I can fully appreciate your reluctance to re-install Windows. I faced the same decision, but decided to bite the bullet. I knew that my Windows environment would eventually need to be rebuilt anyway, for one reason or another -- and that was before MS began to nudge everybody towards Win10.
By investing the time to rebuild my Windows environment as a VM, I will never, ever, have to do it again. Ever. I now have the VM backed up on a USB drive. If my workstation were to catch on fire right now, I could replace it with any make or model of PC, and have my Windows environment back without having to re-install apps or drivers. Windows would never know the hardware changed. That measure of security alone was worth the investment of time to virtualize.
I'm not familiar with rollbackRX, nor the way it functions, but I can see no reason why it wouldn't work in a VM. It would still be running in Windows. The VM appears to be physical hardware to the Windows OS. The only difference is that you have absolute control over what Windows can see or access.
[[Unless I have missed something somewhere, the host OS must have access to the network if any of the virtual machines need access to the network. The host OS owns the hardware]]
Ok that’s what I thought-

I’ve done something similar- I have a physical hard-drive duplicator (about $60) that does a fantastic (but slow) job of a 1 to 1 duplication-
I got my main drive (C drive) to where I want it- all the updates, tweaks, UI changes patches, drivers etc etc etc done, all software updated (things like photoshop, OnOne photo suite etc) and I duplicated the disk onto another hard-drive- (I’ll just miss any recent updates from here on out and have to redo them if I plop in the new backup hard-drive but the bulk of updates are all done)
Here’s what I’d like to do if possible? Download an Linux .iso, burn it to DVD- run it- make the tweaks I’d like to make, and somehow reburn it to a new disk once I get it the way I like it (I’ll want to add programs ot Thunderbird and Mozilla browser like Adblock, Ghostery, etc- Would You know if this is possible? Ho would changed user settings be saved? On the Windows ‘C’ drive?
