3.7.1.2 Tuning Microsoft Windows 7 Image for VDI
When many Windows desktops run on a hypervisor it is necessary to try to reduce unnecessary CPU cycles and
disk I/O to improve system performance and stability. By turning off unnecessary processes and other unwanted
desktop services for instance helps achieve this.
The following configurations were made to the standard image:
●
Configure fixed 1.5GB page file
●
Configure Networking and Firewall
◦ Turn off firewall
◦ Set DNS IP addresses for domain
◦ Turn off IPV6
●

the latest Forensic User Profile Manager tool, visit http://www.forensit.com/desktop-management.html
