RS-Prerelease Build 21337 is out to Dev Channel + KB5001618 to .1010

Ok, cool... the results of that will be interesting.  As you know, mine was/is via WU and a VM. Maybe, there was black with nothing for a while, too.  So, yes, let's see what there is without a VM involved nor WU. I'm used to working the peculiarities of having the VM go. So will be cool to know what you get.  I can just say is it seems we all had similar 'process' screens that were different than in the past. The whole process with this Cum going seemed different than what we are accustomed to with them, time taken, screens seen, et al.  I trust Windows must be looking into something with this exercise.

BTW & FWIW, I am enjoying using the IB & particularly this one & going forward.  Compared to Win10, there is just something about the 'look & feel' of the IB that's just 'nicer'. IDK, 'big', bright, clear, lovely, consistent icons everywhere, spacing AND all the desktops with their own names, accent colour, backgrounds (Looks so cool & adds to knowing which is what by its picture) & positions, Dark more wide-spread, Windows Terminal (with tabs), colour picked for Edge and more. It looks great and heaps of cool things to explore.  It's going to be a hoot as we see more & more evidence of Sun Valley.  Forgive if my thoughts on this have bored you.

>"I do not think it's a bug.  As I has said I saw the same unfamiliar screens, black "Updating your system 100%"

I think that black screes with text "Updating your.... " is by design but if that black screen without text is bug.

 

Correct, a black screen with nothing, but the mouse cursor for several minutes is a bug...

I will try the same W.U. update from a clean install of 21337.1000 to see if the behavior is different...

Edit:

Same behavior after a clean install of 21337.1000 on Dell XPS 8300.

W.U. downloaded and installed the updates for 21337.1010 and asked for a restart, 

1. After restart, it came up with the same message "Updates underway... " plus spinning dots.
2. Second restart came up with the black screen (No messages) just mouse pointer.

    (I could see the activity for several minutes because this PC still has the HDD or SATA SSD activity LED 😉 )

3. Another restart and again the same message "Updates underway..." plus spinning dots.
4. Login screen and finally up at 21337.1010. 

No other message and no progress % indication ever.

Exactly the same behavior on the MSI GT70-0NC Laptop.

I do not think it's a bug.  As I has said I saw the same unfamiliar screens, black "Updating your system 100%" & the other 'new' "Updating, don't unplug" with no progress indicator.  It all did take a while, but was successful.  It's just WIP testing things, trying things (delivery methods). I do find MY 337 is running very nicely & better than the previous 2 Builds.

Here are 2 situations seen with 21337.1010 updates.

For whatever interest there may be, here's a note about today's events for mine, together with remarks in the thread.

The Cum .Net taking it to 337.1010 installed. Albeit all went smoothly & incident-free... I had the same (unfamiliar) screens mentioned. And I whole-heartedly agree about not having a progress indicator of some sort.; percentage, circle, bar, IDK, but something, absolutely.  I was about to go somewhere and realised I had it going and no clue if it would be short or long wait... shall I go or shall I stay, I mean come on, geeez.  My ESP, nothing. Tell me, show me, give some hint 😒🤨  Ok, I'll stop being silly.  May I have the FH link, please, to upvote, show some support, strength in numbers.  Thanks.

337, aside from bugs we, already. know & speaking for myself... between it & Edge, Holy Cr@p things sure are snappy & quick.  Talk about responsive.  Well, anyway that's how it's feeling, to me.  

I cannot help but notice all the Fluent Design icons everywhere.  Personally, I'm not finding it hard to get used to what's coming down the road or what's up the road, on the horizon.   And I find it downright fun seeing Sun Valley things emerge in our IBs. I often tell & show people, "Look what's coming, it's cool stuff". If I may, on a personal note: I have beta tested since Vista and of all the shiny new OSs & funky stuff along the way, over all the years of Launch Events, et al.... THIS is the most exciting time for those who are now called Insiders.  It's quite cool to be part of what is a fairly historic moment in Windows history AND see it all in advance. We may be bug hunters, which can be frustrating, but what is coming should be thrilling.

There are some items of note in this Build, I think.  Windows Terminal, Windows Notepad, Power Automate and I do REALLY like what multiple desktops are, now❗ Can have an appearance that goes with the sphere/spirit/subject of each different desktop... and, if the OS Accent Colour is set ✔️ to Auto-Select, then that will be what is apt for each desktop and each desktop would be different in that regard, too and their positions can be easily changed via a Rt Clk menu, now 👍👍. Also, that, now, search results panel is Dark... more wide-spread uniformity visible more & more as time passes. 

If, currently, unfamiliar, read about Windows Terminal & Power Automate Desktop, HERE & HERE, both items are very interesting. And finally (as in, I'll shuddup, now), here are some pretty pictures 😀
