In case this is of use to anyone.
With the impending withdrawal of free support for Win 10 in October, as the user of several perfectly functional machines which Microsoft says are non compliant, I have been considering my options. I have thought about going to Linux (but have several apps that would need Wine to keep working) or buying replacement hardware.
However last week I decided to try a forced upgrade to Win 11 on a couple of machines using a freeware product called Rufus to create an upgrade package that bypassed the compliance checks.
Both machines are Microsoft branded tablets, one from 2013 and one from 2015. Neither have processors considered compliant. The 2015 machine does have compliant TPM V2.0 capability, but the 2013 machine is only TPM V1.2.
Using the upgrade kit created, both machines successfully upgraded to fully activated Windows 11, although the newer machine needed me to dig around and remove a rogue device driver which caused the installation to hang. The older machine went through with no issues (albeit slowly). During the upgrade process you get a warning that you will not be entitled to updates, but as far as I can see the licence conditions don’t entitle you to them in any case.
Both work just as well (and as quickly) as they did under Windows 10, so for those machines the upgrade was the solution. I have a bigger desktop machine from the same era which has no TPM capability and a none compliant processor – when we get nearer to October I may try the same trick on that.
