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

Both my machines updated without issue. Glad to see that the opencl.dll issue has been resolved when running sfc /scannow.

Hi Ck, Dell #2 finished in 1 1/2 hours about the same as usual for this HDD, In using Dell #1 I find that I really like the spacing in File Explorer. It is so much better for these Senior eyes to differentiate the categories. It is not wasted space.  

I'm probably older than you and I hate it.

It should not be the default !  😜

Edit: Dell #1 does not have the News & Interests, and Dell #2 does have it. Personally I have turned it off as I do not like the hover over & News section does not have the News Sites that I visit. I look at both sides of issues & do not like to be forced to read only one side of the news decided by others.

Same here...two 64-bit Pro installations completed through WU without incident.

That post was made by me 😄

But also another user with an NVMe SSD reported no issues at all. 

Hi Willian, 

I have NVMe SSD and no problem with this or previous builds.

Is it a specific brand or type of NVMe SSD or driver ?, 

I have a WD_Black SN750 500GB SSD.
Maybe its brand-related indeed.
