Why is my HP Pavillion 360 Notebook (5 Years old) with Win10 & 7100U CPU not compatible with Win11?

[Questor4]

I own an HP Pavillion 360 Notebook (5 Years old) with Win10 Pro 64-bit & an Intel 7100U CPU.

HP s/w referred me back to Microsoft to run their PC Health Check to examine Notebook hardware compatibility, which says that my Pavillion's 7100U CPU is ***not compatible*** for a free update to Win11 for some undisclosed reason.  However a Pavillion 360 Notebook made a few months later running an 8100U is considered Win11 compatible

As a result, I have a few questions:

1.) Why does Microsoft and HP list the Intel 7100U CPU as not hardware compatible with Win11, but the Intel 8100 CPU is compatible?
2.)  Can I purchase a CPU upgrade to swap the 7100U for a matching 8100 CPU?

3.) If a hardware CPU swap is not possible, should I purchase a new and complete Win 11 Pro or Win11 Home and do either a new install or else an update from Win10?

4.) Which Win11 features/functions will I lose if I manually install Win11 with the Intel 7100U CPU?  It seems that some Win11 Security features may not function because the 7100U CPU supposedly does not have Intel Xeon CPU security built in...

HP wants to charge me money for tech support to answer these basic update questions that are not documented on the HP website... It seems to me that HP is more interested in trying to get me to buy a new Notebook than answers these simple questions...

Hi:

Microsoft drew the line at the 8th gen core processors.

The processor is not upgradable unless you replace the motherboard and that would only be if your specific notebook's model series offered motherboards with the Intel 8th gen core processors.

You would be better off buying a fully supported W11 notebook due to the high cost of replacing the motherboard.

You do not need to buy a new operating system.  Use one of the several W11 hardware check bypass methods to upgrade to W11. 

I found this method the easiest way to do that.

Before you try to upgrade to W11, I recommend that you make a system image of your current W10 installation prior to updating to W11, so you can easily reinstall W10 in the future.  I used the free Macrium Reflect software to do that, under the Backup at Home section. 

Along with the system image, make sure you create the bootable DVD or USB rescue drive you boot from to access the system image stored on your portable hard drive.

I installed W11 on 11 different HP and Dell notebook and desktop PC's and it runs just fine on all of them.

They also get all of the cumulative and security updates that Microsoft has released thus far.

I check those PCs against one I have that is fully supported for W11.
