Yesterday I tried out the Windows 8 To Go feature which allows you to run Windows 8 form a USB drive or USB stick. If you’re looking for a step by step guide, I suggest you look at the Microsoft TechNet Wiki here.
Having booted Windows 8 To Go on nearly every desktop and notebook device I have at home I wondered whether this would work as smoothly on a Thin Client. And yes it does. Below you see a picture of Windows 8 32 Bit booted from USB on a HP Thin Client T5740e that normally runs Windows Embedded Standard 7.
