Back atcha!! 
Ah, I see. I do something similarly on the Mac side, though I don’t create subfolders for vendors/classes like you’re doing there. I think SB is right to leave the file structure to the vendor, and to provide organizational features to you with the Plug-In Manager and your customer sets of plugin folders in Cubendo itself rather than mucking about at the file-system level. But I see what you’re doing there 
It’s hard to do. I’ve create a new primary workstation with my recently purchased Mac Studio rig and I’m doing the same thing. I’ve been really good about not loading the tons of software I’ve accumulated over the years and am trying to stay mostly within the SB product line (with synths anyway) thought that’s tough to do. I still have my MBP fully operational on what is now the second workstation behind me. I got a new RME interface for my primary and moved one of my UAD x8’s to the secondary, but still have an x8 on the primary for both DSP and UAD-specific equipment like my Sphere DLX, etc. RME is pretty amazing 
As others have said, I think it’s worth your while to get a fully features backup application that allows you to boot into the restore environment, and not have to fully rebuild and re-install to get to the point you can then access the backups. Not sure what the state of that art is on Windows, but I’m sure other folks can help you out there 
I’m glad you’re back up and running though!
