Do you want to try out Windows 10 without committing to it on your home PC just yet?
I have a 5 1/2 year old PC for sale that is running Windows 10
Pentium Dual Core @ 2.2Ghz
2 GB RAM
160 GB Hard Drive
DVD burner
64 bit OS
integrated graphics
Completely reformatted and upgraded to Windows 10
Just the tower, no Keyboard mouse or monitor, though that can be negotiated.
