After trying out win 10 so far I have the following observations/gripes:
1. Start -> Run can't be run from keyboard, Instead if I press Start I have to enter whatever is the name of the application and press enter. While it's a nice approach in helping create an user-friendly product I find it just slightly annoying in that I can't run a command directly, for example, what if I want to start an app that's on c:\mydrive\myapp.exe ?
I can get around this by right clicking on the Start button and selecting "run" but I miss being able to start an app by just the keyboard and gets a little time consuming when having to switch gears to a mouse.
2. The new browser, Edge, does NOT automatically import favorites from IE. I thought it would do that when I selected Edge as my default browser and you would think that it would go ahead and import all the bookmarks from IE by default. It's not a big issue but just slightly annoying when I started Edge only to wonder where are my favorites.
3. The shut down menu is now much easier to access, just press Start and go to Power like so:
Much better than Win 8 which required some special right swiping motion and hoping you got the shut down menu.
4. The Start programs menu automatically alphabetizes the programs, which is a good idea in theory but at least for me sometimes it's not obvious where your app is. For example, I was wanting to start Word and you would think it's under "W" for word right? Well, I go to W and nothing is there:
But instead Word is under "M" for microsoft like so:
5. The notifications area is better in that it isn't so intrusive. I had issues when playing full-screen videogames and I'd get a popup from an app. Now with the new notifications section I don't get intrusive popups and it even leaves the notifications waiting for you and you can click on it later.
So far I like it just from the fact I don't have to deal with Windows 8 anymore and downgrading to Windows 7 isn't an option anymore. If it were up to me I'd rather keep Windows 7, it was stable and had a good interface. But oh well, Windows 10 is a better option.
