Windows 11: “This PC can’t run Windows 11” error,

Legacy BIOS not UEFI, Secure Boot unsupported and almost certainly no TPM.

According to HP support that model has TPM 1.2

Actually, I checked the specs for the HP Zbook 17 G3. Apparently it does support Secure Boot, and while it had TPM 1.2 as supplied, it is field upgradable to TPM 2.015. Even the current Legacy install of Windows could be converted to a UEFI install without data loss. Only the processor is below spec for Windows 11.

HP does not support the computer model with Windows 11 drivers.

Many members have installed Windows 11 on computers that did not initially pass the Windows 11 compatibility checker.

A Windows 11 installation can be performed by a clean installation.
During a clean installation there is no compatibility checking.
Windows 11 has been installed by the clean install method in old desktops, laptops, and tablets.

A Windows 11 installation may be able to be performed by modifying the registry and files so that parameters are not detected by the Windows update agent compatibility checker.


The BIOS is old: 01.17.


1) Upgrade the BIOS: 0.17 > 01.54 Rev.A



2) Run both of these Windows upgrade compatibility checkers:

Post images or share links into this thread using one drive, drop box, or google drive.



3) Download and install: HP Support Assistant | HP® Support


4) Download and install: HP Image Assistant | HP Client Management Solutions


5) Run both HP Support Assistant and HP Image Assistant > check for upgrades

6) Download and install: Intel Driver and Support Assistant

This is what i got as an invalid specs\settings

The MSinfo32 confirmed the BIOS upgrade.

The BIOS mode may be able to be modified from Legacy to UEFI.
The disk drive may be able to be modified from MBR to GPT.

Once the above are accomplished you may be able to perform the steps in the EF bypass link.

Indicate whether you want to attempt the above steps on the BIOS and drive.


Indicate the progress with each step in the prior post.

In addition, the TPM firmware can be upgraded to TPM 2.0. However the one thing that cannot be changed is that this PC has an unsupported processor.

Personally I'd recommend that an unsupported device should stay on Windows 10, which will remain in full support until October 2025.

While almost anything can run Windows 11 Microsoft will not support it. There is a risk that at some time in the future they may stop providing updates to unsupported devices. It's fair enough to test Windows 11 on a spare machine, but it this is you main or only PC then it may be too big a risk.

Windows 7 has been unsupported for approximately 2 years: End Date: Jan 13, 2020

On one computer I'm using Windows 1809 .......support ended Nov 10, 2020

Many end users fail to upgrade their computer BIOS.


All of the above may place end users at risk for malware.

However the Windows 1809 continues to receive Microsoft Defender updates.

Threat definition version: 1.355.2706.0
Version created on 1/28/2022 5:17 PM

Windows 21H1 displayed the same as above with the exception:

Last update: 1/29/2022 2:18 AM


There are always risks.

It's unclear how to quantify the risk.


If a member creates a backup image and saves it to another disk drive or the cloud they may reduce any risks.

Also there is an EF thread in which a member displayed how they were able to downgrade from Windows 11 to 10 after the expiration of the go back period.

It appears that there is some flexibility to stay on Windows 10 or upgrade (unsupported) to Windows 11.

Does this mean that machines with “Intel(R) Xeon(R) CPU E3-1575M v5” has no luck to ever migrate to Windows 11?

There is a discussion here that covers how to make 11 work on non compatible devices. Should you do it.. I would say no but you can get it to work

For Windows supported CPU by version and manufacturer see these links:

Not supported!

Earlier in the thread a tutorial was posted on bypassing CPU and TPM requirements.

However there are prerequisites.

See the earlier post about BIOS Legacy / UEFI and partition MBR / GPT.

I know many will disagree, but I say if the machine is not compatible with 11 stay on 10, many will say it will it work fine but who knows what the future holds. If you do go that way look at @BunnyJ 's post #33

I agree but heck... it's not my device and I don't have a dog in the fight. All I can do is make a suggestion and then point the member to the right way to upgrade. Or should I say.. bunny in the fight?

All anyone can do is advise, sometimes though curiosity dictates that you just gotta find out for yourself

There are approximately 3 more years for full Windows 10 support (Oct 14, 2025).

If you decide later to upgrade there will be more people that have explored the frontier and have reported any issues.

Modifying the BIOS and drive partition structure improves security and has a faster boot and benchmark faster speeds.

I would tell them to make a dual boot. Keep their 10 install and make a separate 11 install to mess around with if they really want. Then if the rubbish hits the fan, they still have a working 10 install.
