1st generation AMD Ryzen CPUs

Windows 11 supports my HP Envy laptop (I had a pop-up advising me to upgrade), but not my Dell Inspiron Gaming PC.

I ran the PC Health Check on my PC and everything is fine except the processor, which "isn't currently supported for Windows 11"
So I checked the list of supported processors and in fact, my AMD Ryzen 7 1700X Eight-core Processor was not on the list.
With a bit of research, I discovered that my processor is 1st generation Ryzen, which Windows 11 does not support.

This is a good gaming PC and is only 3 years old. I'm amazed that Windows 11 doesn't support it.

So I have a few questions and quandaries:

• Has anybody tried networking a Windows 10 and a Windows 11 system? I am reluctant to upgrade one without the other as I need them to work seamlessly together on my network.
• I read a few old articles indicating that Windows may eventually extend its support to 1st gen Ryzen. Does anyone have up-to-date information on whether this is a real possibility or not?
• I suppose I could keep both laptop and PC on Windows 10 until 2025. The only reason I'm interested in upgrading is the increased security of Windows 11, and some concern that although supported, Windows 10 will not receive as much attention anymore.
• I suppose my only other options will be to upgrade my PC with a new PCU (which could be expensive) or try the methods for installing Windows 11 on incompatible hardware (which I don't like the idea of much).

Hey, I've transferred a couple of files from my pc (win 11) to my brothers and it worked no problem. That is the most basic of things though But i dont see any reason why it wouldn't work so far.

As for extending support, I personally don't think that they will, if they were going to i'd say they'd have done it for launch, However i could be wrong.

As much as the 1700x is a really good cpu it is nearly 5 years old since it launched which puts it in the same bracket as the folks on the 7th gen intels with exclusion of a few.

No problems Networking 10 and 11 here, 2 PCs on 11 and 2 on 10.

Before contemplating upgrading the CPU on the Inspiron, you might want to check if Dells Motherboard will support 2nd generation or higher, Dell being somewhat different, if similar to other first generation boards in theory it ought to support second and third generation, I swapped a Ryzen 5 1600 for a Ryzen 7 3800X on an Asus mother board.

Microsoft will not be changing the list to include anything else as the excluded CPUs do not have the required features and drivers for Windows 11, there is a lot of rubbish that's been posted about extending support.
You can run 11 on a first gen Ryzen however it would be unsupported with no guarantees that you will get updates or that it won't stop working in the future. Currently unsupported CPUs are getting updates and MS have made a registry fix available to enable 11 to be installed on unsupported hardware at your own risk, plus there are several other methods, see this thread Let's run Windows 11 on an incompatible hardware

Yes, any system that can run Windows 10 64-bit can be made to install Windows 11 too, either directly (supported) or by hacking (unsupported). Read all about it in the appropriate thread suggested by clam1952 above. The only difference on an unsupported system is that you must hack setup for either a clean installation or upgrade from 10 or from an earlier Windows 11 build to the latest build. All other updates do not check compatibility and install automatically through Windows Update, so do not worry about security. Regarding drivers, all Windows 10 or 8 or 7 or even Vista 64-bit drivers will also work on Windows 11 with the exception of some Intel graphics drivers that are on purpose blocked by Intel to install only in Windows 7 64-bit to force you upgrade to newer hardware. Even these can sometimes be forced or you could install the respective Vista 64-bit drivers instead. So no worries about drivers either.
