KB5004123 CU Windows 10 Insider Preview Dev Build 21390.2025 - June 14 Insider

Preparing for Insider Preview Builds of Windows 11

Who of you are running the latest builds as your daily driver?

Because I need Hyper-V nested virtualization support on AMD hardware, I am seriously considering upgrading my laptop to these dev builds. Currently I am on RP channel.

Anything I should be aware of that does not work properly yet?
@Kari and others.

I thought I already did ask 2 questions, which of one got replied to...but the important one did not.

I use nested virtualization quite extensively. I have written a tutorial about, which you most probably won't need. The tut includes a simple PS script to enable nested virtualization on your virtual machines.



You can download the script from my OneDrive:

Download

Tutorial: Hyper-V Nested Virtualization: Run virtual machines on virtual machine

Nested virtualization works in all W10 PRO and better editions, regardless of the channel.

Thanks Kari, as you suspected, I already know how to setup nested virtualization. It's just that on the latest RP builds this isn't yet implemented for AMD hardware.

So I need to switch over to dev builds now. Are the builds stable enough to use for not so serious "work"? Nothing mission critical going on, on my systems, just don't wanna be reinstalling everything in case it's unstable.

Well, everything does work properly for me so I didn’t include that.

Glad to hear

I can't fit 500GB system image anywhere at the moment, or I would have a backup already.
