Problema

The Windows crash dump file (memory.dmp) is a vital piece of evidence that allows support to find the root cause of a system crash. Sometimes the Windows dump file can't be located after a blue screen error on systems where FRP is installed.

Causa

FRP is encrypting the Windows pagefile.sys. When a system restarts after a system crash dump, the pagefile is re-encrypted. This design makes it impossible to generate or copy the memory dump to the memory.dmp file.

Soluzione

This behavior is expected, because of the Windows page file encryption by FRP.

Directly after a blue screen error, restart your computer in Windows Safe Mode without networking.

The above option causes Windows to start without the FRP driver. Windows is now able to copy the pagefile to memory.dmp.
Restart Windows normally and obtain the newly created dump file.
