Next year Windows 10 goes End of Life. Microsoft will undoubtedly push windows 11 hard, but a lot of machines won’t support it leading to a few economic points of interest:
The demand for new machines will be high, driving up cost.
The supply of unsupported machines will be high, driving down the used market.
