Hp Pavilion pc 570-p0xx Motherboard 82F2. CPU intel core i5-7400 3.000GHz. 64 bits Windows 10.

CPU not suitable to install windows 11, thats what I understood. Want to replace it with a core i7 or i3 (more cores).

How to do this and where do I find an overview of the interior of the Pc. What is what? And how to change the product?

I hope You can help me.

The typical CPU for that series is an Intel 7th generation CPU.  What that means is the oldest Intel CPU supported is  Intel 8th generation (Coffee Lake, Whiskey Lake, Amber Lake).  Also typical is that you cannot install an upgraded CPU from a newer generation on a HP OEM motherboard.  In order to tell for certain, the complete model number is needed.  If you look at this thread, another user is asking about a different concern but in the post from @The_Fossette , he lists the possible model numbers that may be involved.

Please look for the one that matches yours.

BTW: there are ways to install Windows 11 on unsupported hardware if you wish to pursue that approach.

Thank you for your reaction. The Pc seriesnr is [Personal Information Removed] and prod.nr 1NJ74EA#ABH. If I understand you correct, I have to change the whole motherboard (now 82F2). I am not very techical. Do you have some suggestions?

Thank you.    F. van der heijden

According to this WiKi list, your processor the i5-7400 is 7th generation "Kaby Lake" and googling I read where there is support for certain Kaby Lake

The one listed in that article are socket LGA2066 or BGA and your system is socket 1151

All is not lost - you can fake the installer into letting win11 go in

I lucked out on my Area-51 7900x as it is socket 2066 and got blessed by Microsoft at the last minute.

I did some checking on the model number in question.  That motherboard will not accept a higher generation Intel CPU.  Since it is a such small case, I do not think it is worthwhile to try to adapt a retail board to that case.  So there are several choices:

1) leave it as is and still use Windows 10 until the support runs out

2) Go ahead with the upgrade but do it as unsupported, as indicated in @BeemerBiker 's  second link about installing Windows 11 on older PC's.  Keep in mind that it may not work to your satisfaction and/or may not get updates.  Also, if you are going to do a manual update, I would just get a new hard drive to install any Windows 11 stuff.  Thus keeping the old setup as is and on a separate drive from anything to do with Windows 11 until you are certain that it will work to your satisfaction on the unsupported PC hardware.  Strike that - I just checked the current setup - it has a 16 GB  M.2 Type: TLC Solid State Drive and a 2TB SATA hard drive.  You would need to take out both drives and then install a SATA drive or a SATA SSD.

3) make a new setup - new case, new hard drive, new CPU and new motherboard that has the necessary hardware for Windows 11

4) Get a new PC that already has Windows 11 installed.

IMHO, keep using the current PC until such time that you actually need a new PC.
