Windows 11 upgrade

[DarrenO'D']

I have to upgrade our main office pc to windows 11, to run our payroll . Firstly the update couldn’t happen because the tpm was not enabled in the bios. I enabled that, the windows health check app says all compatible, but the windows update page still says the machine does not meet the minimum requirement?
Any advice gratefully received, all the hardware is way above the minimum standard.
Thanks

Does t have to be an upgrade - could you do a clean install?

Its not just about memory etc, but which processor its running. My Lenovo Thinkpad has the wrong I5 chip and wont run Windows 11. Cant remember where I found searh on chip manufacturers to check. On way out will look when return you could try googling chip completability for windows 11

The minimum specs are here

You could check the following:
Has Windows 10 recognised your TPM in Device Manager?
Are you on at least Windows 10 2004?
Is your BIOS set to UEFI Secure Boot?

For fks sake make sure you have a backup or three before going much further if you really have to do an in-place upgrade on an important office machine.

Make sure if you fiddle with bios settings you know what you did as fiddling with things like Secure Boot could make the machine not boot the existing OS.

On some systems you achieve his by "disabling CSM" in BIOS, which may not be intuitive.
