Microsoft seems to have a habit of dropping support for older stuff.

I took the free win10 upgrade on my 9yr old computer which the "Upgrade assistant" said was compatible with Win 10. Then the 1st major update of win10 comes along, and suddenly the RAID array attached to my motherboard was no longer supported... Install update... windows fails to boot... cant even roll back... Eventually bit the bullet and upgraded the hardware... (which had an added benefit that I now spend FAR LESS time waiting for lightroom... )
