I have W10 Pro 64bit
I purchased a 2nd hand PC with it freshly "installed" (seller had done a clean install of W7 Pro, and did an immediate update).
I created an image, and restored that into another hard drive, and I rolled that 2nd drive back to W7 Pro.
Then put back the first W10 Pro drive.
I purchased the PC, not because I love W10, but because MS insist on throwing away old tried & true approaches, with every new version of windows. (EG settings are all over the place, and some are gone). So I figure I better get used to it because friends and neighbors often get free help from me.
I am pretty sure I found out how to prevent auto updates. Allowing me to control when they will occur.
Do you wish me (and my 7 decade old brain) to dig around, and recall how I did it ?
