MEET YOUR TOOLKIT

Fix what’s wrong.
Tune what works.

Two ways in. Fix my PC finds problems and fixes them safely. Tune my PC sets your PC up for what you do today, and changes only what you approve.

FIX MY PC

Something not working? Scan Windows, read what’s wrong in plain language, and approve each repair.

START HERE

Scan my PC

One read-only scan across Windows, storage, devices, security, app crashes, network link speed and clock sync. Nothing changes until you approve a repair, nothing is uploaded, and each scan is saved so you can compare later.

A CLEAR RECORD

TUNE MY PC

Want more from your PC? Say what you want today, review Hanki’s plan, and apply only what you approve.

START HERE

Tune my PC

Choose Gaming + Performance, Gaming + Quality, Creative work or Low power. Hanki reads your display, Windows, mouse, graphics driver, processor, memory and storage settings, then shows a plan.

Every change, before and after

You pick which changes to apply. Each is saved in Recovery first, and the steps only you can take are listed too.

Launch and measure

Start a game from your list, play for two minutes, and compare with the last run and what changed in between.

Gaming

Windows and driver settings for smoother play.

Refresh rate, GPU choice and Game Mode
NVIDIA and AMD Radeon settings, with presets
Overlays, recorders and busy background apps

SMOOTHER PLAY

Fair before-and-after comparisons

EVIDENCE, NOT GUESSES

No placebo tweaks.

Hanki won’t disable Defender, change timers or boot settings, switch off services in bulk or purge memory for a few frames. It explains why, and says so when no change is the right answer.

How Hanki decides

A second pair of eyes, when you need it.

The optional Assistant helps prepare logs and reports. Review what you share before sending it to OpenAI with your own API key.

Read about privacy

Help from someone you trust.

Hanki opens Windows' own Quick Assist, so a friend or your IT person can see your screen or lend a hand, after a clear scam warning. Hanki doesn't join or record the session.

About Quick Assist

SEE IT IN ACTION

Real screens.
Plain answers.

Screenshots are from Hanki Tools 0.20.0. Each result comes with a clear status and a next step; the technical details stay one click away.

Hanki Tools home screen: a search box, the Fix my PC and Tune my PC cards, and six tiles about this PC — **Home.** Search in your own words, or start with Fix my PC or Tune my PC. Your PC at a glance sits below.

Fix my PC: the scan card with the last scan result, and tiles for Full scan, Diagnose, Maintain, Shield, Connect and Recovery — **Fix my PC.** Scan Windows in one read-only pass, see how the last scan went, and open the tool for the details.

Guided checks for a PC that restarted by itself: five ordered steps, each with a button that opens the right tool — **Guided checks.** Pick what's happening, such as a restart or a blue screen, and follow steps that open the right tool.

Windows Update check: Windows Update is working, the last update installed two days ago, no updates failed, and a few driver updates will be retried — **Windows Update.** When updates last installed, what failed and why, in plain language. Defender's daily definition updates can't hide a broken Windows Update.

Connect: guided troubleshooting checks the connection and suggests one next step — **Connect.** Check the connection, try one suggested step, then confirm whether it helped. Detailed checks for the adapter, router, DNS and the internet are a tab away.

Shield Defender audit: protections reported as on, the security intelligence version and exclusions that need administrator access — **Shield.** What Microsoft Defender reports, explained, including what Hanki can't see without administrator rights.

Tune my PC: choose Gaming, Creative work or Low power, then scan to see a plan before anything changes — **Tune my PC.** Choose what you want today, then Hanki reads your settings and shows a plan. Every change is reviewed before it is applied.

Gaming: your games, NVIDIA and AMD Radeon settings and Tactical Vision — **Gaming.** Your games, NVIDIA and AMD Radeon settings, and per-game Tactical Vision, each reviewed before it changes.

Memory health: 16 GB DDR4 in two slots, a note that memory ran short earlier since the last restart, and a system-managed pagefile — **Memory.** Installed memory, its speed, headroom and pagefile, and why memory cleaners don't help.

SMALL TOOLKIT. FINNISH SPIRIT.

BUILT WITH A LITTLE SISU

Your PC.
Still your decisions.

Useful tools should help you understand what is happening—and what happens next.

Sisu is Finnish for grit: the quiet determination to keep going.

01 /

See before you change.

Start with read-only diagnostics. Review supported actions before you run them.

02 /

Know the limits.

No guaranteed speed gains or one-click miracle fixes. Hanki’s experimental scanner is not a replacement for antivirus protection.

03 /

Look under the hood.

The source is available on GitHub under the PolyForm Noncommercial license. Read the code, follow changes or report an issue.

COMMON QUESTIONS

A few things worth knowing.

For planned Pro and Technician extras, see editions and availability.

What does Hanki Tools do?

Hanki Community is a Windows 11 toolkit, free for noncommercial use, for reading diagnostic evidence, investigating crashes or slowdowns, reviewing startup and storage, and choosing supported repairs or tuning changes.

Is Hanki Tools free?

Yes. Hanki Community is free for noncommercial use, including its current diagnostic and manual tools. Hanki Pro and Technician are planned paid editions for additional automation and convenience; they are not on sale yet. Existing Community features stay free.

Will a scan change my Windows settings?

The diagnostic checks do not apply repairs or tuning changes. Hanki can save scan history locally. Supported repairs and tuning actions show what will change and require your approval.

Which Windows versions are supported?

The current download targets 64-bit Windows 11. Check the latest release notes for the precise build requirements and any platform changes.

Which problems can Hanki help investigate?

Hanki organizes evidence for unexpected restarts, freezes, slow performance, startup items, storage, network connections, and Microsoft Defender status. A finding is a lead to investigate, not a guaranteed diagnosis.

What does Tune my PC do?

Tune my PC reviews relevant settings and prepares profiles for gaming, creative work, or lower power use. Review the proposed steps before applying them. Recovery records supported changes; not every Windows action can be undone.

Last known · Windows 11 · x64 · code-signed

Last known release: 0.20.0 · published October 9, 2026

Release details update from GitHub. Until then, verify the last-known version and matching asset before installing.

Check the current release notes for build checks, requirements and any Windows testing still pending.

Release notes and downloads · Portable ZIP SHA-256 ·

HankiTools.exe and the setup program are code-signed (Iikka Amos Isosaari). Windows SmartScreen may still warn until the publisher has built reputation; see what to expect. Check the current release’s signature status and verify its SHA-256 checksum before running the download.

Prefer the command line? Install with Scoop, which checks the checksum for you:

scoop bucket add hanki https://github.com/hankitools/scoop-bucket
scoop install hanki/hanki-tools

Code signing policy What’s changed Testing checklist Test builds

READ FIRST

Before you install.

Windows version: builds target 64-bit Windows 11; ARM64, Windows Server and older Windows releases aren’t certified by this app. Check the current release notes for exact build requirements.
Signing status: unsigned preview builds may trigger Windows SmartScreen before the first run, and the current stable release is not code-signed yet either — see the code signing policy and always compare the published SHA-256 checksum first.
Installer choice: the Windows setup installs for just your account under %LOCALAPPDATA%\Programs (no administrator approval) or for all users under Program Files (administrator approval required). The portable ZIP needs neither.
Updates are manual: Hanki does not update itself. Run the newer setup in the same install scope, or extract a new portable ZIP, when you want to update.
Your data and uninstalling: scan history, recovery data and settings backups live in %LOCALAPPDATA%\IgezziGuard. Uninstalling or deleting the app removes only the application files, not that folder; remove it yourself for a full clean-up.

TRUST

Code signing policy

Windows releases are intended to be signed through the SignPath Foundation program; the application is pending. Current releases are not code-signed yet.

Team roles: committers, reviewers and approvers — @hankitools. Only builds made by GitHub Actions from the public repository are submitted for signing, and an approver reviews every signing request.

Privacy: this program will not transfer any information to other networked systems unless specifically requested by the user or the person installing or operating it. See the privacy policy and the full code signing policy.
