How to Install Windows 11 on Unsupported PC: Step-by-Step Guide

Want to install Windows 11 on an unsupported PC? Well, it’s totally possible, but it requires a little bit of elbow grease. The main thing you need to do is tweak your system settings and create a bootable USB drive. After that, you can bypass Microsoft’s hardware checks. Follow the steps below to get Windows 11 up and running on your unsupported PC.

How to Install Windows 11 on Unsupported PC

Alright, let’s get into the nitty-gritty. These steps will guide you through creating a bootable USB drive, tweaking your settings, and installing Windows 11. By the end, you’ll have a shiny new OS on your old hardware.

Step 1: Check Your Hardware

First, make sure your PC meets the minimum system requirements.

Even though your PC is "unsupported," it should at least have a 64-bit processor, 4GB of RAM, and 64GB of storage. If not, you might run into performance issues down the road.

Step 2: Backup Your Data

Before diving into installation, back up all your important files.

You never know what might go wrong during an OS install. Better safe than sorry! Use an external hard drive or cloud storage.

Step 3: Download the Windows 11 ISO

Go to Microsoft’s official website and download the Windows 11 ISO file.

You’ll need this file to create a bootable USB drive. Make sure you download the version that matches your language and edition (Home, Pro, etc.).

Step 4: Create a Bootable USB Drive

Use a tool like Rufus to create a bootable USB drive from the ISO file.

Plug in a USB drive with at least 8GB of space. Open Rufus, select the ISO file, and follow the prompts to create your bootable drive.

Step 5: Modify the Registry

Press Win + R, type "regedit" and hit Enter to open the Registry Editor.

Navigate to HKEY_LOCAL_MACHINESYSTEMSetupMoSetup. If the MoSetup key doesn’t exist, create it. Then, add a new DWORD (32-bit) Value named "AllowUpgradesWithUnsupportedTPMOrCPU" and set it to 1.

Step 6: Boot from the USB Drive

Restart your PC and boot from the USB drive.

You may need to change the boot order in your BIOS/UEFI settings to prioritize the USB drive. Once done, you’ll see the Windows Setup screen.

Step 7: Install Windows 11

Follow the on-screen instructions to install Windows 11.

When prompted, choose "Custom: Install Windows only (advanced)" and select the partition where you want to install Windows 11. The process will take a while, so sit back and relax.

After you complete these steps, your PC will reboot a few times. You’ll eventually reach the Windows 11 setup screen, where you’ll configure settings like language, region, and keyboard layout. And voila, you’re in!

Tips for Installing Windows 11 on Unsupported PC

  1. Disable Secure Boot and TPM: Sometimes, you’ll need to disable Secure Boot and TPM in your BIOS/UEFI settings to get things rolling.

  2. Keep Drivers Handy: Outdated or missing drivers can cause issues. Make sure you have the latest drivers downloaded.

  3. Use a Secondary Device: If possible, keep a secondary device nearby for troubleshooting and looking up guides.

  4. Expect Bugs: Since you’re installing on unsupported hardware, you might encounter bugs or glitches. Be prepared to troubleshoot.

  5. Regular Backups: Always keep a backup of your data. Unsupported installations can be a bit unpredictable.
