Disable Windows Registry Backup on Windows 7 and Windows 8 Virtual
Machines
Disabling the Windows registry backup feature, RegIdleBackup, can minimize the number of system writes
and reduce the growth of linked-clone machines.
Procedure
1 In vSphere Client, select the parent virtual machine and select Open Console.
2 Log in to the Windows 7 or Windows 8 guest operating system as an administrator.
3 Click Start > Control Panel > System and Security > Administrative Tools.
4 Select Task Scheduler and click Open.
5 In the left pane, expand Task Scheduler Library, Microsoft, Windows.
6 Double-click Registry and select RegIdleBackup.
7 In the Actions pane, click Disable.
Disable the System Restore on Windows 7 and Windows 8 Virtual Machines
You do not need to use the Windows System Restore feature if you use View Composer refresh to restore
linked-clone OS disks to their original snapshots.
When the operating system is idle, System Restore does not have a visible impact on OS-disk growth.
However, when the operating system is in use, System Restore generates restore points based on system
use, which can have a significant impact on OS-disk growth.
The function of Windows System Restore is the same as View Composer refresh.
As a best practice, you can disable Windows System Restore and avoid unnecessary growth in your linked
clones.
If you do not use refresh, evaluate whether it is best to leave System Restore active in your View
environment.
Procedure
1 In vSphere Client, select the parent virtual machine and select Open Console.
2 Log in to the Windows 7 or Windows 8 guest operating system as an administrator.
3 Click Start > Control Panel > System and Security > Administrative Tools.
4 Select Task Scheduler and click Open.
5 In the left pane, expand Task Scheduler Library, Microsoft, Windows.
6 Double-click SystemRestore and select SR.
7 In the Actions pane, click Disable.
Disable Windows Defender on Windows 7 and Windows 8 Virtual Machines
Microsoft Windows Defender can contribute to linked-clone OS disk growth and increase IOPS in linked
clones and full virtual machines. Disable Windows Defender if you install other anti-spyware software on
the virtual machine.
If Windows Defender is the only anti-spyware installed on the virtual machine, you might prefer to keep
Windows Defender active on the desktops in your environment.
