Originally when Windows 10 was first released as a free upgrade, Microsoft’s end of support was listed by the year 2025, but this has all changed with each new major upgrade.
Some users who took advantage of the free upgrade back in July of 2015 (Version 1507) may now find that their computer is no longer supported and are stuck with either the original release or subsequent versions of Windows 10 (released about every 6 to 9 months) but can no longer upgrade to the latest version as their hardware is no longer supported.
You can check this list to determine if your computer is compatible with Windows 10. Please note that this forum article only covers brand-name computers such as HP, Dell, Etc. and those of you who built your own computer will need to contact or search their motherboard manufacturer’s website or find out the hard way.
