When the windows driver verifier was used all non-Microsoft drivers were checked and all Microsoft drivers were unchecked.
Every computer displayed an immediate blue screen.
The stop codes were:
driver verifier detected violation (alone, or no additional information provided about the violation)
driver verifier detected violation hpdskflt.sys
driver verifier detected violation sddtoki.sys
driver verifier detected violation soluto.sys
all of the above were on the driver list except sddtoki.sys
Some of the computers that produced blue screens with driver verifier did not update the mimidump or memory.dmp files
The sytem defaults were changed to see if this could more frequently record the blue screens. In startup and recovery settings small memory dump (256) was changed to automatic memory dump. Automatically restart was unchecked. The dump file was not changed and remained %systemroot%\memory.dmp.
Even with the above changes many of the driver verifier produced blue screens were not showing up in the memory.dmp file.
A few of the computers had whocrashed which provided additional information about the windows driver verifier stop code driver verifier detected violation that had no additional information. For this one whocrashed processed c:\windows\mindump and found cvirtualdrive.sys
For this problematic driver I could uninstall and reinstall cyberlink. The problem is that I cannot rerun windows driver verifier to see if there is a third driver on this computer or any additional drivers that need to be fixed. This computer and all the other computers had the windows defender offline scan. Using the windows driver verifier after using windows defender offline likely will go into the blue screen/windows defender offline loop and make the computer unusable.
There was some information about paging files and minidump or memory.dmp files that I did not understand. The computers have 8 to 32 gb of ram. The paging file size on the computers viewed varies from 1024 to 4864. The default settings have never been changed. Is this something that needs to be manually changed to increase the probability that minidump and memory.dmp files will be updated for each blue screen? If so what are the steps?
The computer in the initial post, the first computer is now in the Microsoft store. There were three restore points and none of them work. They were able to get to the restore points only by using a usb drive with windows iso. They said that they would save the files and reinstall the windows 10 professional operating system, drivers, files, office, etc
It appears that other people have been having problems with windows defender offline. This one was on Microsoftanswers:
Windows 10 Defender Offline stuck in infinite restart loop - Microsoft Community
The second computer that is stuck in the windows driver verifier/windows defender offline incompatible loop has no important files. I have a windows 10 professional recovery disk and can insert it into the optical drive.
For all of the other computers I could attempt to fix the blue screen stop codes by deleting drivers. The problem is that I cannot check to see if it was effective as running windows driver verifier again is likely to put the computers into the incompatibility loop. The first computer above had three restore points that were created within one week of the incompatibility loop and none of them worked.
I wonder whether temporarily turning off windows defender may prevent the incompatibility loop?
If not I am seeking other options to be able to get back to a working computer.
