Windows 7 hangs with AM - KB4493472 ?


Recommended Posts


i started today my old thinkpad after few months of not using it;  running Windows 7 SP1 and updated it to latest MS cumulative patch KB4493472

I'm running AE & AM - 1.1.196 beta on Veracrypt 1.23-hotfix2 full disk encrypted boot partition.

I noticed during disk intensive operations (e.g. Passmark Performace Test - particularly Disk Mark) the computer hangs. Not whole at once, but first the HDD LED goes off and apps start to hang one by one. It looks like apps which need disk access hang (e.g. web browser) and simple app like calculator continues to work. At the end i need to power off the laptop. In the windows system eventlog there is absolutely no related event saved. The SSD shows no hw errors.

If i disable the anti-ransomware the hang situation does not seem to happen and before the months i was using the computer regularly it did not happen as well (with AR enabled).

As the AM version is same, maybe it might be related to some recent windows patch

I have no Sophos nor Avast nor any other antivirus installed (re known issues with this KB4493472: Microsoft and Sophos have identified an issue on devices with Sophos Endpoint Protection installed and managed by either Sophos Central or Sophos Enterprise Console (SEC) that may cause the system to freeze or hang upon restart after installing this update. )

I do not experience such issues on my other laptop running Windows 10 1803.

Anyone with similar problem or some advice how to solve this issue?

Maybe this MS patch affects Malwarebytes in a similar way like Sophos?
