I was putting it off for several days because when Windows 11 did force itself my my Win 10 laptop it did bugger about with updating the bios against my will, which stopped Throttlestop working and knackered performance, such that I had to mess about downgrading the bios and disabling the bit in device manager which checks your bios. But I eventually let it do the 25H2 update and was surprised it left the bios as is. I can't see any changes whatsoever in general use though. Mainly waiting for the Start Menu update they seem to be holding back.
