This is a good guide to upgrading for free. It includes important first steps, like ensuring your files are backed up before starting.
My computer was bought in France about 10 years ago. It worked well until Windows informed me that I could not upgrade to Windows 10. I asked Dell Support if they could provide a hardware update and they were stupid and said I had a software problem. No, I have a hardware problem and I am contacting the manufacturer of my product. Maybe I should go home to Texas because Dell France does not understand even French.
