Windows Upgrade vs. Install

Key Concepts

• Upgrade: Keeps all files and applications, updates the OS underneath.
• Install: Overwrites everything, starts with fresh Windows installation.

Advantages of Upgrading

• Maintains consistency across Windows versions.
• Retains customizations, files, and applications.
• Saves time by avoiding reinstallation of apps and files.
• Ideal for home users with multiple profiles.

In-Place Upgrade

• Conducted from within the existing OS.
• Applications and user files remain intact.
• Minimal additional work post-upgrade.

Clean Install

• Deletes all data and starts anew.
• Requires backup and restoration of files.
• Typically initiated using boot media (USB, DVD).

Creating Boot Media

• Download Windows from the internet.
• Use Microsoft’s media creation tool to make a USB bootable.

Version Compatibility

• 32-bit to 64-bit: Requires clean install.
• 64-bit to 32-bit: Not possible.
• Edition Upgrades: Allowed from same or lower to higher (e.g., Home to Pro).

Checking Upgrade Paths

• Verify available paths via Microsoft documentation.
• Common in-place upgrades:
  • Windows 10: From Windows 7 or 8.1 (not 8.0 directly)
  • Windows 11: Only from Windows 10

Post-Upgrade Steps

• Reboot and verify application functionality.
• Confirm user data installation.
• Use Recovery options for reverting if necessary.

Additional Tasks

• Install service packs and security updates.
• Check and update applications and drivers.
• Ensure all updates via Windows Update.

Summary

Performing a Windows upgrade or installation requires consideration of your needs whether maintaining current settings or starting fresh. Understanding compatibility and upgrade paths is crucial for a successful process.
