I upgraded from an Intel Core i7-12700KF with an MSI B660M Mortar WiFi motherboard to a Core Ultra 5 250KF with an MSI B860M Mortar WiFi motherboard. Both systems use DDR5, but the socket and chipset are different, so I had to replace the motherboard as well. I'm running Windows 11 Home and would strongly prefer not to perform a clean installation because it takes a long time to restore my settings, game configurations, and other customizations. I've already installed Intel's Platform Performance Package for the new processor, and so far the system has been stable with no crashes or gaming problems. Can Windows handle the old chipset and hardware drivers automatically, or should I remove them manually? Is a clean install really necessary, and how can I verify that the new CPU is being scheduled and performing correctly rather than being affected by remnants of the old hardware setup?

A clean Windows installation is the safest and generally recommended approach when changing both the CPU platform and motherboard. Windows may boot and appear to work normally with the existing installation, but old chipset, storage, networking, and vendor utilities can leave behind conflicts or cause problems later. In practice, troubleshooting those issues can take longer than reinstalling Windows when you have time to do it properly.
That makes sense, but I’m not seeing any problems right now and would rather postpone the reinstall until it’s more convenient.
