AFAIK Microsoft purges or resets the activation database after one year for any keys that have not reached # of activations that are deemed 'suspicious' or 'excessive'.As I mentioned in OP, is you change the chipset, technically it does not work. You have to call to activate.
I've only bought vista when it was current. And I lived through it with no problems even when Win8 came around. Now I'm on 7 and no reason to move up.
I've seen a couple things about running W10 on a Lenovo T420 and it being fast, but I can't speak for something with 2GB and there is the other problem of older laptops - you'll be stuck hunting down your own drivers if they aren't included in W10 and the manufacturer isn't "supporting" the upgrade on that model. The latter is the main reason I'm sticking with W7 on my laptop.Does win 10 by chance run better/faster than 7 on a slower laptop (HP Pavilion G7)? I believe it's only got 2GB RAM.
I've paid for two oem copies of XP, and MS gave me Vista. That was the last Windows I used.

I have T410 with 4gb ram, it got automatic update, runs just fine without any issues. It's not any faster than 7 though, in my experience speed wise they are same.
One thing I noticed on my desktop is that 10 was phenomenal with drivers, I didn't have to install a single driver for any of the peripherals or add on cards, everything was automatically installed, it was unbelievable.
Man... no wonder you like Linux so much. If Vista was the last version of Windows I ever used, I would have bad memories of it as well!
I'm surprised that you haven't been issued a work computer that uses Windows 7 at some point by now.
OK, now I am pissed, I do not expect to see commercials after I shell out big bucks... I am reaching the breaking point.
