> (Optional) Provide Disposable Desktops
> For DVMs in a Pooled Desktops collection type, you have the option to make those DVMs disposable by making each DVM’s hard drive a non-persistent disk. If you intend for most of your users to have a Pooled Desktops collection type and you want the DVMs in that collection to be disposable, make the configuration change as part of your template.
> With disposable desktops, when a user makes any changes to a DVM, then logs off, Windows powers off that DVM. When that DVM is powered on the changes made by the user are gone due to non-persistent disk.
> A non-persistent disk adds greater security. If while searching the web users downloaded viruses, the user data associated with that virus would be immediately deleted after the user logs off, and that virus would not spread to future users of that DVM from the pool.
> Often users save cookies and passwords as they browse the web; this data would also be deleted. Lastly, any personal files that the users saves would be deleted, so that other users do not have access to this data.
> There's no need for users with disposable desktops to understand that their data isn't saved because users of a Kiosk expect their data to be deleted when they log off.
> To provide disposable desktops:

> 1. | Download PsShutdown to the DVM’s desktop. PsShutdown is part of Windows SysInternals (PsTools).

> 2. | Extract PsTools.zip to a PsTools folder on the DVM’s desktop. PsTools.zip includes many tools, but you only need one of them–PsShutdown.

> 3. | Assuming that psshutdown.exe is under C:\\Desktop\PsTools, add the following line to SessionLogout.cmd script under C:\Program Files\Pano Logic\Pano Desktop Additions\SCRIPTS:

> “C:\\Desktop\PsTools\psshutdown.exe” -k -f -t 2

> 1. | Copy psshutdown.exe from the temporary folder to is part of Windows SysInternals

> 2. | Configure DVM’s hard drive as a non-persistent disk:

> a. | From VirtualCenter, right‑click on the DVM and choose Edit Settings > Hard Disk.

> b. | Change to Non‑Persistent disk.

> 3. | Power off then power on the virtual machine. A reboot won’t do the trick. You must power‑cycle the DVM.

> 4. | (Recommended) To minimize the amount of time users need to wait for a DVM, when you create the Pooled Desktops collection type set Extra Powered Off to 0 and Extra Powered On to at least 3.
