I still mourn the loss of my Win 7.
I needed to buy a laptop a month ago because my wife appropriated my c.2010 Fujitsu Lifebook that has Win7Pro.
I despaired -- everything I looked at was Windows 10.
And then I found a nearly-new identical Lifebook (c.2011) with Win7 Pro for about $200 on eBay. Amazing.
There will be a market for Win7 for a LONG LONG time. If you really want it back, there may be a way to accomplish it...
