How to Factory Reset a Laptop: Windows and Mac Guide

Knowing how to factory reset a laptop can save you from hours of troubleshooting. Whether you're preparing to sell your device, clearing out malware, or fixing stubborn software errors, a factory reset restores your laptop to its out-of-box state. This guide walks you through the full process for both Windows and Mac, with clear steps for each operating system.

Before you dive in, consider whether a full reset is truly necessary. If your machine is just sluggish, our guide on how to speed up a slow laptop may solve the problem without erasing everything. For tablet owners, the process differs — see our separate guide on how to factory reset a tablet. When a reset is the right call, this guide has you covered on both platforms.

Why Factory Reset a Laptop

Common Reasons to Reset

A factory reset is a complete wipe of your operating system, installed apps, and personal files, returning the laptop to its factory default configuration. People reset their laptops for several reasons:

• Selling or donating the device — removes personal data before it changes hands
• Persistent malware or viruses — when antivirus software can't fully clean an infection
• Major software corruption — broken system files, failed updates, or unbootable Windows/macOS
• Performance degradation — years of accumulated junk, registry clutter, or app conflicts
• Fresh start — clearing everything for a clean, organized setup

When a Reset Is the Right Choice

A reset is a last resort for software issues. Try basic fixes first — clearing startup programs, running disk cleanup, or checking for driver updates. If those fail and problems persist across accounts or after reinstalling key apps, a factory reset is justified. It does not fix hardware failures such as a faulty hard drive or failing RAM. If your laptop won't turn on at all, check whether the issue is hardware before resetting. You can find more tips on our laptops resource page.

Prepare Before You Reset

Back Up Your Data

A factory reset is irreversible. Everything on the drive will be erased. Back up your data before proceeding:

• Copy documents, photos, and downloads to an external drive or cloud storage (Google Drive, OneDrive, iCloud)
• Export browser bookmarks
• Note your software license keys — especially for paid apps
• Sign out of apps that limit device activations (Adobe Creative Cloud, Microsoft Office)

On Mac, use Time Machine with an external drive for a full system backup. On Windows, use File History or manually copy your User folder.

What You'll Need

• Power adapter plugged in — never reset on battery alone
• Your Microsoft or Apple ID credentials
• At least 30–60 minutes of free time
• Stable internet connection (for downloading updates post-reset)

How to Factory Reset a Windows Laptop

Windows 10 and 11 Reset

Microsoft has made factory resetting straightforward from within the Settings app. Follow these steps:

1. Open Settings (Windows key + I)
2. Go to System → Recovery (Windows 11) or Update & Security → Recovery (Windows 10)
3. Click Reset this PC
4. Choose Remove everything to fully wipe the drive, or Keep my files to reinstall Windows while preserving personal files
5. Select Cloud download (downloads a fresh Windows copy) or Local reinstall (uses existing files — faster but may carry over corruption)
6. On the next screen, click Additional settings and enable Clean data if you're selling the laptop — this overwrites the drive so data can't be recovered
7. Click Reset and wait. The process takes 30–60 minutes and restarts several times.

After the reset, Windows runs the initial setup wizard. You'll create or sign into a Microsoft account and reinstall apps from scratch.

Reset from Boot (When Windows Won't Start)

If Windows won't load, you can still reset from the Windows Recovery Environment (WinRE):

1. Force-restart your laptop three times in a row (hold the power button during startup) — Windows automatically enters WinRE
2. Select Troubleshoot → Reset this PC
3. Follow the same steps as above

Alternatively, boot from a Windows installation USB and choose Repair → Reset.

How to Factory Reset a Mac

macOS Ventura and Later (Apple Silicon & Intel)

Apple simplified the reset process in macOS Ventura. If your Mac runs Ventura or later:

1. Click the Apple menu → System Settings
2. Go to General → Transfer or Reset
3. Click Erase All Content and Settings
4. Enter your administrator password and Apple ID password when prompted
5. Confirm — the Mac signs out of iCloud, erases all data, and reinstalls a clean macOS

This takes 20–45 minutes. The Mac restarts into the Setup Assistant, ready for a new user.

Intel Mac or Older macOS via Recovery Mode

For Macs running macOS Monterey or older, or if the system is unresponsive:

1. Restart and immediately hold Command + R until the Apple logo appears
2. Select Disk Utility → choose your startup disk (usually named Macintosh HD)
3. Click Erase, choose APFS format, and confirm
4. Exit Disk Utility and select Reinstall macOS
5. Follow the on-screen steps — requires an internet connection

For Apple Silicon Macs in Recovery, hold the Power button at startup until you see "Loading startup options," then select Options → Continue.

After the Reset: Next Steps

Reinstall Apps and Restore Files

Once your laptop completes the reset and runs through initial setup, work through these steps in order:

1. Install all available OS updates before adding any software
2. Reinstall your browser and restore bookmarks
3. Restore personal files from your backup drive or cloud storage
4. Reinstall productivity apps, then entertainment apps last

If your laptop still feels sluggish after a reset, consider a hardware upgrade. Our guide on how to upgrade laptop RAM can help you get more performance without buying a new machine.

Security Steps After Reset

A clean laptop is a good opportunity to tighten security:

• Use a strong, unique password for your Microsoft or Apple account
• Enable two-factor authentication
• Turn on BitLocker (Windows) or FileVault (Mac) disk encryption
• Install only apps from official stores or trusted publishers

Good habits after a reset can extend your laptop's useful life. Pairing security awareness with battery care practices — as outlined in our guide on how to extend laptop battery life — keeps your device running well long-term.
