For Windows To Go drives that are running Windows 8.1, there is no difference in Store behavior between a standard Windows installation and a Windows To Go installation. Store apps can roam between multiple PC’s on a Windows To Go drive.
For a Windows To Go drives that are running Windows 8, the Windows Store is disabled by default. In Windows 8, apps licensed through the store are linked to hardware for licensing. Since Windows To Go is designed to roam to different host PCs access to the store is disabled when running Windows 8. You can enable the store if your Windows 8-based Windows To Go workspaces won’t be roaming to multiple PC hosts.
Q) Why is my device's Windows to Go Store empty?
A) It is possible that you are on a Windows 8 image and using your WTG device on a different host machine. Please update your drive to Windows 8.1 if possible. If not, you should contact the device administrator and request that it is provisioned with a Windows 8.1 image.
Q) I have installed apps on my primary desktop computer (not running Windows to Go) using my Microsoft account. Will the apps show up in my WTG drive?
A) The apps will not appear on your WTG drive. However, if it is a purchased app, then you can simply log into your Microsoft account and re-download it onto your WTG drive without having to pay for it again.
