First Touch

Sit Down at the Machine — Know What's Wrong in Under a Minute

TuneBit scans eight subsystems automatically on launch and surfaces the offending pieces in a single dashboard. No flipping between Event Viewer, Task Manager, MMC snap-ins, and a dozen Sysinternals utilities.

Eight-Subsystem Triage Scan

Health, temp/junk, security posture, disk capacity & SMART, privacy/telemetry, OEM bloatware, performance counters, and registry hygiene — all surfaced on the first launch wizard before you've poured the coffee.

Runs automatically on first launch

Single Pane of Glass

A 0–100 health score plus status cards for the things that actually fail in the field — disk pressure, security gaps, privacy/telemetry exposure, and bloat. Quick actions remediate without opening another window.

Always available from the Home screen
The Toolkit

Thirty-Five Tools You'd Otherwise Carry Separately

Repair, debloat, harden, profile, and inventory — from the same binary, on every customer machine, without dragging a folder of one-off freeware behind you.

Deep Repair Suite

SFC/DISM orchestration, Windows Update repair, shell rebuilds, service restoration, BSOD minidump triage, registry recovery, file unlocker, and stuck-update fixes — the recurring tickets, scripted into one panel.

See repair tools

Hardening & Telemetry Lockdown

Disable Windows telemetry endpoints, scrub OEM bloat, kick non-essential processes off boot, and apply privacy baselines — the deployment hardening you'd otherwise hand-roll across O&O ShutUp, BloatyNosy, and a stack of registry tweaks.

See hardening tools

Performance Profiling & Tuning

Startup-impact analysis, CPU affinity watcher, scheduled-task auditing, junk & duplicate cleanup, disk optimization — quantifiable wins you can hand a customer with the invoice.

See performance tools

Diagnostics & Reporting

Event Log triage, BSOD minidump decoder, system report export, VirusTotal hash lookups, and a structured health report you can drop straight into a ticket or hand to a customer.

See diagnostic tools

Hardware Inventory & Forensics

CPU, RAM, drives (with SMART), GPU, battery wear, BIOS/firmware, network adapters — everything you'd otherwise pull from msinfo32, dxdiag, smartctl, and powercfg, in one exportable report.

See hardware tools

Active Defense Modules

Software Restriction Policy ransomware shield, shadow-copy tamper detection, rogue-process killer, honeypot canaries, and a configurable security baseline — for the customers whose recovery time you don't want to bill against.

See protection tools

Health Score for Tickets & QBRs

A weighted 0–100 score across health, security, performance, privacy, and bloat. Run it on intake, again at handoff, and you have a defensible before/after for the work order.

Why TuneBit

Engineered for Field Work, Not Shelf Life

The consumer "PC fixer" market is a graveyard of bundled adware and abandoned 2015-era utilities. The pro alternative is a folder of single-purpose tools you carry around manually. TuneBit replaces both.

Genuinely Portable

A single sub-5MB executable. No installer, no MSI, no .NET prerequisites the user doesn't already have. Drop it on a tech USB stick and it runs on any Win 8.1+ machine you plug into.

Zero Telemetry, Period

No analytics, no crash reports, no usage tracking. The only outbound call is the periodic license validation against tunebit.app. Customer data stays on the customer's machine — relevant when you're under SOC 2 or you're the contracted IT for someone who is.

No Bundled Garbage

No browser extensions, no bundled "PC optimizer" partners, no toolbar offers, no upsell nags during a customer engagement. The kind of thing you can't quietly run on a customer's machine if it shows.

First-Party C# Codebase

.NET Framework 4.8, written in-house, code-signed via Azure Trusted Signing on every release. No upstream OSS rot, no abandoned dependencies, no bundled forked GPL utilities triggering license review.

Per-Tech Pricing That Scales

Technician seats are USB-bound, not seat-of-machine. $29.95/yr covers an unlimited number of customer endpoints from one stick. One seat per tech, not per device touched.

Built by a Working Tech

TuneBit's roadmap is the author's own bench backlog. Every feature shipped because a real customer machine needed it — not because of A/B testing on a marketing landing page.

Who It's For

If You Bill By the Ticket, This Pays For Itself in One Job

TuneBit is the toolkit you'd build yourself if you had a couple weekends free — consolidated, signed, supported, and licensed by the technician.

MSPs & Field Techs

USB-bound license, unlimited customer endpoints. Plug into the customer's machine, run intake triage, fix what fixes, hand them a health report. Walk out with the stick — no residue, no leftover install.

See the field workflow

Internal IT & Helpdesks

Bench imaging cleanup, OEM debloat on first deployment, BSOD triage, scheduled maintenance via the headless command-line modes. One tool the helpdesk knows; one report format that lands in your ticketing system.

See the feature catalog

Repair Shops & Refurbishers

Standardize intake-to-handoff: scan, score, fix, score again, print. Same workflow on every machine, junior techs included. Tightens turnaround time and gives the customer a defensible "before/after" health score.

See all use cases

Independent Power Users

You're the family helpdesk and you maintain a personal fleet. Five-PC plan covers your kit; Technician plan covers everyone you keep limping along. Same tool, no consumer-product compromises.
