"The apps Ed - I don't do apps."
Yes you do - app is short for "application" i.e. if you've used internet explorer or Micrsoft word, you've used an app.
If you mean the "metro" apps, try "snapping" one like skype or the messenger "app" to the side of your screen by:
1. Opening the app
2. moving your mouse to the very top of the screen, until it turns into a hand
3. Clicking and holding, and then dragging it to the left third of your PC. Drop it there.
4. Press the Windows button and select desktop
I've found this kind of thing neat and useful. A bit like "snapping" left and right in the desktop mode (use Windows Key + Left or Right Arrow Key)
"And the screen when you go into things like ebay. It's so different and I don't like it and don't know how to change it."
When you go to the website, or when you open the eBay "App"?
If you'd like all links to open in a certain browser, set it as your default.
If you're using IE, and you'd like it to always open in Desktop mode, do this:
1. press Windows Key
2. type "opening links"
3. Select setting from the right.
4. Click "change how you open links"
The first section says "Choose how you open links" and from here you can set it to "always in internet explorer on the desktop"
"If they must change things why don't they at least tell you how to use them. I suppose it's just that I don't really understand technology."
When you started up using Windows 8 there's a 3 minute video which explains the basics. It's just clicking mostly :)
There's a little learning curve if you're not using a touch screen though!
Hope this is useful for you.
