Put Linux on them. There are many versions from those friendly to windows users (Linuxmint) to the very bleeding edge. I am currently running it on a circa 2006 Dell laptop and a mid 2006 MacBook. Hmm - the 2000 one may be getting long in the tooth.i been doing a lot of clean up. i have 3 old computers running xp. they are circa 2000 to 2008. is there any good reason to keep them or should i just recycle them? i tried loading win 10 into a couple of them and they won't take it .
So keep or recycle?
