I agree with you on Defender, at least to my understanding it's only job is to check system files to make sure they are good, not meant to be antivirus
It's too bad that Microsoft didn't advertise this more.. This was the case in windows 7. Now in Windows 8, Defender has been upgraded to a full on antivirus suite. This is good for consumers that don't know to buy additional anti-virus software or don't want to be worried about it and have it built into the OS. You can't really knock it until you get a virus that it can't handle that another AV can.
But... but... with Windows 7 you could just hit the Windows key and start writing the name of a program. Exactly like in Windows 8. And you were able to pin programs to the start menu (where you had this neat arrows that allowed you to open recently opened files). I really don't get your post spaulagain, what's more efficient on Windows 8 than before?
So here you are both complaining that it does things the same.. and complaining that it doesn't do things the same.. in the same post... I have read a lot of posts on different sites and on this site also about people that make a lot of statements that are just not true. Things they are misinformed on because they most likely haven't used the OS and/or just read about it on some blog and then assumed it was fact. Not saying that's you, just making an observation. I feel that you need to give a product a try before making up your mind on something.
In Windows 7, I put all my most commonly used programs on the taskbar and I didn't bother pinning them in the start menu, no real reason to Since they were on the task bar... In windows 8 I have them pinned in both spots.. Why? Well for starters, you start off in the start menu (funny how you START at START instead of START at the desktop then go to START... so name makes sense now.. but that's more semantics than anything of real significance..).. Also my OCD can be appeased as I can put them all in columns and all organized by category and name instead of just a single list for everything.. Granted that is probably just me... I have to have organization of everything.. even my old iphone wouldn't have full app pages because each page had to be a unified theme or category... but I'm still a customer as much as you are..
With the typing to search.. It is more efficient on Windows 8.. Now you can search for everything on your computer. Literally. Files, Programs and Apps, Settings, and send those search queries into apps and pull up their search screens.. It also saves your most common searches and recent searches (if you don't disable this feature).. Want to search for a pie recipe? from the start menu type in "apple pie" and click on Internet explorer and it will open up a window in IE with the bing results for "apple pie".. or click on allrecipes.. or the google search app.. You couldn't do this before.. You had to open up your browser and search from there.. That may not seem as interesting since it's about the same number of clicks however with the integration of apps like I said, if you wanted to find something on The New York Times, or Wikipedia, before you had to open IE and Chrome or whatever and search for it and then click on the site.. Now you can just type "apple pie" and click on Wikipedia app and it launches the app with the results. I call that more efficient.
Recent document tab? Yes, this isn't there from the start menu.. However pinning to the desktop taskbar, just like in windows 7. If you right click on the icon in the taskbar the menu pops up and gives you recent items. Assuming the program supports that (which not all do, even in windows 7). Also most programs support an "open recent" anyway. I don't know what software you use so I can't really say whether that is available to you or not. But the point is, the feature itself isn't gone.
As for what is more efficient on windows 8 compared to windows 7.. There is a lot.. Whether you choose to acknowledge them or say "well I guess but windows 7 is still fine with me" or not, that's up to you. Windows 8 Is faster. All of the reports have shown windows 8 to boot faster and load most programs faster than windows 7. Windows 8 is touch optimized but does NOT require a touch screen to use. I do not have a touch screen and I am able to move around just fine. Have a long start menu? Roll your mouse wheel.. You've been doing it for years on webpages so it's not a foreign gesture for scrolling through stuff. For those of you that prefer keyboard shortcuts and don't like using the mouse since your hands are always on the home keys, use your keyboard arrows and the enter key..
For closing apps, you are used to going to the top corner and clicking the X button right? So instead of clicking on the X, click at the top (which assuming the program was in full screen or max mode, would be at the top of the screen anyway) and just drag down. Want to go back a page in an app. The back button is on the top left of the page. In about the same spot a back button would be on any browser. Or, just like in any browser... Many apps also support the backspace to go back a page.. Assuming you aren't in a textbox typing something.
