Can I install Windows 10 lean on older Windows pc's ?

Thanks for the info. I thought it was over.

I should have left a disclaimer that it worked the last time I tried it, which was maybe a couple months ago. But I’ve done it many times since the free upgrade was supposed to have ended. I don’t do any tricks or pull any shenanigans. It just works.

They've probably just left it open for free downloads. The more people that upgrade to W10, the better.
 
I don't think Lean makes too much of a difference on older PCs since even old, unupgraded computers that meet Windows 10 requirements may still have at least 80 GB of storage. From what I can tell, Lean reduces 10's footprint but doesn't inherently make it lighter when running.
