Is the previous owner's data wiped from a refurbished laptop?

It should be — and at Whynew it always is.

The storage is securely wiped before a fresh operating system is installed. That's more than just "formatting": a quick format leaves data recoverable, while a secure wipe overwrites or cryptographically erases it.

What you should see on first boot

• A fresh Windows or macOS set-up screen
• No previous user accounts
• No old files, browser history or saved passwords

If you ever see someone else's data on a laptop you bought, contact the seller immediately. Protecting your own data when you sell
