Reasons for System thread exception not handled BSOD Error Windows 10

The WppRecorder.sys Blue Screen issue occurs due to a service stack update in Windows 10 (and previous versions). To support devices with low disk space such as tablets, SSU runs the CBS S Identify process, which compresses some rarely used files in the c:windowsWinSxS directory. This Component-Based Service Cleanup procedure revalidates the folder as a scheduled task after you install or uninstall an update. The problem started when it also compressed some driver files (e.g. Cdrom.sys), they are hardlinked to a direct copy in the system32drivers folder. When using an NTFS volume located in a 4KB advanced format volume, the bytes that pass through the .data section of Cdrom.sys include (unfortunately) some bytes from the .pdata section. As a result, Windows crashes right in the DriverEntry process of cdrom.sys. However, you can fix the problem with some tricks –

This is how to fix WppRecorder.sys System Thread Exception not handled BSOD Error Windows 10 –

c:windowssystem32compact.exe /U c:windowssystem32drivers*.sys

  1. Restart the computer and enter the command below, then press Enter –

fsutil behavior set DisableCompression 1

  1. This will disable NTFS compression system-wide so CBS Scavenger may not cause further problems.
  2. Again restart your PC to implement the DisableCompression setting.

Now, the files will continue to be compressed but CBS Scavenger will no longer compress the file and result in a blue screen error.

2] Install Windows Update
