want to test ubuntuGnome 14.4 - a question for iso files

[Hadi]

Hello guys

I'm about to test Ubuntu gnome specially in terms of accessibility.

My  OS which  runs the virtualization is a windows7. are there any 
programs  in windows that could work  similar to TestDrive?
I'm restrictive on bandwidth, and i'm looking to avoid redownloading iso 
files as they get uploaded.

Thanks for any help.
P.S i know this list is for ubuntu gnome and for linux in general, but 
i'm asking since i couldn't find anything in  google.

Cheers
Hadi
