How come no new build? Been 8 days.

Monday was Memorial Day.

I just saw the other comments. Last Friday was probably a slim crew out there also. Even though they are Microsoft and should think/feel/work/sleep/eat/etc. like robots, they are somewhat human, like us.

A 1-day holiday logically shouldn't push anything back more than 1 day.

I agree.

Maybe they are working on Windows 11 ?

Hi folks

If this is to be a "Near RTM release" - I don't think much of it as it fails to install on a physical computer -- It installs properly without issue on a KVM VM !!!

Here's what I get when trying this on a physical machine -- disconnected everything apart from the Disk to install on (SSD) and 2nd internal SSD.



On a VM - no problem



Any ideas

Cheers

Not surprised. I couldn't even do my usual upgrade install (I only install these builds on the hardware) from 21370 (which ran perfectly with the same device drivers installed and the same 10-bits-per-pixel toggle enabled) until I narrowed the issue down to a single setting in the AMD Adrenalin driver interface--the 10-bits-per-pixel switch I outlined in a previous post in this thread. Yes, these builds seem to have multiple bugs relative to their installing correctly--yours failed on a clean install; mine failed on an upgrade install. I did, however, spend entirely too much time troubleshooting 21390, but at least I found the culprit and was able to finally install the build.

This is what gets to me about Win10 development--Microsoft is frequently tosses out the baby with the bathwater, imo--constantly reinventing the wheel instead of simply building on top of a stable code base--the same device drivers were fine all the way through 21370--but something changed all of that in all the subsequent builds. My theory is it has a lot to do with the massive HDR improvements and capabilities they are putting into these recent builds: current GPU device drivers may be choking on them for some reason. But we shall see...I like what they are doing and 21390 HDR works very well these days...a nice improvement, but of course it's only an improvement if the darn builds install!...

10:00 AM Redmond time has come and gone. Still no new build!

Bunch of slugs! They haven’t even the decency to send us a note that there will not be a build this week.

It's a sad thing. I would not expect anything until next Wed the 9th and then I won't be anything except new icons, if that. This build was very bad - green screened for no known reason - and I just wiped the drive and installed another version of Windows dev but it attempted to overwrite grub and installed its boot manager of my linux ssd without a bye your leave. Windows 11 had better be something special but expect 1) It won't be called Windows 11 and 2) it won't be special in any way. Can anybody remember the last time they announced improvements to Hyper-V? Neither do I.
