If you’ve got an older PC and want to upgrade to Windows 11 without losing your data, you’re in luck. You can bypass Microsoft’s hardware requirements with a few tweaks. This guide shows you how to install Windows 11 on an unsupported PC while keeping all your files intact.

Step-by-Step Tutorial: How to Install Windows 11 on Unsupported PC without Data Loss

This section will guide you to install Windows 11 on an unsupported PC. By following these steps, you will bypass hardware restrictions and upgrade without losing any of your precious data.

Step 1: Backup Your Data

Make sure to back up all important files before you begin.

Even though this process aims to keep your data intact, it’s always smart to have a backup. Use an external drive or a cloud service to ensure your files are safe.

Step 2: Download Windows 11 ISO

Visit the official Microsoft website and download the Windows 11 ISO file.

The ISO file is essentially a digital copy of the Windows 11 installation disc. Save it to a location on your PC where you can easily access it.

Step 3: Create a Bootable USB Drive

Use a tool like Rufus to create a bootable USB drive with the Windows 11 ISO.

Rufus is a free tool that helps you create bootable USB drives. Open Rufus, select the ISO file, and click ‘Start’ to create your bootable drive.

Step 4: Edit the Registry

Before installing, you need to tweak your registry settings to bypass hardware checks.

Open the Registry Editor by typing "regedit" into the Run dialog (Win + R). Navigate to HKEY_LOCAL_MACHINESYSTEMSetup, right-click, and create a new key named "LabConfig." Inside this key, create two DWORD values: BypassTPMCheck and BypassSecureBootCheck. Set both to 1.

Step 5: Start the Installation

Insert the bootable USB drive and restart your PC to boot from it.

Press the appropriate key (usually F12, F10, or Esc) during startup to enter the boot menu. Select your USB drive to start the installation process.

Step 6: Follow the On-Screen Instructions

Proceed with the installation as prompted by the Windows 11 installer.

You’ll go through various screens asking for your preferences and license agreement. Follow these as you would for a regular installation.

Step 7: Select Custom Installation

Choose "Custom: Install Windows only" to proceed without data loss.

This option allows you to install Windows 11 while keeping your existing files and applications intact.

Step 8: Complete the Installation

Let the installer run its course and complete the process.

After some time, your system will reboot multiple times. Once it’s done, you’ll be greeted by the Windows 11 setup screen.

After you complete these steps, your PC will boot into Windows 11, retaining all your files and applications.
