Product: HP Pavillion 500 254ea
Operating System: Microsoft Windows 11

Hi,

 

I have a 12 year old HP Pavillion 500 254ea which I have managed to get to run Windows 11. Can't have any of the major updates etc., but security updates are fine, apart from that, happy with all other aspects.

 

What happens when Microsoft Secure Boot certificates updates are issued.

Will this PC be affected? Stop running? I am pretty sure that I cannot install any new Boot Certificate?

 

Is there anything I should do before these updates.

 

Any pointers/suggestion, gratefully received.

 

Kind regards

Mike
