Random Freeze and Unresponsiveness [Windows 10 20H2]

I would suggest you hold on updating by downloading the Microsoft tool "Windows Update Show/Hide Updates". In mean time, I suggest you visit the Optimize Drives(disk defrag) tool on your system and set it to weekly on all drives/partitions except for the zone where your OS is installed, there disable defragmenting(in my case, the fragmentation always stays in the 10% range, so there really is no need for it). That's the solution for the freezes/hangs I'm currently focusing on and hopping it works. This is not a fix, just a possible workaround to see if the defrag tool is the culprit that freezes your system. If it is, then you need to go to Event Viewer to where the process fails. Note that the process fails if there is a file or zone on the drive or partition that is damaged.

Another possible and probably a stupid fix should be here edge://flags/, you get there by going to Setting in your Edge browser and typing the rest. Then search for Delay Competing Low Priority Requests flag and disable it.

I'm not entirely sure if there is a way to know but this issue has been going on for a while now, at least for me and none of the update to this day address this issue. One thread I saw few months back saying that because it only affected a small group of users, Microsoft isn't gonna pay that much attention to fix it. They rather add more stuff for their next update and eventually break more stuff because of incompatible issue and fix issues that are affecting a larger group of users. 

I am waiting for 21H1 update as well because it supposedly more "stable". If the update doesn't fix the current issue, then I don't know what else to do to reach to Microsoft and make them aware of this.

Well, after installing KB5001391, I had one more crash shortly. However, only after this did the "News and interests" feature, also part of this update, show up. So it is conceivable that the patch of our real interest had not been live first. Since that 2nd reboot, my system has been up and running, i.e. for 5.5 days so far.

To put this in context, my previous incidents happened at such intervals:

4/14, 4/18, 5/2, 5/7, 5/9, 5/9

Should my system crash again, I'll (try to remember to) notify you guys...

I have a similar problem with a brand new Dell Inspiron 15-3505 out of the box! 

Edition    Windows 10 Home
Version    20H2
Installed on    ‎5/‎4/‎2021
OS build    19042.964
Experience    Windows Feature Experience Pack 120.2212.2020.0

One "factory reset" fresh start and recovery within the first week.  Tried all the recovery options I could find posted here and elsewhere.  "NO JOY"  Nothing worked.  Discovered a work around that works for me.  ALT CTRL DELETE followed immediately by opening the Task Manager (click twice).  Miraculously, it unfreezes user input (until the next time).  Frustrating but necessary until I can install a new hard drive on my WINDOWS 7 PROFESSIONAL machine.  I made the terrible mistake of believing Microsoft had worked the bugs out of WINDOWS 10.

New Windows 10 update could finally fix a huge problem with drivers | TechRadar 

This could be the fix that we all been trying to get. Have a read.

hope so. i was testing my pc around 3 months to try discover the problem. and i'm almost 100% sure that the problem for my stuttering is realtek audio or lan driver incompatibility with windows. lets pray for this update.
