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

 think the wording was changed during the Updating

and the % removed.

It's the Updating Your System that I've never seen before.

Typical MS, the % progress was something useful, so they decided to get rid of it ?

It may only be changed for these servicing CU updates. I noticed that before & then it went back to % for the Build update.

Yes, I see also something new after firs restart: Screen goes black with text "Updating your system (xx%) at bottom of screen before come that new "Updates are underway..." without %.

That happened on all 3 Dev channel PC and one VM.

@Pauli O,

My second desktop same message with spinning dots after first restart, but on second restart just came up with a black screen with only the mouse cursor visible, and just sat there with the black screen..... 

Eventually it still completed the update and came up with 21337.1010.

After 1st restart:

After 2nd restart, no messages at all:

And eventually completed and came up...

On phase where you had black screen I had this: 0 - 100.

Hi Pauli, 

Looks like another bug, I did not see any message on the black screen, only the mouse cursor was still responsive so I just waited....

I saw something different this time.

After the initial Restart after it does the

1st part of the Updating when it did a restart

it went into an Updating  Your System, then went

into the 2nd part of Updating.

Everything updated fine and it did this on 2

different PC's.

I got exactly the same CK. Update took a long time @ 33 mins. Nearly as long as a normal Dev update.

Davy.
