Windows 10: System random hangs after KB5011563

I'm running Windows 11 Pro 64-bit on a new Intel i9-12900 system with 64GB of RAM. I'm using on-board graphics only; there are no peripheral cards plugged into the motherboard an Asus ROG Strix Z690-G Gaming Wifi board.The Reliability Monitor indicates that my system started experiencing random hangs on April 8 the first time there was an unclean shutdown, at which time the most recent Windows update the system had received was KB5011563, on April 3. Unfortunately my restore points prior to this date all vanished, leaving only the most recent restore point something I'm certain I didn't

Windows 10 random freeze

Hi,

Did you make any changes recently to the computer which may have led to random freeze?

Random hangs are often due to damage to the Windows configuration, faulty hardware, or malware. However, because this behavior is random, it can be especially difficult to identify the proper cause.

Random hangs can also be caused by other faulty hardware. Consult with your PC manufacturer to run available hardware diagnostics. This could include:

• PC diagnostics that test the integrity of the core PC devices, such as the processor fans and cooling system
• Video and display diagnostics
• Additional hard drive diagnostics

I would request you to perform SFC scan(if you have not tried it) and then check if it helps.

System File Checker is a utility in Windows that allows users to
scan for corruptions in Windows system files and restore corrupted files.

To know about SFC and to perform a SFC Scan, please refer to the below link:

Note: Steps mentioned for Windows 8/8.1, will work fine with Windows 10.

Please revert if you still face the random hang.

Thank you.

 

random restarts

Hi,

If a Windows computer random restarts, the device usually have some damaged system components. For us to provide an accurate solution, we would need you to answer the following questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to the device before this issue occurred?
• What troubleshooting steps was already performed to your laptop?

In the meantime, it will be best to make sure that the latest update of Windows is installed on your device. If the same issue happens after installing Windows Update, we suggest running the power troubleshooter. To do so, follow these steps:

• Open the Control Panel.
• Using the search bar at the upper-right corner, type troubleshooting.
• From the search results, click on Troubleshooting and then select System and Security.
  
• Click on Power and then follow the prompts to successfully run the tool.

We are looking forward to your response.

 

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.
