Here’s a detailed guide for performing a clean installation of Windows 10. This process ensures your system starts fresh without retaining files, apps, or settings from the previous installation.

Step 1: Backup Your Data

Before starting, ensure you back up any essential data. A clean installation will erase everything on the drive where Windows is installed. Consider using:

• External Drives: Save personal files, photos, and documents on an external hard drive or USB.
• Cloud Storage: Use platforms like OneDrive, Google Drive, or Dropbox for safe online backups.
• Backup Software: Tools like Macrium Reflect or Acronis True Image provide a comprehensive way to safeguard your data.

Step 2: Create a Bootable USB Drive

To install Windows 10, you’ll need a bootable USB drive. Follow these steps:

1. Download the Media Creation Tool:
   • Visit Microsoft’s Windows 10 download page.
   • Download the Media Creation Tool and run it.
2. Create the Installation Media:
   • Choose the option “Create installation media for another PC.”
   • Select your language, edition (Windows 10 Home, Pro, etc.), and architecture (32-bit or 64-bit).
   • Insert a USB drive with at least 8GB of space and follow the prompts to create the bootable drive.

Step 3: Configure Your PC to Boot from USB

1. Access BIOS/UEFI:
   • Restart your computer and press the appropriate key (often F2, F12, DEL, or ESC) during startup to enter BIOS/UEFI settings.
2. Set Boot Priority:
   • In the BIOS/UEFI menu, locate the boot priority section.
   • Set your USB drive as the primary boot device.
3. Save Changes and Exit:
   • Save the settings and restart your PC with the bootable USB inserted.

Step 4: Start the Installation

1. Boot from USB:
   • Your PC should boot from the USB drive. If it doesn’t, double-check the boot order in BIOS/UEFI.
2. Choose Install Settings:
   • Select your language, time, and keyboard preferences, then click “Next.”
   • Click “Install Now” to begin.
3. Enter Product Key:
   • If prompted, enter your Windows 10 product key. You can skip this step if your PC already has an activated license.
4. Choose Installation Type:
   • Select “Custom: Install Windows only (advanced)” for a clean installation.

Step 5: Format the Drive

1. Select a Drive:
   • You’ll see a list of drives and partitions. Select the partition where Windows is currently installed.
2. Format the Partition:
   • Click “Format” to erase all data on that partition.
   • If you want to start completely fresh, delete all partitions, then create a new one.
3. Proceed with Installation:
   • Once the drive is ready, select it and click “Next” to begin the installation.

Step 6: Initial Setup

After the installation, your PC will restart multiple times. Follow these steps to complete the setup:

1. Region and Keyboard Layout:
   • Confirm your region and keyboard layout.
2. Network Setup:
   • Connect to Wi-Fi or skip if you’re using a wired connection.
3. Sign In with a Microsoft Account:
   • Use your Microsoft account credentials or create a new account.
   • Alternatively, choose “Offline Account” for a local user profile.
4. Privacy Settings:
   • Customize privacy settings based on your preferences.
5. Finish Setup:
   • Windows will finalize the installation. This may take a few minutes.

Step 7: Install Drivers and Updates

1. Update Windows:
   • Go to Settings > Update & Security > Windows Update and check for updates.
2. Install Drivers:
   • Visit your device manufacturer’s website to download and install the latest drivers.
3. Install Applications:
   • Reinstall necessary apps and tools from trusted sources.

Step 8: Secure Your System

1. Set Up Antivirus:
   • Use Windows Defender or install a third-party antivirus for added protection.
2. Enable Backups:
   • Turn on File History or set up system restore points for ongoing protection.
3. Secure Your Account:
   • Use a strong password or PIN and consider enabling Windows Hello for biometric security.
