Microsoft has just launched a beta program at connect for Windows Thin Pc. Its intention is to be able to install a light weight operating system to old machines and elevate VDI and terminal services. I just had to install it and test it out. And guess what, it looks great. See screen shoots below.
Cannot add or remove windows features. This is disabled.
Uses 2,67 GB of space after it is installed. (that’s small)
