Full PowerShell Script: Windows 10 to Windows 11 Upgrade with Logging Powershell

step-by-step guide with an integrated PowerShell script that performs the following tasks:

1. Checks system requirements for Windows 11 (TPM, Secure Boot, CPU, RAM, and storage).
2. Downloads the Windows 11 Installation Assistant.
3. Upgrades to Windows 11 silently.
4. Logs the entire process (system checks, download, upgrade, and monitoring the process).

This script will log each significant action to a log file for tracking, and it will also display the log in the console for real-time feedback.

Step-by-Step Breakdown of the Script

1. Log File Initialization

• A log file (C:\Windows11UpgradeLog.txt) is defined to track the script’s execution.
• The Write-Log function writes all log messages both to the console and the log file.

2. System Requirements Check (Check-SystemRequirements)

• This function checks the system for the following requirements:
  • TPM 2.0 (Trusted Platform Module)
  • Secure Boot enabled
  • 64-bit CPU architecture
  • At least 4GB of RAM
  • At least 64GB of storage space
• The function logs each check and returns True if all requirements are met; otherwise, it logs why the system does not qualify for an upgrade.

3. Download Windows 11 Installation Assistant (Download-Windows11Installer)

• This function uses Invoke-WebRequest to download the Windows 11 Installation Assistant executable (Windows11Setup.exe) from the official Microsoft URL.
• It logs the download process, including the file path where it is saved.

4. Upgrade to Windows 11 (Upgrade-Windows11)

• Once the installer is downloaded, the script uses Start-Process to start the upgrade silently (/auto upgrade /quiet /noreboot).
• It logs the start of the upgrade process and any errors if the installer path is invalid.

5. Monitor Upgrade Status (Monitor-UpgradeStatus)

• The script checks for the presence of the setup process (which is the Windows 11 upgrade process).
• It logs the status of the upgrade, repeating the check every 30 seconds, until the process completes.

6. Main Execution Flow

• The script first checks if the system meets the minimum requirements (Check-SystemRequirements).
• If the system passes, it proceeds to download the Windows 11 Installation Assistant (Download-Windows11Installer), starts the upgrade (Upgrade-Windows11), and monitors the upgrade status (Monitor-UpgradeStatus).
• Each step is logged for easy tracking.
