More than 6 months on from my original post and I thought I would give an update, point-by-point:

1. The first thing I noticed that the Win 10 windows are far uglier, they have lost the beautiful rounded edges and transparent Aero look. 
  The Start menu and Action centre have the Aero look (there's a 'transparent' setting for this, so you can turn it on and off), and now the windows have an optional 'accent colour' picked from the background (which you can automatically change from time-to-time) so this is a big improvement.

2. The Win 10 task-bar is less functional, you can't pin programs to the LHS, and the alphabetical 'all program' list is too long (on Win 7 I have everything grouped together in thematic folders). 
  This is now better, if not perfect, I've managed to customise it more to my taste. I still prefer the Win 7 one!

3. The hideous dull tiles .. 
  No change.

4. Win 7 is much more stable... 
  Win 10 is getting better, but there are still problems, for instance a friend has recently lost use of her start menu, and I've spent hours trying all sorts of fixes I found on the Internet to get it back, but without any success. 
I haven't been able to use many of the new Apps at all, for instance if I try to open a picture with Photos it immediately crashes.

5. With Win 10 you have no control over Windows Updates any more... 
6. There is no information about what the Win 10 Updates do any more. 
  MS has bowed to pressure and now you can get Info about the updates and also uninstall them (for a while!).

7. Microsoft can now access your private details with Win 10... 
8. In Windows 10 Microsoft will use your bandwidth... 
  You now have a lot of control over what info you send, and can easily turn off '8.' (although you need to be computer-savvy enough to find all the settings! 

) I also saw an article that claimed that a lot of the computer press were scare-mongering and that MS only took a lot of this info to make programs like Cortana work properly. Also that they were no worse than Facebook, or Google, say.

9. In Windows 10 Microsoft have added the possibility to put adverts directly onto your OS. 
  So far I've only see Ads for things from their Store on the Store tile, which I can turn off. I suspect they might be putting Adverts on the Lock Screen, but I've turned this off, too.

10. Windows Media Centre is removed (not such a big deal, but I use it to watch TV). 
  With a bit of searching I found a much better solution using the open-source VLC and the program codes to use my Internet box (which has hundreds of TV channels).  
So, all-in-all Windows 10 is much better than last year, and all my programs work much as they did with Windows 7.
