Although correct that most companies should be ok that upgraded their equipment in the last 2 years, we have to remember though that some may have gone for a route of purchasing an older model which also had an older cpu that was available for sale from the vendors (Lenovo, hp, dell etc).
even 2 weeks ago you could find models with 7th gen CPUs for sale On their sites.
it would not be a stretch to say that a company might need to upgrade again if they need to use win11.
I agree with
@KittyGinger . This certainly was not a decision that was made in the past month. This was in the cards for at least a year. MS and the lobby of pc vendors just want to increase pc sales.
