Thanks...  In previous Windows versions (1909 & prior), optional updates would show as available in the Windows update section of settings.  Now in v2004 I had to click on the "optional updates" link to see it.  Don't know if that's the new normal, or it was like this for this big CU only...

 
 
One new feature that I do like is more choices when you right click on a tile in Start
 
 
 

Here are changes...can't believe this is optional  19041.423

fixing stuff is totally optional  ....

With all those "fixes & improvements", you'd think it would be a normal update.  Maybe M$ isn't that confident...?  Waiting for the beta testers...? 

 
Finally got the go ahead to update to 2004. So far so good. Will update if any problems arise later.

Good luck.  I had some flaky issues during install and for a bit in the first few hours post update, but running an update and picking up the latest patches as well seemed to have fixed it.  That was about 2-3 weeks ago now.  It actually blue screened in the middle of the updating process during one of the reboot/install cycles where it's installing stuff before fully booting.  Seemed to be a GPU driver issue though based on the minidump and other than one bluescreen also video driver related (moved to the latest driver AFTER the update to 2004) it's been solid since.  The reboot since though was during Folding so I think I had a bad work unit in that case, it wouldn't be the first time one caused that.  

I have had a couple hard locks & two bluescreens after updating to 2004 .... but that could also be from the new nvidia driver or the new AMD AGESA Bios update as well...
 So fairly hard to actually track down the culprit 

Only had some minor issues with gaming since 2004 and one issue with Soundblaster Z (had to reinstall drivers to get 5.1 back).  As far as gaming...451.85 solved that.

Reported NU Audio issue with Win 10 2004

Good day, I have a problem - in the game Assasins Creed Odissey, the sound disappears for half a second, it happens after ten to twenty seconds.
 
Moreover, the sound lags not only in the game but also in the browser if it is open in the background. 
 
The problems started with the Windows 10 2004 update, there were no problems before. 
 
I installed drivers 0.2.1.7 and 0.2.1.10 as well as 0.2.1.11beta and the problem is present on all of them.
 
 I output the sound through the monitor from the video card via HDMI (Nvidia HD Audio) and the problem was not observed, which convinced me that the problem was in my EVGA Nu Audio or in the drivers, but since the problem appeared after updating Windows to version 2004 (Win 10 Pro 64) then I think all the same in the drivers.
 
I am very surprised but the latest driver 0.2.1.10 was released on March 3, 2020, is it really such a good driver that there is nothing to add and everyone is happy, at least I'm not. Many manufacturers update drivers much more often and are sure to introduce new drivers with large Windows updates. I already tried a lot to solve the problem, but I still did not solve it, I was very upset because I did not expect that my EVGA Nu Audio would bring me such trouble.
