Disable Microsoft Feeds Synchronization on Windows 7 Virtual Machines
Windows Internet Explorer 7 or 8 uses the Microsoft Feeds Synchronization task to update RSS feeds in users'
Web browsers. This task can contribute to linked-clone growth. Disable this task if your users do not require
automatic RSS feed updates in their browsers.
Microsoft Feeds Synchronization can cause OS-disk growth if persistent disks are not configured. If persistent
disks are configured, the impact is diverted to the persistent disks. In this situation, you should still disable
Microsoft Feeds Synchronization to control persistent-disk growth.
Procedure
1 In vSphere Client, select the parent virtual machine and select Open Console.
2 Log in to the Windows 7 guest operating system as an administrator.
3 Click Start > Control Panel > Network and Internet > Internet Options.
4 Click the Content tab.
5 Under Feeds and Web Slices, click Settings.
6 Deselect Automatically check feeds and Web Slices for updates and click OK.
7 In the Internet Properties dialog, click OK.
Preparing Virtual Machines for View Composer
To deploy linked-clone desktops, you must prepare a parent virtual machine that meets the requirements of
the View Composer service.
n
Prepare a Parent Virtual Machine on page 65
The View Composer service requires a parent virtual machine from which you generate a base image
for creating and managing linked-clone desktops.
n
Activating Windows 7 and Windows Vista on Linked-Clone Desktops on page 66
To make sure that View Composer properly activates Windows 7 and Windows Vista operating systems
on linked-clone desktops, you must use Microsoft volume activation on the parent virtual machine. The
volume-activation technology requires a volume license key.
n
Disable Windows Hibernation in the Parent Virtual Machine on page 66
The Windows hibernation option creates a large system file that can increase the size of the linked-clone
OS disks that are created from the parent virtual machine. Disabling the hibernation option reduces the
size of linked-clones.
n
Configure a Parent Virtual Machine to Use Local Storage on page 67
When you prepare a parent virtual machine for View Composer, you can configure the parent virtual
machine and linked-clone desktops to store virtual-machine swap files on the local datastore. This
optional strategy lets you take advantage of local storage.
n
Keep a Record of the Parent Virtual Machine's Paging-File Size on page 68
When you create a linked-clone pool, you can redirect the linked clones' guest OS paging and temp files
to a separate disk. You must configure this disk to be larger than the paging file in the guest OS.
n
Increase the Timeout Limit of QuickPrep Customization Scripts on page 69
View Composer terminates a QuickPrep post-synchronization or power-off script that takes longer than
20 seconds. You can increase the timeout limit for these scripts by changing the ExecScriptTimeout
Windows registry value on the parent virtual machine.
