I think that your computer may be too old to upgrade to Windows 10. You can buy a refurbished one for under $200.00 (s/h fees may apply). It all depends on what you want to use your computer for.Hi, I have an old desktop computer that I don't use very often, it is running Windows Vista. I realise that support has ended for this OS. Is there any way of upgrading to a later operating system without spending too much?
