First to clear my credentials. I am CompTia A+ certified; DCSE certified; PC Specialist; & 1 more I forget. All those costly degrees & certs are tucked away in a drawer in my office.
So to my review.
I did the as this year free upgrade from W7 to W10. I was pleased. Within seconds I was able to navigate around.
1) Perhaps it is just me, but the learning curve was small. However my wife who is an average PC user was also able to get around W10 within seconds of logging in.
2) The Start menu is the best of all OS's that Microsoft has devoloped, except W8, W8 could be considered a sin . It was very easy to figure out how to remove tiles and pin tiles that I wanted.
3) I also very much like the ease of the file structure, it is logical.
4) It has a notable faster response than previous versions of Windows, which is of course desirable.
5) A much cleaner uncluttered feel & look
But I have a few picks.
1) Boot time. I think this boot time may be longer than Windows ME was. Every time I boot this laptop I am surprised at how long it takes to boot. But at least it is in your view long. W7 got to the desktop quick, but it was still loading the drivers etc.
2) When connected to the Internet W10 itself is adware, for MS products, nevertheless it's adware. I own a disc copy of Office 2010, but when connected to the Internet W10 tells me to "upgrade" to the cloud version, it's better. No it's not.
3) This one I am sure has a solution. In all previous OS's users had their personal folders on the Start menu. I have yet to find that option. Yes we have the "Explorer" folder that takes us there, but that requires 2 extra clicks. A long day on the computer, do the math. But it is not the biggest lost.
4) If you have more than 1 user profile upon reboot instead of taking you to a user option menu it logs in to the last user. I don't like that. My wife uses the laptop far more than I do, but when I do use it I hate the dire warning at shut off of other users being logged in.
Overall I think W10 may, may be the best OS MS has devoloped, but....I do not believe it will remain free. After 1st year I truly believe it will be subscription based. Perhaps it will be required if you want any security updates. MS has never given anything away or done what the majority wanted, without demanding something in return.
