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.
Are you all ready?
You likely just need to enable TPM through the BIOS (each manufacturer calls it something different).
I’m in a similar boat, but am going to use W10 EOL to probably jump ship to Linux - if not at the very least switch to Windows 10 LTSC.
