Software & utilities
Everything here is my own work for 64-bit Windows. Most tools target Windows 10 and 11; each one states what it runs on. Every build lists its version, size and checksum.
Nothing like that here yet. Try another term.
Rules I stick to
Zero telemetry
The apps never phone home. What happens on your machine stays on your machine.
Portable by default
No installer, no registry writes. Unpack onto a USB stick and take it with you.
Open formats
Readable JSON/INI config, CSV export. Nothing locks you in.
Long support
Fixes and security patches for older releases too. Nothing gets dropped after a year.
Verifiable builds
Every file ships with a SHA-256 computed on the server, so you can verify what you run.

Frequently asked
Is the software really free?
Yes. Every tool is free for personal and commercial use.
Why is the software free?
Because I enjoy making it. The tools come out of my own needs, and then there is no reason not to share them. If one of them helped you, I would be glad for a coffee. It is entirely optional and changes nothing about the software: everything stays free.
Why does Windows show a SmartScreen warning?
SmartScreen reports an unknown file, not a virus it found. The applications here are not digitally signed, so they have no reputation with Microsoft. Always check the SHA-256 listed with the download — if it matches, you have exactly the file I released. The Is MHSW safe? page explains it in full.
Do you collect any data?
No. The apps have no analytics and no background auto-updates. This site runs without third-party cookies.
Will there be Linux or macOS builds?
No. I build exclusively for Windows. I would rather know one system properly than three by halves — that is what lets the tools call Win32 directly and stay small and fast. Most of them target Windows 10 and 11; where it makes sense they also run on older versions.
Can I report a bug or suggest a feature?
Please do. Write to info@mhsw.net with the app version and a short description of the steps.
Who is behind MHSW
Marian Hudec - a software engineer and developer based in the Czech Republic. Alongside my own applications I work in hardware and software service — and that everyday practice is exactly where the tools you find here come from.
Software development
Native applications and utilities for Windows. From the first idea to a finished build with a checksum you can verify yourself.
Hardware service
Diagnostics, repairs and upgrades of desktops, laptops and peripherals. Bench experience, not textbook theory.
Software service
System installation and maintenance, data recovery, troubleshooting Windows, networks and printers.
A question about one of the tools, or a service problem to solve? Write to info@mhsw.net.
Missing a utility?
Tell me what you need on Windows. A lot of the tools here started exactly like that — from one specific problem.
