Not wanting to appear condescending, but, I have had very little problem adapting to 10 and I am by no means a computer tech guy whatsoever. I don't understand the logic behind knowing that in a very short time your OS is going to bite the dust. Why go to the trouble of upping to 10 and then immediately rolling back to 7, 8, Vista, etc....., when we all know that all windows versions beefore 10, according to microsoft, are dead in the water whether it's 6 months or 2 years from now?
if your computer meets the spec requirements and you know you have all your drivers ready, making the jump is probably going to be pretty painless. I learned on this forum how to disable the auto-downloads and other tweaks and I truthfully tell you that my computers have never run better! Even my poor old worn Acer dual core is running better than the day I bought it!
I don't advocate the features mentioned about privacy issues but I believe in due time the improvements in 10 will warrant a mandatory jump to whatever they decide to call the next jump to a NEW, IMPROVED OS.
At some point, you will HAVE to make a change. Whether it's jumping to 10 or Linux or a squeaky clean new Apple.
I would rather stay with an OS that is rooted to what I have used since 1996 than jump to Apple and have to learn a whole new workflow!
