Windows tuning with an evidence trail, not blind trust.
ProofTune measures first, explains everything, and changes only your account — every action journaled, every action reversible in one click. No admin rights. No background anything.
Six tools. Each one bounded.
No “scan & fix everything” magic. Every capability states its limits before it runs — then scroll down and try them live.
Read-only diagnostics
Seven bounded probes measure OS support, CPU, memory, storage, graphics and power state. A failing probe can never suppress the others.
Startup control with real undo
Disable sign-in apps without deleting their entries. Undo restores the exact previous approval stamp — not an approximation.
Conservative cleanup
Only your own temp files, thumbnail cache and stale crash reports older than 24 hours. Locked or in-use files are skipped — never forced.
Performance preset
Trims menu delay and UI animations for a snappier desktop. Seven documented settings, one click to apply, one click to restore Windows defaults.
Privacy preset
Advertising ID, tailored experiences and consumer suggestions — off for your account. Every key is policy-backed and restorable.
Storage insight, read-only
Finds the largest profile folders with a bounded, cancelable metadata scan — heartbeat progress, hard caps, and your disk untouched afterwards.
Click around — this is the app.
A faithful in-browser replica of the real ProofTune 0.1.0-preview.1 window. All four pages, the exact strings from the build — and yes, the toggles work.
System readiness
A clear, local view of this PC — measured without changing it.
Capability evidence
System report
One bounded result for every independent probe.
Projected capabilities
Optimization
Every action runs only when you press its button, targets only your Windows account, and is recorded with before/after state.
Startup apps
Disable keeps the entry so nothing accidentally launches at sign-in; Enable restores it. Undo returns the exact previous approval stamp.
Safe cleanup
User temporary files older than 24 hours, Explorer thumbnail cache, and queued/archived crash reports. Locked or in-use files are skipped, never forced.
Visual performance, privacy & storage insight
Performance preset trims menu delay and animations; privacy preset turns off the ad ID and consumer suggestions; restore buttons put back the documented Windows defaults. Storage is read-only.
Support & privacy
Review exactly what leaves the application before choosing a destination.
Included
Always excluded
Local-first safety
Diagnostics run locally in the non-elevated UI process. No bundle is uploaded automatically. Saving only occurs after the generated JSON is displayed for review and you explicitly choose a file destination.
Not a “PC optimizer”.
The category earned its reputation. ProofTune is built as the counter-example.
| Typical “optimizer” | ProofTune |
|---|---|
| ✗ Installs a background agent, driver or service | No drivers, no services, no scheduled tasks — a plain per-user app |
| ✗ Demands admin rights on every run | Never elevates — installs and runs without a single UAC prompt |
| ✗ Finds thousands of scary “errors” and bulk-deletes | Fixed, disclosed catalog of documented settings; keys shown up front |
| ✗ “Undo” means a system restore point, maybe | Journaled before/after state per action — restore is exact, not best-effort |
| ✗ Telemetry, upsells, “Pro” nag screens | No telemetry SDK, no beacon, and nothing to upsell — it’s a preview |
Rules the build enforces — not promises the marketing makes
Each candidate MSI passes an auditable pipeline — tests, installer database inspection, and static gates — before it’s allowed to exist.
Support bundles you can read before you share
// everything the exporter is allowed to emit — nothing more { "schema": "prooftune-support-bundle/1", "report": { "probes": 7, "failed": 0, "durationMs": 1413 }, "os": { "product": "Windows 11 Pro", "build": 26200, "support": "Supported" }, "safety": { "scope": "HKCU", "reversible": true, "userNames": "excluded", "serialNumbers": "excluded", "filePaths": "excluded" } }
Measure first. Change nothing silently.
Scan & explain
A read-only capability snapshot tells you what this PC can safely use — with plain reason codes instead of a magic health score.
Choose each action
Nothing runs on its own. Every optimization waits for an explicit click and states exactly what it will touch before it starts.
Review or undo
Every action reports before/after state. Undo restores the exact prior configuration — including the startup entries other tools just delete.
We publish what the app actually changes
Deep-dives on the exact registry keys, blobs and policies involved — verify before you ever install.
How Windows really tracks startup apps: the StartupApproved\Run blob
What Task Manager’s Disable actually writes, byte by byte — and why deleting the Run entry is the amateur move.
HKCU vs HKLM: why “runs without admin” must be a promise about scope
The two-registry-hive rule that separates safe per-user tuning from tools that quietly need SYSTEM.
Temp cleanup without fear: age filters, allowlists, and locked files
The three rules that make deleting %TEMP% content boring — and why “force delete” is a red flag.
