Purchase Windows 10 with support for less than 2 years of support, or just buy brand new hardware for your entire business so you meet Windows 11 requirements. I know there are hacks to run Windows 11 on non-Windows 11 compatible systems, but Microsoft needs to rethink their strategy if they want to maintain market share (personally, I would love if some form of Linux were able to pull ahead in the desktop OS market, but we've been through this before)
