Okay, it has been a few weeks. Windows 10....not ringing my bells. I have received calls from angry customers claiming that Windows 10 "downloaded itself" even though Windows Update was turned off. Worse yet, are those who decided to try the upgrade, only to have it fail during the upgrade process. These things can be fixed, but not by average computer users. I am hearing bad things about Microsoft digitally signed drivers which replace manufacturer drivers that work with bad ones that don't work. Again, fixable, but not easily. And, of course, there are the intrusive "features" which remain.
I do not like this operating system. I liked it when I was testing the Technical Preview, but that was understandably buggy and unfinished. Turns out it was basically what we got for the release of Windows 10. The flat graphics and dark theme it starts with is visually boring. It can be changed, but without the nice shadowing of icons and clear sections defined by lines, everything is flat.
Edge...it is crippled, compared to IE 11. It does some things much faster, and other things it does not do at all anymore. Importing bookmarks is buggy and unreliable. Sharepoint is hosed in Edge. Things that you want to see for adjusting the browser are somewhat hard to find.
Windows 10 does not play DVDs natively. Even Windows XP could do that.
Cortana...she is very very effective, if you turn her on. But if you do, you have to turn on a bunch of other stuff you might not want to turn on. The strategy seems to be the same as cable companies used to get you to buy HBO. Go for the Cortana Package, and you also have to give up your privacy on many other levels. Cortana seems like she was designed for phones (like the new Surface Phones coming out). I do not see her usefulness on a desktop PC unless you do not already use Dragon for dictation. I will never imagine an office where people are sitting at their desks talking to their PC.
For what it is, it is okay. But I see no reason to even slightly think about leaving Linux Mint for Windows.
