← How it works

Module · Repair agent

The repair agent, in depth.

This is Fixato's core: you describe a problem in plain words, and the agent investigates your PC the way a good technician would — then fixes the real cause under your supervision. Below is exactly what it reads, what it repairs, and the tools behind each step. Skim the plain-language lines, or open the under-the-hood detail.

In plain language

You tell Fixato what's wrong — “my PC freezes and restarts,” “it's slow,” “Wi-Fi keeps dropping.” It runs a deep, read-only check, explains what it found, and proposes a fix. Nothing changes until you say yes.

Under the hood

A closed set of named diagnostic tools runs first (read-only). The agent reasons over the combined results, then maps the cause to a specific repair from its whitelist — never a free-form command.

Step 1 — Diagnosis (read-only)

It reads Windows' real logs.

Where a cleaner glances at two or three counters, Fixato opens the Event Log, correlates crashes over time, and spots the signature that keeps repeating.

  • Timestamped events, pulled from the real logs.
  • Automatic grouping by signature and time window.
  • Reasoning, not just a list: what the pattern means.

  • Jul 15 · 11:31:02Blue screen (BSOD)
    BugCheck 0x139

Three of four events cluster within 38 minutes, all with the same 0x139 stop code. That signature points to hardware instability under load, not software.

The complete read

Every check, before it touches anything.

Diagnosis changes nothing. These checks just read your system so the agent can reason about the real cause.

Crash history

It reads Windows' own record of every unexpected shutdown and blue screen, then looks for a pattern — several crashes with the same signature aren't a coincidence.

Named toolsread_crash_historyget_reliability_history

Your exact hardware

It identifies your processor down to the model and stepping, and reads the firmware revision actually installed — the detail that reveals a known manufacturer defect.

Named toolsget_system_infoget_cpu_microcode

Disk health

It checks whether your drives are physically healthy, so you know if your files are at risk before anything else.

Named toolsget_disk_healthget_smart_details

System file integrity

It checks whether Windows' own core files are intact — corruption here causes freezes and random errors. Both of these only look; neither repairs anything.

Drivers, services, updates

It spots drivers that are actually failing (not just "outdated"), stopped services, and updates that never finished installing.

The known-defect directory

It looks your exact component up in Fixato's own curated directory of acknowledged manufacturer defects and recalls. That's the step that turns a stop code into a named cause — and sometimes into a warranty claim.

The edge

It connects a crash to a real, named cause.

This is what sets Fixato apart from a “cleaner.” A repeating signature isn't random. In one real session, a cluster of 0x139 stops on an Intel Core i9-14900KF matched a manufacturer-acknowledged instability defect — so Fixato named it and pointed to the real fix.

  • The exact model and installed microcode, read from firmware.
  • The recommended microcode (a BIOS update) that corrects it.
  • The extended 5-year warranty — a remedy no fake optimizer would ever mention, because it can't be billed.

Step 2 — What it repairs (with your yes)

Then it fixes the cause — supervised.

Nothing below runs until you confirm it, and each of these repairs creates a system restore point before it changes anything. Each is a specific, audited action — not an open door to your system. The last card isn't a repair at all: it's Fixato walking you through something only you can do.

Repair corrupted Windows files

Rebuilds the damaged core files that cause freezes, crashes and errors that won't go away.

Named toolsrun_sfc_scannowrestore_health_dism

Update a driver that's actually failing

Installs the signed driver Windows Update offers for a device Windows reports as in error — never a downgrade, never a generic driver in place of your manufacturer's.

Named toolupdate_drivers

Reset the network stack

Fixes a connection that drops or won't come back by rebuilding the parts of Windows that handle networking.

Named toolreset_network_stack

Unstick Windows Update

Clears the update components that jam when a download half-finishes, so the updates you're missing can install.

Named toolreset_windows_update

Guide a firmware fix it can't automate

When the real fix is a BIOS or microcode update, or a warranty claim, Fixato names it and walks you through it. It does not flash your firmware — nobody should let software do that unattended, and we don't build the tool that would.

Every repair is reversible.

A restore point is created before any change (or the repair is blocked), you approve each action, and everything is logged on your machine. See the full picture on security & safety.
