Registry hack to set the desktop icon size to small - Win7 64bit

I am trying to find the registry key that will change the desktop icon size to small.

This is mainly for new users, or for the default user. I have workstations that have several people sharing them and need this for everyone.

I have looked in these locations:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Bags\1\Desktop\IconSize
And
HKey_CURRENT_USER\Control Panel\Desktop\WindowMetrics\Shell Icon Size

I played with both these settings for myself, and the desktop icons do not change.

If I reboot, the first key value goes back to 32, and the second key stays at 96.
But my icons never change in size.

I am looking for any way to do this in the registry.

I could try copying the ntuser.dat but fear I will still have issues with paths, and other defaults that will cause the same problem I had originally.

Click on an open area of the desktop, then hold down the Ctrl key and roll the scroll wheel on the mouse. The Icons will get bigger or smaller depending on which way you scroll the mouse wheel. No Reg hack needed.

Found this here: group policy - Server 2008 GPO To Use Small Taskbar Icons - Server Fault

The key that is changed is as follows:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\TaskbarSmallIcons
Setting this to a value of 0x1 will force the taskbar icons to be small.
You can set this value via a GPO by navigating to the Preferences for Registry (Policy root\User Configuration\Preferences\Windows Settings\Registry) and creating a new value.

Thank you. I will try that, Edwar, I know how to do it manually, I need a way to do this for over 100 workstations, and automatically whenever a new user logs in.

Thank you.
