PC Tweaker brings Windows tuning, Audio diagnostics, hardware monitoring and maintenance into one review workflow for Windows 10/11 x64. Inspect a finding, understand the trade-offs and choose individual supported changes.

Audio: the details behind Windows sound

See playback and recording devices, formats, effects, spatial sound and Equalizer APO status. Findings can point to a Bluetooth headset in call mode, a muted microphone or an inactive APO registration. Review the specific result before choosing a supported action.

A read-only 10-second DPC/ISR trace helps identify drivers worth investigating under your workload. It requires administrator permission. A driver appearing in the trace does not prove the cause of an audio problem.

Inspect before applying

Scan 2.0 groups configuration and maintenance findings before you select fixes. The read-only hardware audit can show RAM speed, PCIe link and Resizable BAR findings when Windows exposes the data; it does not change firmware. Proof of change compares before-and-after measurements for supported actions and can report no measurable difference. A configuration score is not an FPS benchmark.

48 Free controls. 36 optional Pro controls.

Free works without an account or card. Optional paid Pro adds advanced workflows such as Game Sessions and registry cleanup. Registry discovery is free; cleanup is Pro and saves a .reg backup. Registry cleaning is housekeeping, not a promised speed upgrade. Current plans and conditions are on the official website.

Recovery has limits

History and restoration cover supported settings and their recorded previous values. Restoring a setting does not recover permanently deleted caches, reinstall removed applications or replace a full backup. Cleanup, repair and driver operations have separate recovery limits. Results depend on Windows, hardware, drivers and workload.

Current release: 1.20.2

About the gallery

The three 1.20.0 interface previews were captured from the official demo on 3 November 2026, in Pro view, and remain visibly labelled sample data. Devices, findings and history entries are synthetic examples, not native PC measurements or evidence of a performance gain.
