(This composed on my trusty 2002 T42 15" 4:3 running XP exclusively) Which is nonsense. Just because MSFT no longer supports WIN81 is no reason to ban an OS in a non-MSFT product. A legal disclaimer would have worked just as well. The only company I am aware of that is still happily supporting XP on a day to day basis is SYNC.COM, a friendly Canadian firm that competes with DROPBOX. DROPBOX threw XP under the bus a decade ago. Amazingly, the Sync people don't seem to be aware that MSFT frowns on companies that ignore their diktats. If I did not know better -- and I really don't -- I would say that powerful forces want XP dead and buried. The brilliant coder behind MYPAL was given a "legal warning" by the Palemoon people even though they themselves were no longer updating their own product. What's up with that? That was a great mod! To do my taxes, I have another machine, a 2009 Lenovo G550 that I do not like very much, compared to the T42. On boot up, you now get a choice of 5 OS's to choose from: the factory-original XP, Win7, Win81, Win10, and --as of this week -- Win11. You have to wonder how much business TT will lose when they ultimately force people to jump to Win11, which in many cases means buying a brand new machine? (This is not the tech forum but it is indeed possible to install Win11 on a 13 year old laptop in MBR/BIOS mode, no UEFI, no TPM. Check out the free PhoenixliteOS Win11 Neon Ed. -- astonishing bit of modding). Best.
