Optimizer — the Swiss Army Knife for Windows Customization

Does it feel familiar when, after a fresh Windows installation, the system somehow doesn't run as fast as you'd like? Or are you annoyed by intrusive telemetry and automatic updates? This is exactly what Optimizer solves — a universal tool for fine-tuning Windows, which has gathered over 16 thousand stars on GitHub.

What is Optimizer?

Optimizer is a free open-source utility written in C#. It provides a convenient graphical interface for performing dozens of Windows optimization and customization operations. The project has been actively developing since 2017 and supports all current versions of Windows, including Windows 11.

By the way, the application is translated into 24 languages, including Russian — thanks to contributor mrkaban for the localization!

Top 5 Features That Will Surprise You

1. Deep Privacy Cleanup — with one click, it disables Windows and Office telemetry, Cortana, automatic updates, and even CoPilot AI in Windows 11.
2. Performance Optimization — allows you to disable unnecessary services, manage startup items, clean the disk, and even configure hardware parameters like HPET.
3. Network Tools — change DNS, check ping, search IP in SHODAN.io, and even edit the hosts file.
4. Application Management — bulk removal of UWP apps and quick installation of popular utilities.
5. Automation — command-line support and templates for automatic configuration.

Technical Features

Optimizer is written in C# and requires .NET Framework 4.8.1. Interestingly, to run it on server versions of Windows, you need to use a special flag /unsafe. The project architecture is designed to make adding new features and translations as straightforward as possible.

An interesting fact: the developer even included the ability to disable Windows Defender through special launch parameters.

When is Optimizer Particularly Useful?

• After a fresh Windows installation — to quickly configure the system to your needs
• For "reviving" old computers — disabling unnecessary services can provide a noticeable performance boost
• For privacy concerns — when you need to reliably disable Microsoft data collection
• For system administrators — bulk configurations and automation save hours of work
