Windows 10: System freeze every 26 hours, Windows Defender causes system freezing

Hi Guys,

This really hit me badly. Hope I can get some ideas from all of you!


I had this mystery for several months now. a production server appears to be freezing every 26 hours. during the freezing, I can not RD to it, IIS sites hosted on it are not responding. the freeze lasts around several minutes then everything back to normal. The server is not on heavy load, has plenty available memory and disk space, up to date.

Yes, it's every 26 hours. I can't figure out why


Say it happened at 1AM on day 1, then 3AM on day 2, and 5AM on day 3 then keeps going till 11PM, then 1AM again.

It's Windows Server 2019 Standard 1809, OS build 17763.914

After trying quite long time, I was able to locate the cause to be related to Windows Defender scheduled tasks. But how to I 'fix' it?

In Task Scheduler, Task Scheduler Library, Microsoft, Windows, Windows Defender, there are 4 tasks listed.

1. Windows Defender Scheduled Scan
2. Windows Defender Cache Maintenance
3. Windows Defender Cleanup
4. Windows Defender Verification

#1 is ok. It has one trigger defined to run at 2:30am everyday, and always run at scheduled time at around 2:30~2:50am everyday


#2,#3 and #4 are the tasks that run every 26 hoursnone of them has trigger. Task history shows they were running 5:02am on day 1, then 7:02am on day 2, 9:02am on day 3. Yesterday they run at 8:10pm. These time match system freezing time.

This results in trouble especially when they are on their 'day shift'.

Could anyone share thoughts on how to change the every-26-hour behavior, so that at least I can schedule them task 2,3, and 4 to run during night time?

Or even better, to make them not cause system freezing, but seems that would be even more complicated.

Appreciate your help!

Windows 10 system freezing

Installed Windows 10 about 1 week ago. After working on they system for about 10- 15 minutes. The system freezes up, it will freeze when I am using internet explorer, opening programs, it is very non judgmental as to when the whole system will freeze. Once
it freezes up, there is nothing you can do for about 1-2 minutes. After the 1-2 minutes, they system will work normally. It tends to freeze up about 2-3 times within a 2 hour period. I have done some internet searching and nothing quite fits what is happening.

Suggestions?

Thanks!

 

System freeze when running the HWMonitor freeze

Hi,

I appreciate if you could answer few questions to narrow down to the issue.

• 
  Is the issue specific when you run the application?
  
• 
  Did you install any third party security application?
  
• 
  Did you receive any error message when the system freeze?
  

If the system freeze only because a specific application, then it would be due to the program incompatibility or when the application needs a repair. You may try uninstalling the application which you think causing the system freeze and check
if it helps.

If the issue still persists, run the System Maintenance troubleshooter finds and clean up unused files and shortcuts and performs maintenance tasks.

• 
  Type Troubleshooting
  in the search bar.
  
• 
  Select Troubleshooting and hit Enter.
  
• 
  Click on View all in the left pane of the window.
  
• 
  Select System Maintenance.
  
• 
  Click Next and follow the on-screen instructions to complete the troubleshooting process.
  

Hope the information helps in resolving the issue related to the system freeze. If the issue still persists. We will be glad to assist you.

Thank you.
