Windows 10 Feature Update 2004 taking too long to install

I wonder how many have just decided to pitch their older PC's in the trash and buy new ones because of this ridiculous update.  Why wasn't MS in the witness box along with Facebook, Google, et. al. in front of Congress?  I have multiple machines that ran quite well on Windows 7 and now don't run very well.  Each of these machines took at least half a day to "update" to 2004 and don't appear ONE BIT different to me.  One of my major disputes is the thorough integration of Edge--you cannot uninstall it.  Isn't  MS stealing user data just like the others?  Isn't MS in a MUCH better position to track everybody on earth actually OWNING the OS of nearly EVERYBODY on earth?

Has anyone successfully completed this update?

Yes I understand your problem. I have a Fast gaming laptop. Good Internetcconnection and memory. On my second day of downloading this update. Left it on for the last 48 hours whilst I went to work over the weekend. Still on 47%. What ever happened to Microsoft. Truly appalling. Tried all the fixes and recommended advice on line but still no joy. Are we really expected to wait 2 to 3 days for an update.

I would like to understand exactly why the 2004 process seems to touch every single file and every single device driver and every aspect of my PC's while it "updates."  What's going on here?  I actually got through the process on each of my 8 machines (desktops and notebooks) after 6 to 8 to 12 hours, and NOTHING seems to have improved or changed.  Except Edge is now thoroughly weaved into the system and is irremovable.  I don't use Edge.  Won't use Edge.  Don't want Edge.  I don't use OneDrive.  Won't use OneDrive.  I don't want OneDrive.  What's going on here?  What else is going on here?  I don't think it's a question of "What ever happened to Microsoft."  I'd like to know what instrumentation they have installed on my computer.

Read all the comments in response to this post as of August 5th and did not see any information on my question but glad to see I was not the only one having an issue with this update. Today 8/5/20 is the 3rd or 4th time of me trying to update. At this moment it finally got to Downloading - 99%. Can anyone tell me what happens next after Downloading says 100%. Does it have to install and reboot? I am guessing I will leave laptop on this time until it is done. The 1st try I had gotten an error message and will I looked it up online said means files are missing. The other times, it was just stuck like it is now and I finally shut off laptop and went about the rest of my day.

First step is patience: If you haven't actually received a failure let it run (which you said you're going to do) but you get 0 savings from restarting the process so might as well let it go till it's done.

As for the first question: After Downloading you will get an Install part within that same Windows Update tool *pre-reboot. That's actually where I spent the vast majority of time in the first Phase (you probably just have a much slower internet connection than I do). "Installing" took many hours.

Once the Windows Update "app" Phase is over (You click the Reboot button) then you move onto Phase 2 which is in that "not in the OS yet" green screen saying windows is updating with a percentage. This whole phase took me 14 hours and was roughly the same amount of time if not a bit more than the "Installing" time I spent in the app. SO if you're just getting done with "Downloading..." you've got a long ways to go but at least at that point you shouldn't need an internet connection anymore.
