You probably know this, but for others who might not: MS is now allowing some/many/all (???) people to extend the security updates for Win10 for another year free of charge. You have to go into the Windows update area and click a button to accept. At least in the USA, this seems to be a somewhat newly available option, as it was there the last time someone asked me to look at their laptop to see if I could upgrade it to Win11.
