Disk usage
Pick a drive and click through the biggest folders and files to see where your space went. It only reads. It never deletes.
WinKit
Windows administration, without the clutter.
A free, open-source toolkit for Windows 10 and 11 that shows what your PC is doing, finds what is wrong and helps you fix it: diagnostics, disk usage, cleanup, Wi-Fi and network tools, in one portable file under 1 MB.
- Under 1 MB
- One portable file. Nothing to install.
- No account
- No telemetry, no cloud, no ads.
- Honest
- Every action is real and explained first.
- Six themes
- Dusk and Dawn by default, plus your own.
Every action WinKit takes is a real, explainable operation. No fake optimizations, no invented performance claims.
New in 2.1.0
Find the problem,
not just the symptoms.
Wi-Fi and connection test
Signal, channel, speed and security, plus a one-click test that says whether the problem is your PC, your router, your provider or DNS.
Health report
Save a plain-text summary of your PC to send to whoever is helping you. Names and addresses stay out unless you tick a box.
Hardware health
Free space for every drive and, on laptops, battery charge and how much of its original capacity is left.
Open ports
Every open port and connection with the program that owns it. See what is using port 3000 or talking to the internet.
Right-click menus
Copy, show in folder, search online and end process, right where you need them. Click an address or value to copy it.
Tour
A closer look.
Real screenshots of WinKit 2.1.0 on Windows 11.
Your PC at a glance.
Live CPU and memory, storage, GPU, network and Windows build, plus hardware health: free space on every drive and, on laptops, how much of the battery’s original capacity is left.
Ctrl + K, then type.
Jump to any page, tab or action with a few letters. Here “ports” finds the open ports list, and Enter opens it.
Where did the space go?
Pick a drive and see every folder and file sorted biggest first, with its size and share of the drive. Click a folder to look inside. It only reads, it never deletes.
11 checks, in plain language.
Storage, Windows integrity and updates, drivers, startup, services and network, each with a short explanation and a fix where one exists. On this PC: one warning, 2 GB of temporary files.
Review first. Then clean.
Each category shows its size, item count and location. The Recycle Bin is not selected unless you choose it, and nothing is removed until you confirm the total.
Find where it breaks.
Checks each step between your PC and the internet: network adapter, router, internet and name lookup, with timings, then says where the problem is.
Know what’s listening.
Every open port and connection with the program and PID that owns it. Right-click to copy an address or search the program online.
A summary you can share.
One plain-text report of your PC for whoever is helping you. Computer name, network addresses and Wi-Fi names are left out unless you tick a box.
Signal, channel and speed.
Wi-Fi details show signal, band, channel, speed and security, with plain advice when the signal is weak or the channel is crowded.
Six themes, plus Auto.
Dusk, Dawn, Midnight, Carbon, Slate and Light, or Auto to follow Windows. Edit a theme, or import and export your own.
Features
Everything Windows keeps
in a dozen different places.
System overview
CPU, memory, GPU, storage, network, Windows build and uptime in one place, with meters that change colour as they fill. Instead of Settings, Task Manager and winver.
Diagnostics
Eleven checks across connectivity, drivers, disk health, services and Windows Update, reported in plain language rather than error codes, with a one-click fix wherever one exists.
Processes & services
A live process list with real memory and CPU for every process, sorted by memory like Task Manager, plus services and startup items in the same window.
Disk usage
See what is taking your space, drive by drive and folder by folder. Junctions and cloud-only files are not counted twice, and the scan can be cancelled any time.
Network tools
Ping, traceroute, DNS lookup, IP configuration, open ports, Wi-Fi details and a connection test, next to maintenance actions like flushing DNS and resetting adapters.
Cleanup
Scan temporary files, the thumbnail and Windows Update caches and the Recycle Bin, see what each category holds, and reclaim only the space you choose to.
Administrative utilities
Installed applications with clean uninstall, an environment variables editor and a hosts file editor, elevated only when a task needs it.
Health report
One plain-text summary of your PC for a friend, a forum or a support desk. Computer name, addresses and Wi-Fi names are left out unless you include them.
Made to be used
Quick Open jumps to any page or action. Every list is searchable, values copy with a click, and the window reopens exactly where you left it.
Principles
Small, private, honest.
Small on purpose
The whole app is one executable under 1 MB. It idles at almost no CPU, and stops polling entirely while minimised.
Private by default
Settings and history stay on your machine under %LOCALAPPDATA%\WinKit. No account, no cloud sync, no telemetry. Crash reports are only sent if you press Send.
No fake optimisation
Every action is a real, explainable operation. Anything destructive asks first, and WinKit never follows a link or junction out of the folder it was asked to clean.
Keyboard
Everything is a few keys away.
- CtrlKQuick Open: jump to any page, tab or action
- CtrlFSearch the current list
- CtrlRRefresh

- CtrlBHide or show the sidebar

FAQ
Questions, answered.
Windows says the publisher is unknown. Is it safe?
WinKit is not code-signed yet, so Windows SmartScreen may show an "unknown publisher" notice the first time you run it. The source code is public on GitHub, and every download has a SHA-256 checksum you can verify below.
Does it need administrator rights?
No. It starts as a normal app. A few actions, such as resetting the network stack or editing the hosts file, ask Windows for approval when you use them. Checks that need those rights say so instead of guessing.
What does it send over the internet?
Nothing on its own, apart from an optional check for new versions against GitHub Releases, which you can turn off. There is no account and no telemetry.
Portable or installer?
The portable file runs from anywhere and leaves nothing behind. The installer adds a Start Menu shortcut and an uninstaller, and both update themselves from GitHub Releases after a checksum check.
It says WebView2 is missing.
WinKit's interface uses the Microsoft Edge WebView2 Runtime, which Windows 11 and current Windows 10 already include. If yours is missing, WinKit offers the official download link.
Where is my data stored, and how do I remove it?
Settings, themes and history live in %LOCALAPPDATA%\WinKit. Delete that folder to remove everything. The installer's uninstaller also removes the start-with-Windows entry.
Does it replace Task Manager?
It covers a lot of the same ground in a calmer window, and adds disk usage, Wi-Fi, diagnostics and a health report. It does not try to be a performance profiler.

Code signing policy
How releases are signed.
Free code signing provided by SignPath.io, certificate by SignPath Foundation.
Status: WinKit is applying to the SignPath Foundation program. Until signing is in place, releases are unsigned and Windows SmartScreen may show an "unknown publisher" notice. Every download has a SHA-256 checksum you can verify.
- What is signed. Only WinKit.exe and the installer, built from the public source code in this repository by an automated GitHub Actions build. Nothing is signed from a developer's own PC.
- Authors, reviewers and approvers. Im4Theone (project owner). Every signing request is approved by hand.
- Security. Everyone with access to the repository or to signing uses multi-factor authentication.
- Behaviour. WinKit asks before it changes the system, can be uninstalled, and does not send personal data (see the privacy policy below).
Privacy policy
WinKit does not collect your data.
WinKit has no account, no analytics and no telemetry. Settings, themes and activity history stay on your PC in %LOCALAPPDATA%\WinKit. The program does not transfer information to other systems unless you ask it to. The only network use is:
- Update check. If enabled (the default, and it can be turned off in Settings), WinKit asks api.github.com for the latest release. It sends no personal data beyond what any web request includes, such as your IP address. Downloading an update happens only when you choose it, from GitHub, and is verified with a SHA-256 checksum.
- Error reports. Only when an error occurs and you press Send. You can preview the report first. It contains an error ID, the WinKit and Windows versions, the architecture and the technical error details, and goes to a report collector run by the developer. Nothing is sent automatically.
- Network tools. Ping, traceroute and DNS lookup contact the host you type. The connection test contacts your router, 1.1.1.1 or 8.8.8.8, and example.com.
- Web view. The window uses the Microsoft Edge WebView2 Runtime that comes with Windows. WinKit loads no remote content in it, and the runtime is covered by Microsoft's own privacy statement.
The health report is saved or copied only when you ask, and leaves out your computer name, network addresses and Wi-Fi names unless you tick a box.
