A factory reset returns a laptop to its like-new state, and both Windows and Mac have it built in: on Windows you use Reset this PC, on a Mac you use Erase All Content and Settings. Before you do anything, back up your files, because a reset erases them. If you are fixing a sluggish or glitchy machine, you can choose to keep your files; if you are selling or recycling it, choose to remove everything and sign out of your accounts first. The whole process is straightforward and does not need a disc, download, or paid tool.
When a reset is the right call
A factory reset is the nuclear option for software problems. It clears years of clutter, removes stubborn malware, and resolves issues that piecemeal fixes cannot. It is also the proper way to prepare a laptop for sale or donation, since it wipes your data and unlinks your accounts.
It will not fix hardware faults, a failing battery, a cracked screen, or a dying drive survive a reset. If the machine is physically failing, resetting only gives you a clean but still-broken laptop. When you simply want more speed, try how to free up RAM in 2026 before going nuclear.

How to reset, step by step
- Back up first. Copy documents, photos, and anything important to cloud storage or an external drive. A reset does not ask twice.
- Sign out of accounts if selling. Deactivate your Microsoft or Apple account and disable device-locating features so the next owner is not blocked.
- Open the reset tool. On Windows go to Settings, System, Recovery, Reset this PC. On Mac go to System Settings, General, then Erase All Content and Settings.
- Choose the right option. Pick Keep my files to fix a machine you are keeping, or Remove everything to wipe it for sale.
- Confirm and wait. The laptop reinstalls the system and restarts. This can take a while, so keep it plugged in.
- Set up or hand it over. If keeping it, sign back in and restore your backup. If selling, leave it at the setup screen for the new owner.
What to skip
- Skipping the backup. This is the one irreversible mistake. Once the reset runs, unsaved files are gone.
- Selling without signing out. Leaving accounts active risks your data and can lock the buyer out via device-protection features.
- Third-party wipe tools for ordinary use. The built-in reset is enough for nearly everyone, including most resale situations.
- Resetting to fix hardware. If the problem is a dying drive or battery, a reset will not help; diagnose the hardware instead.
FAQ
Does a factory reset delete everything?
A full reset erases your files, apps, and settings. Windows also offers a keep-my-files option for repairs. Always back up first, since the wipe is not reversible.
Will a factory reset remove a virus?
A standard reset removes most malware along with everything else. For deeply embedded threats, a full erase with reinstall is the most thorough option.
How long does a factory reset take?
Often from a half hour to a couple of hours, depending on the laptop and drive speed. Keep it plugged in and do not interrupt it.
Do I need to sign out before selling my laptop?
Yes. Deactivate your accounts and disable device-locating features first, so your data is gone and the buyer is not blocked by an activation lock.
