"Windows 7 diehards"???
You WHAT? You make people like me who want their OS to actually work for more than 3 days at a stretch sound like Alf Fucking Garnett.
I've got a Win10 machine on my desk at the moment. It was a Win7 machine. Customer did the upgrade. Computer is fucked. Processor at 100% all the time, half a dozen popup programs at the start crashing straight away.
I have another one on the desk too. Customer did the upgrade. Computer is fucked. Windows Live Mail doesn't work, random internet disconnects from the wireless card, start menu sometimes works and sometimes doesn't. Programs load, or don't. PS2 keyboard and mouse work, but only if you switch the machine off and on a few times. That one I have just restored to Win7 factory settings.
I just sent another one off today. Customer did the upgrade. Computer is fucked. Won't print to 3-year old HP wireless printer, won't run Chrome or Firefox, long (3-4 minute) delays between clicking on a desktop icon and it activating. Restored to Win7, oh looky, it works fine now.
Fixed another one on Saturday. Customer did the upgrade. Computer is fucked.
Do you get the picture now? Windows 10 is NOT READY and it was wrong to upgrade everyone's computer and force them on to it. It was stupid. No, it was cretinous, arrogant, and monumentally stupid. I have been rolling out GWX Control Panel as fast as I can to my poor customers to spare them any more misery.
Diehard? Don't make me come after you in a white vest with a machine gun.
