Silent Windows 11 Upgrade Script

This PowerShell script enables silent in-place upgrades to Windows 11, specifically designed for systems that fail compatibility checks when attempting major version upgrades through Windows Update.

Purpose

Windows 11 systems on older major versions (21H2, 22H2) often cannot upgrade to newer versions (23H2, 24H2) via Windows Update due to failing compatibility checks. This script bypasses these limitations by:

• Bypassing TPM, CPU, and other hardware compatibility checks
• Enabling in-place upgrades even on "unsupported" hardware
• Providing a completely silent, no-interaction upgrade process
• Automatically handling all aspects of the upgrade, including reboots

Features

• Bypasses Hardware Requirements: Overcomes TPM, CPU, RAM, SecureBoot and other compatibility blocks
• Automated ISO Handling: Downloads or uses local ISO files (configurable)
• Dependency Management: Automatically installs 7-Zip if not present
• Silent Operation: Runs completely in the background with no user interaction
• Configurable Reboots: Supports automatic or manual reboot options
• Detailed Logging: Provides comprehensive monitoring of the upgrade process
• Cross-Version Compatibility: Works for upgrading from Windows 10 to 11, or between Windows 11 versions

Usage

1. Download: Clone or download this script to your system
2. Configure: Edit the parameters at the top of the script:

   # ISO source (direct URL, local file, or network share)
   $WIN11_ISO_SOURCE = "path-to-iso-or-url"
   
   # Reboot behavior
   $ALLOW_AUTOMATIC_REBOOT = $true  # Set to $false to prevent automatic reboots
   

3. Execute: Run the script with administrative privileges

   powershell.exe -ExecutionPolicy Bypass -File "C:\path\to\DirectWindowsUpgrade.ps1"
   

Process Details

• The script extracts the Windows 11 ISO using 7-Zip
• Registry keys are set to bypass hardware compatibility checks
• Setup files are prepared with appropriate parameters
• The upgrade process runs completely silently
• By default, the system will reboot automatically when needed
• Total upgrade process takes approximately 1.5 hours to complete

Requirements

• Windows 10 or Windows 11 system
• Administrative privileges
• Internet access (if using download URL) or access to Windows 11 ISO
• 10GB+ free space for the upgrade process

ISO Source

For best results, use the business editions of Windows 11 with this script. You can obtain ISOs from:

• Official Microsoft sources
• MassGrave Genuine Windows ISOs

Make sure to use an ISO that contains the Windows 11 version you want to upgrade to (e.g., 23H2, 24H2).

When to Use This Script

• When Windows Update fails to offer major Windows 11 version upgrades
• When systems have "unsupported" hardware that blocks updates
• When you need to perform silent, unattended upgrades
• For bulk upgrades across multiple systems with similar hardware

Logs and Monitoring

The script generates several log files to help monitor progress:

• C:\Win11_Upgrade_Progress.log - Main progress log
• C:\Win11_Monitor.log - Process monitoring log
• C:\Win11_Upgrade_Completed.log - Created upon successful completion

Customization

All configurable parameters are at the top of the script:

• $WIN11_ISO_SOURCE - Source location for Windows 11 ISO
• $WORKING_DIR - Main working directory
• $TEMP_DIR - Temporary directory for downloads
• $LOG_FILE - Main log file path
• $MONITOR_LOG - Process monitor log path
• $ALLOW_AUTOMATIC_REBOOT - Enable/disable automatic reboots
