Presentation – Clean Install Windows 11 – Step by Step

Learn how to perform a clean installation of Windows 11 with this step-by-step guide. From checking system requirements to backing up files, creating bootable media, and setting up your PC — here’s everything you need.

Introduction

If your computer feels slow, full of errors, or cluttered with unwanted apps, performing a clean installation of Windows 11 is the best solution. Unlike an upgrade, a clean install completely wipes your drive and gives you a fresh start. This guide will walk you through the process in simple steps so you can enjoy a faster and cleaner PC.

Step 1: Check System Requirements

Before installing Windows 11, make sure your device meets the minimum requirements:

  • Processor: 1 GHz or faster with at least 2 cores (64-bit)
  • RAM: 4 GB or more
  • Storage: 64 GB or more
  • Firmware: UEFI with Secure Boot
  • TPM: Trusted Platform Module 2.0
  • Graphics: DirectX 12 compatible
  • Internet: Required for activation and updates

👉 Tip: Use Microsoft’s PC Health Check Tool to confirm if your computer supports Windows 11.

Step 2: Backup Your Important Files

Since a clean install erases everything, always back up your data first. You can:

  • Save files to an external hard drive or USB stick
  • Upload to cloud services like OneDrive, Google Drive, or Dropbox
  • Create a full system image if you want to restore later

Step 3: Create a Bootable USB Drive

You’ll need installation media for Windows 11. Here’s how to make a bootable USB:

  1. Visit Microsoft’s official Download Page.
  2. Download and open the Media Creation Tool.
  3. Insert a USB drive (at least 8 GB).
  4. Select Create installation media.
  5. Choose language, edition, and architecture (64-bit).
  6. Let the tool prepare your USB drive.

Now your USB is ready to install Windows 11.

Step 4: Boot From the USB Drive

  1. Plug the USB into your PC.
  2. Restart your computer.
  3. Enter the Boot Menu (keys like F2, F12, ESC, or DEL).
  4. Select the USB drive to boot.

The Windows 11 setup screen should appear.

Step 5: Start the Installation

Once setup begins:

  1. Select your language and keyboard.
  2. Click Install Now.
  3. Enter your product key (or skip for later).
  4. Choose your Windows 11 edition.
  5. Accept the license terms.

Step 6: Choose Custom Installation

When asked how you want to install, select:
Custom: Install Windows only (advanced).

This option performs a clean installation instead of upgrading.

Step 7: Delete Old Partitions

You’ll now see a list of partitions. To wipe your drive:

  1. Select each partition on your system drive (usually Drive 0).
  2. Click Delete until only Unallocated space remains.
  3. Highlight unallocated space and click Next.

Windows will create new partitions automatically and begin installation. This may take 10–30 minutes.

Step 8: Complete Setup

After installation, your PC will restart. Follow the prompts:

  • Select country and keyboard layout
  • Connect to Wi-Fi
  • Sign in with a Microsoft account (or offline account if allowed)
  • Create a PIN
  • Choose privacy and update settings

You’ll then arrive at the Windows 11 desktop.

Step 9: Install Updates and Drivers

For smooth performance:

  1. Go to Settings > Windows Update and install updates.
  2. Download drivers (graphics, sound, network) from your PC manufacturer’s website.
  3. Restart when required.

Step 10: Reinstall Apps and Restore Files

Finally, reinstall your favorite apps (such as browsers, Office, or games) and copy back your backed-up files. Now you have a clean and fast Windows 11 system.

Conclusion

Doing a clean installation of Windows 11 may take some time, but it’s the best way to refresh your PC. By checking system requirements, backing up data, creating a bootable USB, and carefully following the setup steps, you’ll enjoy a smooth and clutter-free Windows experience.
