Hang onto Windows 8 as long as you can. Win 10 acts like a virus to older computers. I also think Microsoft uploads updates to slow older computer down. 10 will corrupt older media formats like flash drives and sd cards. None of my video camera work with 10. I cant use my new Go-Pro because of "Corrupted Files". If you plan to go the Linux/Ubuntu path order the latest install disk from Amazon. You can run Linux off the disk without installing it like I'm doing now. You can install it along side window and dual boot it. Instructions on Youtube. Linux Mint comes with tons of default programs that run like microsoft programs. Sound quality sucks. Linux wont run sound or graphic card. Most windows software will work with Linux. Most downloads are free as everything is open source. Something to think about before you make the sacrifice to Windows 10.
