Random Freeze and Unresponsiveness [Windows 10 20H2]

Having the exact same issue. After the update to 20h2, it randomly freezes and has to be manually shut off in order to restart.

I was 100% without issue until 20h2 dropped. Now its about 2 to 3 hours before it freezes to complete unresponsiveness.

Looking through the event viewer, its a generic error. Nothing specific to track down.

===UPDATE==

Reinstalled Windows10 Pro 20H2 via Windows Media Creation Tool. All updates, all firmware upgrades, newest drivers.

I'm still getting hangs. I'm reverting back to the update before 20H2. 20H2 is unusable in this state. I'm hard-restarting every 5-20 min depending on random factors. I've already been kicked out of a few calls.

Someone needs to seriously look into this. If it were an issue which would leave a clear log or a blue screen with a dump file, I would be able to fix it somewhere or at least know what's going on. As of now, I just get an Application Event mentioning whichever program hung first.

Yes, and Microsoft needs to fix this issue ASAP and question their QA testing.

That is ridiculous. I don't think Windows would come out with a solution for this. I have this issue since Windows version 1909 and now we're on Windows 20H2. Still no fix for this. And I think only a small number of people that actually have this issue that's why there is no fix available. Which is very disappointing. Windows 8 is much more reliable than Windows 10.

Update: I tried each of the given solutions none of them worked. 

After a couple of days of the update and constant force resrarting upon freeze the Laptop stopped booting. Thr backlit keyboard would lit but nothing on the screen and then it would turn off. Couldn't get it to boot. Took it to a Lenovo Service centre. They said the motherboard IC is at fault and would require a change. It costed me hefty Rs. 9000 which is around $150.

I was even asked to reset the system which I did. The laptop worked fine for exactly ONE week and then same problem. Took it back to the service centre and they kept the laptop for 3-4 days. They ran their tests. Installed 1802 version of Windows 10. Still the issue persists. Even they don't know what the issue is. 

So at this point I have a dead $1700 laptop a $150 service centre bill. 

Additional info: I bought this laptop from Best Buy, FL, US and currently I am in India. Lenovo doesn't have service centre to call their OWN, they have outsourced them to local firms and provide authorised ones on their website.

Hello, my name is Elias

I suggest you follow these steps

Turn off third-party Software and Services from system startup.

1° On the Desktop, press the Windows + R keys, type msconfig and click OK;

2° In the System Configuration window click on the Services tab;

3° At the bottom of the screen check the Hide all Microsoft services box and click Turn it all off;

4° Now click the Program Startup tab and open task manager;

5° When loading the task manager click the Initialize tab and disable all programs that are not Microsoft (right-click on the program and choose to disable), Close the Task Manager and click Apply and OK on System Configuration;

6° Restart your computer if prompted.

Note: This disables all third-party services and programs. You can later, if the issue is resolved in this way, enable the programs and services that will be booted with Windows selectively, rather than keeping everyone disabled. If the problem comes back after activating the startup of a specific service or program, the problem is exactly at the startup of this software and it is recommended to remove it.

If you remain the same behavior, use Troubleshooting to try to fix it. This solution is also known as Microsoft Fix it. Microsoft fix solutions can help diagnose and resolve problems in Microsoft products or third-party software that affects Microsoft products.
