Introduction

This tutorial guides you through the process of upgrading to Windows 11 on older computers without losing your programs and data. If you have an unsupported device and want to continue using it with Windows 11, this step-by-step guide will help you achieve that while highlighting important considerations.

Step 1: Check System Compatibility

Before proceeding with the upgrade, ensure your computer meets the minimum requirements for Windows 11, even if it's considered unsupported.

• Processor: 1 GHz or faster with at least 2 cores on a compatible 64-bit processor.
• RAM: Minimum 4 GB.
• Storage: At least 64 GB of free space.
• TPM: Trusted Platform Module version 2.0 is generally required.
• Graphics: DirectX 12 compatible graphics with a WDDM 2.0 driver.

Tip: Use the PC Health Check tool from Microsoft to verify compatibility.

Step 2: Backup Your Data

Before making any major changes, it's important to back up your data.

• Use Built-in Tools: Utilize Windows Backup or File History to create a backup.
• External Storage: Copy important files to an external hard drive or cloud storage.

Common Pitfall: Failing to back up your data can result in loss during the upgrade.

Step 3: Download Windows 11 Installation Media

To upgrade, download the Windows 11 installation media.

• Navigate to the Microsoft Windows 11 download page.
• Choose the “Create Windows 11 Installation Media” option.
• Follow the on-screen instructions to create a bootable USB drive or download an ISO file.

Step 4: Modify Registry for Unsupported Hardware

To bypass hardware checks, you will need to modify the Windows Registry.

1. Press Windows + R to open the Run dialog.
2. Type regedit and hit Enter to open the Registry Editor.
3. Navigate to the following path:

   HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
   

4. Right-click in the right pane, select New, then DWORD (32-bit) Value.
5. Name it AllowUpgradesWithUnsupportedTPMOrCPU.
6. Set the value to 1.

Tip: Be cautious when editing the registry; incorrect changes can affect system stability.

Step 5: Initiate the Upgrade

Now that you've prepared everything, it’s time to begin the upgrade.

• Insert the bootable USB drive or mount the ISO file.
• Run the setup.exe file from the USB or ISO.
• Choose the option to keep personal files and apps when prompted.

Step 6: Follow On-Screen Instructions

During the installation, follow the prompts carefully.

• Accept the license terms.
• Choose the installation type (Upgrade).
• Windows will guide you through the remaining steps.

Tip: Ensure your device is plugged into a power source during the installation process to avoid interruptions.

Step 7: Post-Installation Setup

After installation, you may need to perform some additional configurations.

• Check for Windows updates to ensure all drivers are up to date.
• Verify that all your programs are functioning properly.
• Restore any data if needed.
