I am just going to have to close my eyes and hit the button when its time.
. I am not super good with computers, other than the basics and using them for a long time. Can't say I ever had any issues updating to a new system, although that usually happened because I needed a new computer. I have 8 on a newish Asus netbook and I have 7 on my main computer which is a desktop. I know how to back up my files including calibre library to the cloud, but that would be the extend of my skills.
Eventually I have always gotten used to any new versions, although 8 did drive me insane until I set the thingies to desktop and go the start thingy back. I don't like those tile thingies, can't even figure out how to personalize that stuff so I never go there on my netbook. It boots to the desktop. How I did that, I don't remember.
I have a feeling I'll be ok. No going back in any case as I have no clue how do do "image" or what that is or how to even use such a thing.
Like I said, I am pretty easy going on this stuff and haven't had really any issues with any windows versions yet. I never used Vista so can't speak to that one. Went from xp to 7.
I will do the update first on the W8 netbook in any case. Whenever it gets here. I signed up on both machines as I did get the logo thingy in the task bar on both.
