🚀 tiny11 25H2 Review: Lightweight Windows 11 for Old PCs

Discover tiny11 25H2, a streamlined Windows 11 build by NTDEV. Skip Microsoft account, bypass TPM, and run Win11 on legacy hardware with just 2GB RAM.

🔍 What is tiny11 25H2?

tiny11 is a Windows 11 debloating project maintained by Romanian independent developer NTDEV. tiny11 25H2 is built upon Microsoft's official Windows 11 25H2 release from September 2025. It is not a "cracked" version of Windows, but a legitimate slimmed-down system created through official Microsoft tools, removing a large number of unnecessary components while retaining core functionality.

The biggest difference from the official system is that tiny11 25H2 requires no Microsoft account to install and use, bypasses TPM 2.0 and Secure Boot hardware restrictions, allowing nearly any PC capable of running Windows 10 to install Windows 11.

✨ Features: More Than Just Lightweight

💾 Extreme Resource Efficiency

The biggest highlight of tiny11 25H2 is its extremely low resource requirements. After installation, the C drive occupies only around 10GB, and memory requirements are reduced to 2GB. The more streamlined tiny11core version takes up only around 5GB on the C drive, with memory usage of just a few hundred MB, making it a lifesaver for legacy devices.

🗑️ Thorough Cleanup of Pre-installed Apps

tiny11 removes most Microsoft pre-installed apps, including:

• Microsoft Edge browser (completely removed)
• OneDrive, Xbox-related apps
• Mail, Calendar, Weather, News and other modern apps
• Clipchamp, Solitaire and other extra software

🔒 Privacy and Experience Optimization

• Disable Microsoft telemetry data collection
• Disable advertising data collection
• Retain basic tools such as Calculator, Notepad, Paint, and Terminal

📊 Two Versions: How to Choose?

tiny11 25H2 offers two versions to meet different user needs:

Regular users are recommended to choose the standard version, because it retains maintainability; while the core version is more suitable for technical users, testers, or virtual machine environments.

🛠️ Usage Experience and Tips

🇨🇳 Chinese Language Support

The official tiny11 25H2 defaults to an English interface, but Chinese language support can be added. Specific methods are as follows:

• Install Chinese language pack via PowerShell:

Install-Language zh-CN

• Set global Chinese display:

Set-WinUserLanguageList zh-Hans-CN -Force

or

Set-SystemPreferredUILanguage -Language zh-CN

• Restart the system to apply changes.

If you encounter language pack installation errors (such as 0x80073D01), you may need to modify Windows Update policies or temporarily disable the firewall.

For users seeking a perfect Chinese display experience, community-made Chinese versions of tiny11 are also available, with Chinese support directly integrated and no extra language pack installation required.

⚠️ Usage Notes

• 🔑 Activation Required: tiny11 is still a Windows system and requires a legitimate license for activation
• 💻 Software Compatibility: The vast majority of daily software runs normally, including browsers, office software, etc.
• 🎮 Gaming Support: Core components like DirectX are retained, game performance is unaffected
• 🔧 Driver Compatibility: Compatible with official Windows 11 drivers, no special requirements
