Disable SysMain (Superfetch / prefetcher)

ServicesModerate riskReversible

Disables SysMain (formerly Superfetch). Helps on SSDs where prefetching adds wear without real benefit. Microsoft auto-disables this on most SSD-only systems already; tweak forces the issue.

How MaxTweaks applies this

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.
