduce the load on domain controllers at higher
desktop counts.
Do not implement desktop policy directly through the registry. This method is prone to error and
high management overhead.
