I have a Win7 desktop and laptop.
I use the desktop for ‘real’ computing.
I use the laptop for perusing the net while watching TV.
Ironically, the laptop has an i-7 processor and the desktop has an i-5 processor. The desktop has more production power than the laptop.
I have started getting ‘your browser is out of date’ messages on some websites. I dread the next level of replacement (Win 10 or later). I had to jerry-rig some of the old XP programs to run on Win7. I lost several others — most of which do not have comparable replacements.
The problem with trying to update is that is creates new problems while, maybe, fixing old problems. I have had conflicts with Win7 updates, Firefox, Palemoon, Java, Adobe Flash, and several others. Fix one problem, and it breaks something else. I stopped most of my updating early last year — because my programs were working together then.
