Disable: Hibernation

Hibernation files represent a critical security vulnerability. An attacker with physical access can boot a live OS, copy hiberfil.sys , and perform offline memory forensics (decrypting keys, passwords). Conversely, disabling hibernation eliminates this attack vector but prevents forensic acquisition of live memory post-crash.

While modern NVMe SSDs possess high endurance ratings, the constant writing of multi-gigabyte hibernation files during each shutdown cycle adds unnecessary write amplification. For high-write environments (e.g., video editing or database servers), disabling hibernation can extend the operational lifespan of TLC and QLC NAND flash. hibernation disable
