Iolo System Mechanic, one of the best windows optimizer for windows 10 as far as I know.

Best for: Users who want an "always-on" automatic optimizer that learns from system behavior.

Iolo System Mechanic is a veteran in the PC optimization space, and its Windows 10 version is exceptionally robust. Its hallmark feature is ActiveCare – a set of automated maintenance routines that run in the background when the PC is idle. It performs real-time registry defragmentation, removes junk files, updates drivers, and adjusts internet settings for faster browsing. System Mechanic also includes a LiveBoost module that reallocates CPU, RAM, and disk resources to the foreground application (e.g., games or video editors) on the fly.

Why it’s great for Windows 10:

  • Extremely low false-positive rate for registry issues.
  • Includes a genuine driver updater (many competitors only claim to update drivers).
  • Crush & Corral feature prevents bloatware and unwanted startup items from re-enabling.
  • Provides detailed performance graphs and logs for power users.
