If it isn't broken, don't fix it.
Windows 10 is a good example of this.
There is nothing wrong with Windows 7, so if you have Windows 7, there are few reasons to move to Windows 10.
Now, I don't blame folks who don't want to deal with playing the update game with Microsoft, but there are other options out there aside from Windows 10. GNU/Linux Lubuntu is a good example of one. If you have a fairly good head on your shoulders (I'm not a geek either, so if I can do it, you probably can too), you ought to be able to modify Lubuntu to your liking, and you can even dual boot with Windows 7 and knock Windows 7 offline. That's what I did.
Alternatively, if you like Apple products (I'm not a big fan, although I did like OSX Leopard when it came out), you could switch to a Macintosh. They are more expensive, though, so they might not be in your price range.
