Even when configured correctly, Windows 11 may fail to produce minidumps. Common causes:
| Issue | Explanation | Solution | |-------|-------------|----------| | | Dump requires paging file on boot volume at least 200MB + RAM size. | Set paging file to System managed or min 800MB. | | Secure Boot + TPM restrictions | Windows 11's security may block kernel writes after crash. | Temporarily disable Secure Boot for testing. | | Disk space | If C:\ is full, no dump is written. | Free up space (at least 2GB). | | Automatic restart | System reboots before dump completes. | In Startup/Recovery, uncheck Automatically restart . | | Storage driver | NVMe/RAID drivers may fail to write dump. | Update storage drivers or switch to AHCI mode. | | Windows Error Reporting (WER) cleanup | WER task \Microsoft\Windows\WER\ReportQueueCleanup may delete old dumps. | Check Task Scheduler → increase retention period. |
