Sets AdditionalDelayedWorkerThreads = 8 under Session Manager\Executive. Companion to the critical-workers tweak: this raises the *delayed* worker pool, which handles lower-priority asynchronous kernel work like file-system metadata maintenance, NTFS log writes, and certain registry hive operations. Lifts a quiet ceiling that limits sustained I/O on dense workloads. Cheap, low risk. Reboot required.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
