I know on my 8.7 machine I had to find a small program to make it operate as windows 7 does, same start menu as 7, and same control panel, close enough to make you think you are running a 7 machine, without it, this machine would probably still be sitting in the box.
Just did the 10 upgrade on my DELL XFR D630 (Intel Core two DUO with 4gb ram ) running WIN7 x64 Ultimate.

It not only upgraded without a hitch but the desktop still looks a little like WIN7.
Very little change in the desktop menu at all. The "Start" menu looks a tad different with the selectable tablet menu, but not much changed.
I have an SSD in the computer and it ran pretty fast with 7.
The boot up/shutdown and interface is noticeably faster with 10.
It's not my reg'lr computer that I use for banking and and all other forums though...... but it seems to work just fine.
Let me also add that I set up a computer for one of my wifes friends. A widow in her late 70's bought a new laptop with WIN 8 on it.
She had been using XP for several years on a desktop and wanted something new but couldn't figure out how to use 8 I set up her "8" computer with an application that made 8 "look" like 7 and she was able to use it.
She brought the laptop over again and had some questions about the 10 upgrade that was bugging her to do so I did it on her computer. I removed the after market "7-lookalike" application and just accepted the 10 (non-tablet) interface and she's having no problems making it work.
If a fairly NON-computer literate grandmother can use 10, I think anyone can.
Just make sure you look at one of the tutorials that explain what privacy settings you should or should NOT accept when asked in the upgrade. (I left just about ALL the settings to "send to MS" OFF)
Cheers,
