I have a Lenovo laptop that is 6 or 7 years old that works just fine.
The battery has long since had it.
We have Three Lenovos, plus a couple that MAY still work (one has bad memory)
They ALL work on 10 and work great. One is an Inspiron with that 32gig flashdrive, so, it can be tricky to update, but, I have a 1 TB hard disk plugged into it, so, not too much problems.
Then there is my 7+ year old Acer. Nice little system, not near eough usb ports, but, runs ok. It had some issues with Windows 10 at first, but, each new update has made it better and better. Only problem now? Overheating, but, that is an airflow issue. It runs Linux too, so, that’s a plus.
I find Windows 10 to be stable, easy to use, and have no problems running anything I want to run on them.
