Lol, me too - I was a Windows person since 1995 when my first IBM Aptiva came with a pre-release of Windows 95. Actually, I had used Windows 3.1 at a relatives house before that. All the way through last September when I converted to Scientific Linux 7.1 at work, and then a couple weeks later at home. Granted, I'm not an "average user" but I also converted my Mom, who is - and was on an old PC running XP still. She wasn't going to buy a new computer, but SL7 on there and it's like a new PC. Still does everything she wants but she asks me questions A LOT less often because Firefox and Flash update themselves and so facebook seems to work better than an old Opera and old flash on XP. Also she doesn't have to try and understand what the AV program notices mean (mostly because I haven't installed one yet as it's less necessary)...
It's also nice because she doesn't have to reboot very often, though XP was done with that with the removal of updates so . . . Win 7 still reboots every 2 weeks or so it seems with some update. That's actually the most common complaint about Windows 7 at work is the "constant" (actually overnight ,once a week or 2 weeks when there's a patch) reboots. Which the Linux workstations just don't do. They reboot for power outages, and "when one feels like it".
For an IT guy, the best thing about Linux is that it's a lot like how I felt with WIn95 - something new, and always learning something new. I realize that's not a benefit to most users, but once you know Windows (or any OS), it ends up being mostly the same.
The thing that really excites me (I'm just geeky I guess) is I bought crossover and I can run some Windows programs on Linux. Of course, now there's Ubuntu for Win 10 so you can go the other way...
Anyway, the nice thing about Linux is that it's still "dumb" enough to have an override to use the "old fashoned" setting where it just does what you tell it to and it won't second guess you, but by default it now has some of the nice "auto - make it work" stuff we've all expected from Windows. Microsoft has forgotten that having that override is really desired by the power users, and has gotten rid of it.
The issue with using Spybot AntiBeacon, which I checked out, is that any patch from MS can just re-set the registry settings (they've done it a couple times when someone changed their default browser for instance on Win 10), or ignore the registry setting, or decide to use different ones.
