Introduction

Over time, Windows PCs can experience performance degradation due to accumulated software, system errors, or malware. Reinstalling Windows using installation media is an effective method to restore your system's performance and stability. This guide provides a detailed walkthrough of the reinstallation process, ensuring you can confidently refresh your PC.

Understanding Windows Installation Media

What is Installation Media?

Installation media refers to a bootable device—such as a USB flash drive or DVD—that contains the Windows operating system setup files. It allows users to install or reinstall Windows on their computers. Microsoft provides tools to create this media, ensuring users have access to the latest version of Windows.

When to Use Installation Media

Consider using installation media in the following scenarios:

  • System Performance Issues: Persistent slowdowns or unresolvable errors.
  • Malware Infections: Severe infections that cannot be remedied through standard antivirus tools.
  • Hardware Changes: Significant hardware upgrades, like replacing the motherboard.
  • Clean Installation: Removing all existing data and settings for a fresh start.

Preparing for Reinstallation

1. Backup Your Data

Before proceeding, it's crucial to back up all important files to an external drive or cloud storage. Reinstallation can erase data, so safeguarding your information is essential.

2. Verify Windows Activation

Ensure your current Windows installation is activated. Post-reinstallation, Windows should automatically reactivate if it was previously activated. To check activation status:

  • Go to Settings > Update & Security > Activation.
3. Link Digital License to Microsoft Account

Linking your digital license to your Microsoft account simplifies reactivation:

  • Navigate to Settings > Accounts > Your info.
  • Select Sign in with a Microsoft account and follow the prompts.
