I'd like to understand your answer a little better, in particular, why you 
have no issues with Windows licensing.

As background, I remember when (although I'm pretty sure I had already 
switched to LInux), Microsoft started the policy of making it difficult to 
upgrade a system without possibly buying a new Windows license.  I never did 
it (under that policy), but iir/uc, if you did certain upgrades to a system, 
your Windows would stop working, and you'd have to call them to get some kind 
of code or whatever, or, they might tell you that they consider that so much 
of an upgrade that they'd insist you buy a new copy of Windows.

As to those certain things, I don't recall that either, but could include 
things like disk, video card, processor and / or mother board upgrades.

So that is what I'm concerned about.

Maybe I should ask, how did you get Windows on the system you are discussing--
I mean, did you buy the machine with Windows on it, and then add Debian to it, 
setting it up so that Debian is the host system for the VM system, and somehow 
converted Windows to work in a VM?  

Or maybe you obtained a system without Windows, then bought a license and 
installed Windows in a VM?  (I'm not sure there is any difference between this 
scenario and the previous one as far as Windows is concerned.)

I guess in either case, have you made hardware upgrades that, perhaps in other 
circumstances, might have "triggered" the need for upgrade permission (or a 
new license) from Microsoft?

If so, did having Windows in a VM avoid that problem?

Oh, (on more careful reading) you're talking about a restore rather than a 
hardware upgrade--hmm, I don't remember (maybe I never knew) whether a similar 
Microsoft policy had to do with restores?

Or, am I totally confused???  (Well, I probably am, if not about this, lots of 
other things ;-)
