Finding a Secure Workspace

Recently, when working at a client sites, I’ve taken to occasionally using Windows to Go. This is Microsoft’s little-used secure workspace feature for Windows. It allows you to boot into a secure workspace located entirely on a USB key. This enables you to use Windows without relying on the operating system, applications, or storage on the host device. It creates a secure workspace on any machine that can boot from a USB drive without trusting the host machine. I have even devised a way to use a Virtual Machine (VM) in this workspace. Because the workspace doesn’t rely on the host operating system, the workspace on the USB drive isn’t at risk of compromise from a host machine and the VM protects the USB workspace. This saves me from constant use of my ‘Safe Mode on steroids’ or reinstalling Windows from a drive image on a client’s machine. However, it is too slow and requires too much effort to maintain. A similar live Linux USB seems to offer faster performance and it is easier to maintain the VM.
