Before selling your laptop, factory resetting it is the single most important thing you can do to protect your personal data. This guide shows you exactly how to do it on Windows and Mac — step by step.
⚠️ Never sell a laptop without factory resetting it. Your browsing history, saved passwords, photos, banking apps, and personal files are all at risk if you skip this step.

After the Reset — What Happens to Your Data?
