Several years ago I got a Fujitsu laptop (Fujitsu Lifebook AH512 Laptop) as a present but I didn't use it much and finally abandoned. But, recently, I thought to start using it as I need a second laptop in addition to my primary one. It's an i3, 2GB RAM, 160 GB, and 32-bit laptop and running on Windows 7. I hope to repair its minor defects and install Windows 10. My confusions are, Is this brand still demanded and is it worth repair a 32-bit laptop? Can I install Windows 10 on this? I need to extend to RAM and is it possible
