Windows 11 is Microsoft’s latest operating system, and while it’s packed with new features and a sleek design, not all computers meet the official system requirements. But don’t worry! You can still install Windows 11 on an unsupported PC with a few tweaks. By using the Windows 11 Installation Assistant and modifying some registry settings, you’ll have the latest OS up and running in no time. Just keep in mind that Microsoft might not support your device fully, so proceed with caution.
How to Install Windows 11 on Unsupported PC
Installing Windows 11 on a PC that doesn’t meet the requirements might sound tricky, but it’s totally doable. Follow these steps to get Windows 11 up and running on your unsupported PC.
Step 1: Backup Your Data
Before making any changes to your system, ensure you have a backup of all your important files.
Accidents happen, and you don’t want to lose precious data during the installation process. Use an external hard drive or cloud storage to keep your files safe.
Step 2: Download Windows 11 Installation Media
You’ll need to download the Windows 11 Installation Assistant from the official Microsoft website.
The Installation Assistant will guide you through the process, but make sure you have a stable internet connection to avoid interruptions.
Step 3: Create a Bootable USB Drive
Once you have the installation media, use a tool like Rufus to create a bootable USB drive.
This USB drive will be your key to installing Windows 11 on your unsupported PC. Make sure your USB has at least 8GB of storage space.
Step 4: Bypass CPU Check
To bypass Microsoft’s CPU check, you’ll need to edit the registry. Press “Windows + R,” type “regedit,” and hit enter. Add a new key under “HKEY_LOCAL_MACHINESYSTEMSetupMoSetup” named “AllowUpgradesWithUnsupportedTPMOrCPU” with a value of 1.
Editing the registry can be risky, so proceed with caution. Double-check your changes to avoid any mishaps.
Step 5: Install Windows 11
Restart your computer and boot from the USB drive to start the Windows 11 installation process.
Follow the on-screen instructions, and soon enough, you’ll be enjoying the new features of Windows 11.
After completing these steps, your unsupported PC will be running Windows 11. You might notice some features don’t work as intended, and Microsoft may not offer updates. But for those eager to try the new OS, this method provides a workaround.
