User Installs Every Version of Windows From 1.0 to 7, Sans Loathed "ME"

Iterative upgrade experiment reveals intriguing overlooked details about what is preserved and what isn't

An enterprising UK IT user who goes by "The Rasteri" on YouTube has completed an incredible "experiment" [video], in which he installed every major version of Windows, upgrading, in order of their release, inside a virtual machine.

He describes in the video, "It is hoped that this will shed light on how the Windows upgrade process has changed over the years."

For his testbed he used a machine running VMWare. He says he selected VMWare based on its snapshot and video recording capabilities. Also, importantly, VMWare offered full support for all legacy Windows operating systems.

I. Early Windows -- a Slow Evolution

To start, he installed MS-DOS 5.0 on the virtual machine, as most early versions of Windows required it as a starting point for installation. He describes, "Installation was surprisingly easy for an operating system of this age. It even partitioned and formatted the hard drive."

Win 7 Pro x64 SP1 OS X Snow Leopard 10.6.7

3) Can you do the same thing with Mac OS?

I don't know enough about Mac OS to be able to say, and I would not be the best person to do that experiment as I have never been a Mac user.

Windows 7 Ultimate x64

Thank you this is very interesting
Now I would be interested to see it done with computers instead of vmware to see the stages where hardware must be changed, and how easy/hard it would have been to backup and reinstall the early OS's
