Windows To Go workspaces is a new feature in the Windows 8 Enterprise version that enables users to install a full-version of the operating system in a USB drive and have fully featured Windows environment (OS, apps and documents) anywhere the user goes.
This is a feature intended only for businesses who often work with custom-build images and with specific settings and security configurations. And in any way Microsoft is pushing Win To Go as a replacement for the everyday desktop or mobile device — It’s just an alternate work environment.
Instruction

Open the Run command with the + R keyboard shortcut, type gpedit.msc and click OK , to open the Local Group Policy Editor .
Navigate through the Computer Configuration > Administrative Templates > Windows Components > Store .

You’ll see three setting options, select and double-click the “Allow Store to install apps on Windows To Go workspaces” .
Then select Enabled . Click Apply and OK to complete.

That’s all there is to it. Enjoy!
It’s still possible that in the near future the software giant may push this feature to at least Windows 8 Pro, but for now it will only be part of the Enterprise version of the operating system.
