I use win 10 and are happy with that, sometimes i need to switch over to IE instead of EDGE if i should have some old map's from the county or even some files in here at the forum, but else EDGE do the job.
I have win 7 on the old machine but that one is basically a dustcollector now, and i had a big job to keep MS's fingers away from it when they want everyone to switch over to win 10
The "Cloud" is just a fancy word for trying to hide " i want more of your bucks " in my head, and the same thing with this socalled service fee, we buy a program, get an old version/ built of it and need to pay extra for get the last buildt of it, truly i dont see that as a service.
Of course the company's should make Money, i only just dont like if i dont get an option, and that is also the mainreason for why any Appleproduct is "forbidden" in my household, i have always been, and still are anti-Apple
So it's just a matter of time before all programs is sold that way, they should all survive and give profit to stockholders, so from that point of view it's understandable, but i dont need to like it.
I have Adobe XI, but stop using it after i got TurboPDF, and i also used CutePDF that is free before that again, and at least back then there was no commercial on it, have no ide'a how it is today.
So you could try look for that, there is also one another that Jeff talk about, 3 digits like 936PDF or similar to that.
One of this should be able for you to use and be able to read pdf's, but if you want edit/ write a pdf i assume you need to buy one.
But you can write in TC and save as pdf if it's only simple needs.
