Wipe Everything on Your Laptop For Windows – 100% Factory Reset

There are the following ways to wipe laptop before selling. You begin the process and take the necessary backups of your important data.

1. Back Up Your Data

The foremost approach should be to protect your essential files before erasing anything.

• External storage: Use an external USB hard drive or SSD for copies of documents, pictures, and videos.
• Cloud Storage: Store files in Google Drive, Dropbox, iCloud, or OneDrive.
• Browser Data: Export your browser bookmarks, email archives, application settings, etc.

After you back it up, make sure your files are opening well in all the new places.

2. Sign Out of Your Accounts

If you want to avoid problems for the new owner (and for yourself), begin by logging out of services connected to your laptop.

• Windows: Signing Out of Microsoft account, OneDrive, and Office 365.
• Mac: Log out of iCloud, iMessage, and FaceTime.

Software Licenses: Some paid programs need the license deactivated just before swapping devices.

3. Methods for Wiping Laptop Before Selling using Built-in Factory Reset Options

A. Using Windows Built-In Reset Tool

• Go to Settings → Update & Security → Recovery.
• Next, on Reset this PC, select Get started.

• Select “Update and Security” –> from the Recovery from the Settings menu.

• Choose “Get started” from the “Reset this PC” menu.

• Pick “Remove everything” to remove all files, apps, and configurations.

You have one option there to remove apps and settings but safely keep all your data.

B. Wiping with Installation Media

If you want a completely new system:

• Windows: Install Windows Media Creation Tool from Microsoft
• Create a bootable USB installer.
• Use USB to boot, select Custom Install, delete all partitions, and install a fresh copy of Windows.

This method will wipe all drives and delete any lingering recovery partitions.

C. Using Third-Party Wiping Tools

To obtain even more security, look at applications that are made to overwrite files:

• SysTools Data Erasure Software – Erases drive, disk, files/folders quickly
• Eraser — provides shredding of selective files/folders
• CCleaner Drive Wiper – Provides multi-pass overwriting.

Use these if your laptop has sensitive data.

4. Reinstall Windows 11 or 10

• You may wipe your laptop and then reinstall Windows to make sure the OS is a fresh new laptop with no footprint of your data left behind.
• Using the Windows Media Creation Tool, which makes a bootable pendrive (USB) to ensure a clean Windows installation of Windows 10/11.

Physically Remove and Destroy the Hard Drive

Physically destroying the hard drive will ensure that data can never be recovered. This is the only true way to guarantee security, especially if the laptop will not be refurbished.

Steps to perform:

Turn Off and Disconnect: Make sure the laptop is powered down entirely and disconnected from any power source.

Open the Laptop Case: Use an appropriate tool to open the laptop case.

Find the hard disk and eliminate it: Step-by-step removal of the drive.

Smash the Drive: Smash the platters or circuitry with a hammer or drill.

Dispose Properly: Follow local e-waste disposal laws.

5. Methods for Wiping a Mac Laptop

A. macOS Built-In Erase and Reinstall

Create a backup of your data via Time Machine or in another way:

• Log out from iCloud, iMessage & other Apple Services
• Reboot while holding Command(⌘) + R to enter Recovery Mode.
• In Disk Utility, select your main drive and click on Erase (APFS or Mac OS Extended format).
• Choose Reinstall macOS from the menu bar and quit Disk Utility.

B. Erasing via macOS Ventura/Sonoma’s New Option

For users on macOS Monterey or later versions, Apple provides a fast alternative:

• Open System Settings → General → Transfer or Reset.
• Choose Erase All Content and Settings.
• Simply follow the prompts to erase and set it up again.

This method is quicker and easier, but not as secure since it erases all user information and settings.

C. Using Secure Erase Options

Disk Utility is capable in older versions of macOS — when you click the Erase button, you get a Security Options button where you can choose to complete several overwriting passes for additional security. This is more impactful with HDDs than with SSDs since, with SSDs, overwriting is handled differently.
