I basically don't use any of the apps. When I logon, I click the Desktop tile, and that takes me to the desktop (that is similar to other versions of Windows).
For browsing. After getting to the desktop and opening Internet Explorer..
Go to Tools - Internet Options - Programs Tab - Make sure the box is unchecked for "Open Internet Explorer Tiles on the desktop.
This will make any link you click in email, etc open on the regular desktop, not the app.
If you want to have access to any of the programs...while on the App screen, right click the tile and select "Pin to Taskbar". This will place an icon on the bottom of your desktop (or top/side depending on how you have it configured). You can also choose to pin it to the start screen as a tile.
To see all of your programs...while on the app screen...right click down towards the right corner, and will pop up, "See all programs." From here you can then choose what you want to pin to either the start screen or your desktop.
I know I am not taking advantage of what Windows 8 was intended, but it was too frustrating having things open as an app. No menus, no real navigation.
There is a good Help section, that should be visible when you click the See All Programs. I pinned that to my taskbar for easy reference.
I also pinned the Windows Defender to my taskbar, so I can update the definitions & run scans manually if I wanted to.
I found out the hard way that Norton does not play will with Windows 8. I used the free version from Comcast for years on my old (XP) but on this one, even though they say it is compatible, was just horrible. Hang time was literally 10 minutes sometimes, scans were running all the time because Norton couldn't determine when the system was idle.
I hadn't done my research and didn't realize that Windows 8 comes with Defender, which is now a full anti-virus, anti-malware (the old Defender was just anti-malware). I was nearly in tears thinking I spent all this money and my 10 year old XP was 100% better!. Once I uninstalled Norton and had Defender going, it was like night and day.
One think I really like on Windows 8 is the quick startup. From the time I push my on button to time I'm opening a program on desktop is less than 1 minute.
