Windows 10 End of Support: Should I Clean Install Windows 11 or Upgrade?

Should I clean install Windows 11 or just upgrade to Windows 11? Microsoft recommends a clean install for optimal performance and to avoid carrying over potential issues from Windows 10. 

Why Clean Install

How is a clean install different from an upgrade? Why should you select a clean install or an in-place upgrade? Here are the reasons:

Fresh Start:

• A clean install ensures a clean slate, free from any remnants of old files, settings, or potential problems from Windows 10. 

Potential Problem Avoidance:

• It eliminates the possibility of carrying over undetected malware or registry debris from Windows 10. 

Re-evaluation of Programs:

• A clean install allows you to carefully choose and reinstall the necessary programs, potentially removing bloatware or trial software. 

Configuration Changes:

• It allows configuration adjustments, such as changing data storage locations and upgrading hardware like SSDs or adding backup drives. 

Clean Install vs. In-place Upgrade

Check the table below to get more detailed differences between a clean install of Windows 11 and an in-place upgrade.

Clean Install Windows 11:

🎈A clean install involves wiping the old Windows 10 installation and installing Windows 11 from scratch. It's the recommended method to ensure a fresh start and better performance, as you won't be carrying over any legacy and performance issues from Windows 10. 

🔥A clean install is ideal if:

• You met performance issues, malware, or clutter.
• You want a fresh start with maximum stability
• You want to manage and reinstall

In-place Upgrade:

🎈This method installs Windows 11 on top of your existing Windows 10 installation, retaining your files, settings, and applications. While it is convenient, it may not resolve potential issues from Windows 10. 

🔥An upgrade is ideal if:

• Windows 10 runs smoothly, and you want minimal disruption.
• You don't want to lose data.
• You lack the technical experience to reinstall Windows 11.

If you do not want to clean install Windows 11, read this post to learn how to perform an in-place upgrade.
