Bug check 0x00000044 (MULTIPLE_IRP_COMPLETE_REQUESTS) means a driver tried to complete an I/O Request Packet that was already completed. This is always a driver bug — the driver has faulty reference counting or completion logic. Common culprits: storage drivers (especially third-party RAID or NVMe drivers), antivirus file system filter drivers (they intercept all file I/O), and disk encryption drivers (BitLocker rarely, but third-party encryption often). Fixes:
- Check the minidump for the faulting driver name,
- Update or remove the identified driver,
- If it's an antivirus driver: uninstall the antivirus completely and test with Windows Defender,
- Update storage controller drivers from the motherboard manufacturer,
- If using third-party disk encryption: update it or temporarily disable.
