Replacing old Intel CPU/Mobo with new AMD CPU/Mobo

I'm currently running Windows 10 Pro (upgraded free from Win 7 some time ago) ; with a Retail Activation linked to my Microsoft Account.

I have an Intel i5-4690K on an Asrock Z97 Extreme6 motherboard with 32B of DDR3.

I am looking at replacing this with an AMD Ryzen7 5800x, and 16GB of DDR4; though I haven't decided on which motherboard yet, probably will be the Asrock X570 Phantom Gaming 4...

Thus far, everything I've read (even on Microsofts own website) states that I do NOT have to reinstall windows; that Windows 10 will just need to be reactivated and then I will just need to change out the necessary drivers. Has anyone had any experience with this succeeding?

Well I don't mind having to do a full reinstall, its not that hard to set it up via USB stick...

Its just one of those things we all prefer to avoid, if its not completely necessary, you know...

Hence I was a little surprised when I read that it isn't, necessary... even when changing chipsets like I would be doing, and surprised even more when I read that as the "accepted solution" from a microsoft tech, on answers.microsoft.com....

...and oh yea, no, I dont still have my old Windows 7 install disk... well, I do... but its in some storage box, buried under a dozen other such boxes and junk; all locked away in a storage locker a couple miles away... yea we cleaned out the apartment a couple years ago, and it ended up in a box of old computer stuff that went into storage.

The odds are good that you'll be able to make the move. I have done the move from an Intel system to an AMD one successfully under Windows 10.

However, the advice from "cereberus" is good.

You will have two main obstacles:
1. UEFI booting v. Legacy BIOS (CSM mode) booting. If you are moving from UEFI to UEFI or from legacy to legacy, it's not a problem. Going from legacy to UEFI is easy - you just need to be prepared in advance for the switch.

2. Disk/drive/storage controllers. Switching modes/types of controllers is a problem, but, again you can prepare for most of them. If you are going from/to the same type, SATA (AHCI) to SATA (AHCI), NVMe to NMVe, it's likely not to be a problem. But if you are going from SATA (IDE) to SATA (AHCI), or SATA to NVMe then you will need to uninstall drive and storage controllers from the old system and set it to boot into Safe Mode, then shutdown and do the move. You may have even more difficult problems going to a computer that requires Intel Rapid Storage Technology (IRST) drivers because those have to be installed on the old system before the move.

As long as you overcome those two potential roadblocks, you should be just fine. Be aware that some programs (besides Windows itself) will detect the move and possibly lose their activation status - such as Microsoft Office.

Nothing else is going to be changed, other then the CPU, motherboard, and Ram obviously.

Main boot drive is NVMe.. a Samsung 950 Pro 512gb m.2. Then there is a second Samsung Evo 500gb m.2 in the secondary m.2 slot and everything (2 SSD's and one Blueray Drive) else on SATA; only thing on those SSD's are my Steam Library folders and some other games! lol I also have an old WD 1tb HDD but I'm thinking about retiring it.

A Radeon RX 580 video card, and an old Creative PCIe Sound card, I forget the exact model, some Fatality Titanium series... and I have the latest drivers for each.

Everything will be staying the same, and hopefully all plugging back into the new Mobo just as they were plugged into the old one; same m.2 ports, same sata ports, etc.

You should not have any problems then!
