Introduction
Hi everyone!

I'd like to introduce UnlockTool, an open-source Windows utility that I've been developing.

The idea behind the project is simple: create a convenient desktop application that brings several Windows system management and maintenance tools together in one place.

I wanted to build something practical while exploring C++, the Win32 API, and the internals of the Windows operating system.
Why did I start this project?
I enjoy experimenting with Windows, exploring how its components work, and developing software.

I decided to combine these interests into one project.

Rather than building another web-based application, I chose native Windows technologies. This gave me more control over the interface and allowed me to work directly with Windows APIs.
Technologies
UnlockTool is built using:

C++ — the main programming language.
Win32 API — native Windows application development.
GDI+ — rendering the graphical interface.
Visual Studio — development environment. Features
Process Manager Manage running Windows processes through a dedicated interface.

It provides a centralized place to inspect and manage active processes.

User Management View and manage local Windows user accounts.

This section brings basic account management functionality into the application.

Registry Tools Inspect important Windows registry parameters and access available repair functionality.

The goal is to make troubleshooting selected Windows configuration settings more convenient.

System Cleanup Clean supported temporary and cached system data, including thumbnail cache.

This helps remove unnecessary files and maintain the system.

Multilingual Interface UnlockTool supports two interface languages:
Russian
English The language can be changed directly in the application.
Native Windows Interface The application uses a custom graphical interface built with Win32 API and GDI+.

It is designed as a desktop utility rather than a web application.
What's next?
UnlockTool is an evolving project. I have several ideas for future releases:

Startup Manager
IFEO configuration inspection
System Recovery tools
Disk Manager
BSOD Monitor
Additional cleanup options
More Windows troubleshooting features These are planned improvements and may change during development. Open Source I want UnlockTool to remain an open-source project.

You can explore the source code, follow development, and keep track of future updates.

Feedback
I'm still developing and improving UnlockTool, so feedback is welcome!

If you're interested in Windows development, C++, Win32 API, or open-source software, I'd be glad to hear your thoughts.

Thanks for reading!
