Performance checks

SpeedCheck brings together measurements and Windows settings that can affect responsiveness.

Essential checks​

  • System drive type: identifies whether Windows is on an SSD or an HDD.
  • Free disk space: assesses the available space on the volumes; the check uses a threshold of 20% or 50 GB of free space.
  • Available memory: looks for at least 20% available RAM in the current snapshot.
  • Startup programs: counts startup entries, including disabled ones, and can open Task Manager for review.
  • Windows patch status: examines the installed Windows state; the check for pending updates is available on demand.

System and resources​

The tool examines the power plan, busy processes, memory-slot information, uptime, signs of a pending restart and Fast Startup. Process information is a snapshot: review an unfamiliar process before deciding what to do in Windows.

Boot measurements come from the Diagnostics-Performance event log of Windows. If no suitable events are available, no boot time can be derived from them.

Storage and Windows options​

Further checks cover TRIM, the drive-optimization schedule, temporary files, Storage Sense, visual effects, graphics options, core isolation, search indexing and background apps. Many are informational and lead to the relevant Windows settings page.

The temporary-files finding measures cleanup candidates; SpeedCheck does not clean them itself. Likewise, an app-update finding does not mean that SpeedCheck has installed those updates.
