I have two Win 7 laptops that I've upgraded to Win 10 - I've kept an older Toshiba on Win 7.
This one is a Toshiba C660-28R which has an Intel Celeron dual core B800 1.5GHz CPU which works well with Win 10.
The other one is a Toshiba C660-1GD which has an AMD dual core 1.3GHz CPU which seems a little bit slower at times, but from your specs, I don't think you will have any problems if you can get the free upgrade.
All three machines have 8GB RAM installed.
However, Toshiba told me that neither of the two C660s were compatible for Win 10 - not sure if they were hoping I'd buy a new machine
