Linux already has OS installation with a USB flash drive and it seems that Microsoft will make Windows 8 can do the same way. A copy of the early Windows 8 leaked earlier this week, giving a glimpse of a feature called “Portable Workspace Creator.”
This feature is described as:
“Portable Workspace is a feature of Windows that allows you to run Windows from USB storage devices.”
Those who want to use the Portable Workspace will need a USB stick with a capacity of 16 GB minimum.
It also displays terms have access the installation files of Windows 7 Enterprise Edition, so this could be a feature that is created for the business of it and not just for personal user. Perhaps Microsoft did restrictions somehow to prevent it from piracy.
Microsoft has not yet been officially informed about this new feature at all, but hopefully it will soon ensure features Portable Workspace, as well as other features such as History, Vault, soon.
