Ultimate Feature Update Blocker

The Ultimate Feature Update Blocker is an advanced PowerShell script designed to lock a Windows 11 system to a specific feature update version (currently hardcoded to 23H2). It performs a deep reset of local Group Policy to resolve conflicts and then applies specific registry settings to prevent the installation of newer feature updates and Windows Insider Preview builds.

This is an advanced tool for taking firm control over your Windows Update behavior. Use with caution.

🕰️ Prerequisites

To run this script, you will need:

Administrator Privileges: The script must be run as an administrator to modify system policies and the registry.

💽 Installation & Execution

Download: Download the Feature_Update_Blocker.PS1 script file.
Unblock: Right-click the file, go to Properties, and click Unblock if the file was downloaded from the internet.
Run as Administrator: You must run this script from a PowerShell console that has been opened with administrator privileges.

🚀 Usage

The script is fully automated. When run as an administrator, it will perform the following actions:

Reset Local Group Policy: Forcefully clears the local Group Policy cache to remove any lingering or conflicting settings.
Block Insider Builds: Sets registry keys to opt the machine out of telemetry and experimentation required for Insider builds.
Apply Target Version: Sets the TargetReleaseVersionInfo and related registry keys to instruct Windows Update to target version 23H2 and no newer feature updates.
Apply Secondary Blocker: Sets an additional registry key to block feature updates as a redundant measure.

The script provides detailed output in the console window as it performs each step.

✨ Key Features

Deep Policy Reset: Clears the local Group Policy cache to resolve stubborn or "tattooed" policy settings that may interfere with update behavior.
Targeted Version Locking: Pins the operating system to a specific feature update (e.g., 23H2) using official policy settings.
Insider Build Prevention: Modifies registry settings to prevent the system from being offered Insider Preview builds.
Automated Operation: Runs from start to finish without user interaction.
Informative Console Output: Provides clear, color-coded feedback on the actions being performed.

🛠️ Technology Stack

Scripting Language: PowerShell
Core Logic: Interacts directly with the Windows Registry and the file system (cmd.exe for RD) to apply its changes.

📐 Architecture & Security Notes

This is a powerful script that makes significant changes to your system's configuration.

Administrator Privileges: This script requires administrator access and will fail without it.
System Modification: The script deletes the contents of the System32\GroupPolicy folders and makes multiple changes to the HKEY_LOCAL_MACHINE section of the registry. This is an intentional part of its design but is an advanced and forceful action.
Reversibility: Reversing these changes requires manually deleting the added registry keys. There is no "undo" function in the script itself.
Intended Use: This script is designed for users who explicitly want to prevent their system from updating past a specific feature release. It may prevent you from receiving new Windows features and non-security updates.
