Random Freeze and Unresponsiveness [Windows 10 20H2]

Has anyone with the issue tried this update by chance (or made sure it's installed?)? https://www.bleepingcomputer.com/news/microsoft/windows-10-kb5000842-cumulative-update-fixes-freezing-issues/

I had the freezing problem when I had moved forward from 2004 to 20H2 and then I rolled back to 2004 and the problem went away - I'm still on 2004 and I won't install a new version until 21H2 later this year, but I am continuing to monitor this thread as this is a very concerning problem. Hoping an actual solution is found at some point since some people who have now tried 21H1 are still having some issues as well.

EDIT - Also has anyone tried disabling "Hardware Accelerated GPU scheduling"? I saw one post on reddit where someone had mentioned that resolving system freezes for them. So just something to try. Since I am not currently having the issue with v2004 I can't test any of this stuff.

First of all i want to apologize for my english, isn't my best point, but i will try to do my best... I want to share my expirience with you.

Few weeks ago my PC decided by itself upgrade to windows 10 version 20h2 from 1909 (that one was completly stable for me, 0 crash). After that, i start having system freezes or crashes with no blue screens, no error codes, nothing on the event viewer... Just the mouse work, and the sadest thing, i had to press the pc button to hard stop every time.

Then, i start searching on google or forums like this, about that problem, i will share here some of like 100 things i've tried this days ago.

• I did the "sfc /scannow and dism restorehealth. (Not work)
• I updated manually 1 by 1 all my drivers to the latest. (Not work)
• I did a clean start-up with only windows files and software, disconnecting all my usb ports except mouse and keyboard. (Not work)
• I disabled things like "Intel Rapid Storage". (Not work)
• I tried to put my CPU and RAM at default Mhz, before that i had "Gameboost" on bios from "MSI Bios" and XMP Profile enabled. (Not work)
• I uninstalled my AVG Antivirus and did a config for Windows defender. (Not work)
• Did a clean install of Windows 10 21h1 taked from Microsoft Web, doing all the steps typed before again (Not work)
• Did a clean install of Windows 10 2004 taked from Rufus, doing all the steps typed before again (Not work)
• Did a clean install of Windows 10 1909 taked from Rufus. (Had 0 crashes on a week)

Actually im a computer technician, and i really don't know why that happen's, the sadest thing it's no error codes, no error msg, nothing. I don't know if its about usb drivers, if it's something about GPU (Cause on task manager, two times i had the error, i can see the % usage of GPU stucked on -1% one time, and the other was on 100% without playing nothing). I will apreciate if someone find a solution about that problem cause it's so annoying. Im sure i've tried more things than listed before, but i can't remember all, i just know that no one works for me.

Update. My laptop froze 4 times within an hour lol. I don't know what else to do. I'm just scared that one day my laptop would stop working completely from all the hard reboots.

So I brainstormed with some devs I worked with in the past, not affiliated with Microsoft, and we are now looking at the power plan and USB power management possible workaround. Other than this, I can't see anything else, so if anyone here wanna try it as well, the possible workaround looks as follows:

• In Device Manager, go to USB controllers and there for every USB hub, uncheck "Allow this computer to turn off this device to save power"
• Now you need to enforce the procedure above: go to Power Option, and make sure your current plan is set to Maximum Performance. Go to Change Plan Settings -> Change Advanced Power Settings and under USB Settings -> USB selective suspend settings, set both options to Disabled. Under PCI Express -> Link State Power Management, make sure both options are set to Off.
• Also make sure you have "Turn on fast startup" is also disabled. This "feature" just sucks.

That's all I have left lolz. Hope this works.

Thanks for the input. Imma give it shot. I've tried the second and third options before, but it didn't work for me. But that's my current settings. But I've never tried the first one. Hopefully it will work.
