Has anyone upgraded board and processor in an HP Pavilion p7-1001 Desktop for Windows 11?

[firstfruitsfarm]

If so, what would be appropriate boards and processors? Not a gamer and would like to keep using a NVIDIA GeForce GT 730 video card.

Your PC dates back to about 2011.

Upgrading the MB and CPU also requires upgrading the RAM. The HP case has dated I/O options which would limit access to  current I/O available on new MBs.

You should also do a new PC case and a new power supply. 

What I'm suggesting is you should probably use the PC as is or get a new PC.

The P7-1001 shipped with W7 Home.

I would stick with W10 if you updated to this operating system.

Microsoft is going to offer a one year security update extension at $30.00 USD per PC to W10 consumer users.

@Bill_To,

To answer the OP's question, yes, there have been HP p7-1xxx Users who upgraded their Windows OS to W11, such as this example: https://www.userbenchmark.com/UserRun/52385063.

Our Senior Expert, @Paul_Tikkanen, explains how to painlessly switch to Windows 11 on so-called unsupported PCs: https://h30434.www3.hp.com/t5/Desktop-Operating-Systems-and-Recovery/HP-Pavilion-550-150-and-Windows....

Kind Regards,

I would also like to add that the AMD Athlon II X4 645 processor should meet the new W11 24H2 processor requirements for unsupported processors, since it supports SSE4A.

I didn't check W11 update options on the OP's PC.

I've got some older PCs running W10 with great results.

I might do the Microsoft one year at $30.00 USD security update option.

I have updated some PCs not quite as old as the OP's PC. The users aren't thrilled with their PC's performance when running the older PCs on W11. I may have to take the users back to W10. And some the users have encountered some hardware driver compatibility problems running W11 on older hardware.

My focus was spending money upgrading a very old PC vs a new PC.

Good to see all points of view. The OP has more options to consider.

This Site has the latest Microsoft W11 update recommendations updated on 12-12-24. I get the impression, just a guess, Microsoft may stop W11 security updates on unsupported hardware in the near future.

It appears Microsoft may now be doing a Desktop watermark on unsupported PCs.

I'm running W11 24H2 on an old Dell Inspiron 580s (ca 2010) with a first-generation Intel Core i5-660, a SATA SSD and 16 GB of memory.

It runs W11 just fine.

The Intel 1st generation core processors were the first to support SSE4.2

It's anyone's guess on how long Microsoft will continue to provide all of the cumulative and security updates on unsupported platforms.

They have been talking about that since W11 came out, so I am not overly concerned at this time.

The only thing that will never happen is for unsupported platforms to get the future W11 build releases via Windows Update like a supported PC does.

IMHO, trying out W11 on an unsupported PC is a low-risk venture since you can easily go back to W10 within 10 days of doing the upgrade provided you don't delete the Windows.old folder or the W11 upgrade files.

And W11 24H2 has support into late 2026, so at a minimum it outlasts W10 by a year.

Build releases have 2-year support.

I should have pointed out to the OP a W11 update option may exist, my BAD!

I was going to refer you to this thread to provide W11 update assistance.

I also like W11. But W11, in my experience, adds about 60 to 80 more running processes.

W11 seems to hit the hardware harder when compared to W10.

I always do a verified, recoverable W10 backup image on each PC updated to W11 in case the user has an unpleasant experience using W11.

Thanks for your rapid response. The only IOs I need are SD card, hard drives and optical drive. I have installed a much large power supply already. My OS is W10 Pro. I would like to keep using my NVIDIA GeForce GT 730 GPU. My present HD is WDC WD10 03FZEX-00K3CA0 SATA Disk, and it has a hp DVD A DH16ABLH SATA CdRom Device (CD/DVD record and playback).
An extended security extension would only forestall the inevitable.
I am leary of going to W11 on this unsupported device because of uncertain updates and runnability problems.
