i’ve got one user who has refused to update their win7 system for a full decade–literally the entire lifecycle of win10. offered to set up a dual boot for her and she seemed to be receptive of that–even bought a nice big ssd drive for it, but she never used it and never upgraded. husband says that ssd is still in the damn box sitting on a shelf. i expect to hear from her when that now tired old hdd in her (i think) wolfdale-era win7 finally craps out.
