As netbook doesn’t accompanies with optical drive, so to install new software for it is a hectic job and thus thumb drive is the best option. Microsoft is also told to offer a version of windows which is downloadable and allows the users to save the US on any of their USB flash drive.

If this is done than, the released USB drive for the windows 7, would be first ever OS 7 in that format.  Off course, it would cost Microsoft a lot as it needs a 10 GB of space and such flash drive would increase the cost than a DVD.
