I have a couple of W7 discs around here and may revert back if 11 is foisted on me.
Either that or go all Linux and suffer a while to get equivalent stuff to work or fork out and go (shudder) Mac.
I had an Apple laptop once I got used at a good price, had it for a month. Sold it for a little more than paid. I never got Mac love.
My dad has the W7 OEM disk Home Premium.
