Help with System Environment Variables

Hi all:

I apologize if this is not the right area for this question but it didn't seem to fit anywhere else.

I am having a problem understanding system environment variables and hope someone can educate me a little.

Specifically, I am trying to set up Virtual box on a Vista Ultimate host so that limited users accounts can access the virtual machines.

I found the following information out on the web while trying to research the issue:

" By default all VM machine and disk data is stored in the .VirtualBox directory located in your home directory, C:\Users\<username>\ ".

This,I believe, limits the use of the VM to the user who creates it. If this is true, then I think the following sys environment variable would allow all users access the the vm's:

HOME = C:\Users\Public\<folder for organization purposes>\

I did a test run of setting up a VM and followed the creation process until it got to the point where it had finished configuring with the following location given for creating the file:

C:\Users\my_name\.Virtualbox\HardDisks\test.vdi

I found a similiar post on a Virtual Box forum but the response given was that the sys environment variable should be:

" HOME = C:\HOME"

I think that is wrong since there isn't a "HOME" directory in Vista.

Can anyone tell me if my thinking is correct, or, if not, where I am wrong?

thanx in advance...
