W11 upgrade for XW6600?

[cejixman]

Hello,

I would like to upgrade to W11. My XW6600 with Xeon E5420@2,5 GHz, 32 G RAM and SSD cannot upgrade directly to W11. No UEFI and STM 2.0 and Xeon not supported. Is there a bypass available for this situation? Thanks for any info!

Hi:

If you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2.

Two of the PC's I upgraded were an HP dc7800 CMT and a HP 8000 Elite CMT which do not meet any of the W11 hardware requirements.  Unsupported processors, no UEFI BIOS, no Secure boot and only a TPM 1.2 version security device.

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.

Here is a link to Microsoft's currently official description of ways to upgrade on non supported hardware.

Thank you Paul, I was not sure whether it would work for the Xeon processor.

You're very welcome. 

I don't see any reason why it wouldn't. 

Please post back and let us know the results.

Hi Paul,

thank you for your help sofar, I noticed that you filled out Rufus assuming W10 is running under UEFI, it is not however.Do I still fill out GPT? And I noticed there is an update of Rufus, should I install that?

Thanks for considering my questions, best,

Rien

You're very welcome, Rien.

I recommend you change the partition scheme to MBR in case you need to clean install W11 if the in-place upgrade fails.

That is the only thing you need to change.

You must use the version of Rufus I attached because all of the versions subsequent to 3.18 have the W11 hardware check bypass setting removed.

Cheers,

Paul

Thanks Paul,

I may have reacted twice, but to be sure everybody can read it: your instructions worked flawlessly! And indeed win 11 appears faster on my XW 6400 (which I used less than my XW 6600 :))

Best, Rien

Anytime, Rien.

Glad to have been of assistance. 

Cheers,

Hi Paul,

I also applied your method to upgrading a HP8470p with SSD and 16 Gb RAM. It also works fine, however sound is limited, the volume cannot be turned up sufficiently. I formatted the sound as CD, so the lowest demand, processor wise.  I installed the latest updates. In the device control tab of sound, video and games I found two High Definition  audio devices, both working normally (according to the general tab); 1 on bus 0 and 1 on bus 3. Both had the same driver version: 10.0.22621.608. I noted that in the events tab of the devices  the following info was mentioned:

Service: HdAudAddService
Lower Filters:
Upper Filters:
Problem: 0x0
Problem Status: 0xC00000E5

Would you have any suggestions to solve this issue? Thx for your effort,

Rien
