Ok so I've tried every fix I can find/think of and Windows 10 still will not download on my husbands laptop, mine however upgrade perfectly on the first try.
He has Windows 7 Home Premium, Service Pack1
Processor is AMD E-350 Processor 1.60 GHz
Installed memory (RAM): 4.00 GB (3.60 GB usable)
System type: 64-bit Operating System
And it shows Windows is activated
computer is Lenovo b575

The Windows 10 app to do the registration for Windows 10 never came up on his computer, KB2952664 update will install but then it is shown to not be on the computer even though I can see it. When I try to do the update with 54% of the memory available at the point of install, it goes through everything all the way to what was the last screen on my update where it shows, Windows 10 installing, Your computer may reboot several times, Your computer will reboot in a moment, please wait, it sets on that screen for an hour + and then goes back to the Windows 7 desktop with the grey box showing Something happened in the top part and Windows 10 installation failed in the inside.
I can't figure out what is going wrong with this update but it's driving me nuts and I don't like to not be able to figure something out.
Any advice?? Ideas???
