Key takeaways
- Back up first and check the backup opens, because a reset cannot be undone.
- Keep my files removes apps and settings; Remove everything erases your files too.
- Before selling or giving the laptop away, choose Remove everything and turn on Clean data.
- Keep the charger plugged in the whole time, and never switch off during a reset.
Quick answer: what does a factory reset actually do?
A factory reset puts Windows back to a fresh state. Windows reinstalls itself, removes the apps you added and resets your settings. Depending on the option you choose, it either keeps your personal files or deletes them as well.
Two points matter before you start. First, a reset is a one-way action. If you did not back up, anything deleted is very hard to bring back. Second, a reset fixes software problems only. It will not repair a failing hard drive, a cracked screen or a bad battery.
Should you reset at all? Reasons that make sense
A reset is a good idea when:
- The laptop is slow or unstable and ordinary clean-up has not helped.
- You suspect a virus that your security software cannot remove.
- Windows has become full of unwanted programs you cannot easily uninstall.
- You are selling the laptop, giving it to someone, or passing it to a new staff member.
It is not the right first step when the problem is a hardware fault. If the laptop is slow because the hard drive is dying, a reset will only waste a day and put your data at risk. Try the simpler things first: restart, install pending Windows updates, uninstall programs you do not use, and check that the drive is not nearly full.
What to do before you reset: the safety checklist
Spend twenty minutes here and the reset becomes a calm job instead of a disaster.
1. Back up everything you cannot replace
Check Documents, Desktop, Downloads, Pictures, Videos and Music. Also check places people forget: browser bookmarks, WhatsApp chat backups, saved game progress, accounting or school data folders, and email files if you use an email program that stores mail on the laptop.
Copy the files to an external drive or a cloud service. Then open the copy and confirm the files actually open. A backup you have not checked is only a hope.
2. Note your licences and logins
Write down the names of paid programs you use and where you bought them. Find your Microsoft Office sign-in details, antivirus licence, and any software that needs a key. Make sure you know the password to your Microsoft account and your Wi-Fi.
3. Sign out of accounts on this laptop
Sign out of Microsoft Office and other paid software, and sign out of services such as Google Chrome sync and iTunes or other apps that limit how many devices you can use. This frees the licence so you can use it on the new setup.
4. Turn off Find my device if it is on
In Windows 11 go to Settings, Privacy and security, Find my device. In Windows 10 go to Settings, Update and Security, Find my device. This matters mostly for a laptop you are giving away, so the new owner is not locked out by your account.
5. Plug in the charger
A reset can take from under an hour to several hours. A power cut part-way through can leave Windows damaged. If NEPA light is unreliable where you are, wait for stable power or use a UPS or inverter, and keep the battery charged as well.
How to factory reset Windows 11 and Windows 10, step by step
Windows 11
- Open Settings (press the Windows key and I).
- Click System, then Recovery.
- Next to Reset this PC, click Reset PC.
- Choose Keep my files or Remove everything (explained in the next section).
- Choose Cloud download or Local reinstall.
- Read the summary screen carefully, then click Reset.
Windows 10
- Open Settings, then Update and Security.
- Click Recovery.
- Under Reset this PC, click Get started.
- Choose Keep my files or Remove everything.
- Choose Cloud download or Local reinstall, then follow the prompts and confirm.
Cloud download or Local reinstall? Cloud download fetches a fresh copy of Windows over the internet. It can use a lot of data, so check your plan or use Wi-Fi you trust. Local reinstall uses files already on the laptop, so it needs no download, but it will not help if those files are damaged. If one option fails, try the other.
The laptop will restart several times and show a percentage. This is normal. Do not press the power button, close the lid or unplug the charger. When it finishes you will see the first-time setup screens, like a brand-new laptop.
Keep my files or Remove everything: which one to choose?
Keep my files removes the apps and settings you added, but keeps the files in your user folders. Choose this to fix problems on a laptop you will keep. Windows saves a list of apps it removed on your desktop, which helps you reinstall them later. Even so, back up first, because no repair process is risk-free.
Remove everything deletes your personal files, apps and settings. Choose this when you are selling, donating or handing over the laptop, or when you want the cleanest possible start.
On the Remove everything path you will see an option such as Change settings. Look for Clean data (called Data erasure in Windows 10). Turn it on if the laptop is leaving your hands. It takes longer, but it overwrites the drive so that ordinary recovery software cannot easily bring your files back. Leave it off if you are keeping the laptop and only want a fresh start.
Also look for Delete files from all drives if the laptop has more than one drive or partition and you want everything erased.
Licence, activation and BitLocker: what to expect
Windows activation. A laptop that came with Windows 10 or 11 normally reactivates by itself after a reset once it is online. You can check under Settings, System, Activation. If you upgraded or changed the motherboard, signing in with the Microsoft account you used before often restores activation too.
Microsoft Office and other paid software. These are not restored by a reset. You reinstall them and sign in or enter the licence you saved earlier.
Drivers. Windows installs most drivers on its own. If Wi-Fi, sound, or the screen brightness controls do not work afterwards, install the drivers from the laptop maker's support page using another device, then carry them across on a flash drive. Always download from the maker's own site.
BitLocker or device encryption. Some laptops encrypt the drive automatically. A reset normally handles this for you, but sometimes the laptop asks for a recovery key at the start. Find it by signing in to your Microsoft account on another device and opening the recovery keys page, or check where your organisation stores it if it is a work laptop. Locate the key before you begin, not after you are locked out.
Work and school laptops. If the laptop belongs to an employer or school, do not reset it without permission. It may be managed, and a reset could lock it or remove required software.
Selling or giving away a laptop: wipe it properly
Deleting files, emptying the Recycle Bin or formatting a drive does not reliably remove data. Free recovery tools can often bring it back. Before the laptop leaves your hands, do all of this:
- Back up everything you want to keep.
- Sign out of Microsoft Office, browsers, messaging apps, and your Microsoft account if you can.
- Remove the laptop from your Microsoft account devices page and turn off Find my device.
- Run Reset this PC, choose Remove everything, and switch on Clean data.
- Let it complete to the first setup screen, then switch it off without signing in. The buyer should do the first setup.
If you remove a drive and keep it, you can physically hand over a laptop with no storage. Do not smash or burn a drive; it is unnecessary and unsafe. If the laptop held very sensitive business or school records, ask a technician to wipe it with proper erasure software and confirm it.
When you are buying, the same rules help you: ask the seller to reset in front of you, or reset it yourself on arrival.
What to do if the reset fails or gets stuck
Message: There was a problem resetting your PC
This means Windows could not complete the reset and has usually left things as they were. Try these in order:
- Restart and try again, using the other option (Cloud download instead of Local reinstall, or the reverse).
- Open Command Prompt as administrator and run sfc /scannow, wait for it to finish, then try again.
- Start the reset from the recovery environment: hold Shift while clicking Restart, then choose Troubleshoot, then Reset this PC.
- Free up space. Resets need free room, so delete large files you already backed up.
Stuck on a percentage for a long time
Resets are slow on older hard drives, and a percentage can sit still for a long while. Give it at least a couple of hours with the charger connected and watch the drive light. If there is no drive activity at all for a long time and nothing changes, a forced shutdown is a last resort, because it can damage the installation.
If nothing works
The cleanest way out is a fresh installation of Windows from installation media made on another computer, using Microsoft's official download page. This erases the drive, so back up first if you still can. If the reset keeps failing, strange errors appear, or the laptop makes clicking sounds, the drive may be failing, and the safest next step is professional help.
When to get help from a technician
Stop and get help if:
- The laptop will not start and you need files from it before any reset.
- You see clicking sounds, repeated drive errors, or the reset keeps failing at the same point.
- It is a work or school laptop, or it is locked by a password or encryption key you cannot find.
- You are not sure you have a good backup. Do not guess; ask first.
A technician can copy your files safely, reinstall Windows, install drivers and confirm that the drive is healthy, so the reset is not repeated a week later.
Frequently asked questions
Does a factory reset delete everything?
It depends on your choice. Keep my files removes apps and settings but keeps documents and photos in your user folders. Remove everything deletes personal files, apps and settings. Neither option is a substitute for a backup, so copy anything important to another drive or cloud storage before you begin.
How long does a factory reset take?
From under an hour to several hours. A modern laptop with an SSD is usually quicker than an older one with a hard drive, and Clean data adds time. Cloud download also depends on your internet speed. Keep the charger connected and do not interrupt the process.
Will a factory reset remove a virus?
It removes most viruses that live in Windows and your apps, particularly with Remove everything. It will not help if you restore infected files from a backup afterwards, so scan your backup before copying files back. Deep-rooted infections are rare but need a technician.
Do I lose my Windows licence after a factory reset?
No, in most cases. Windows 10 and 11 normally reactivate automatically once the laptop is online, because activation is linked to the hardware or your Microsoft account. You can confirm under Settings, System, Activation. Paid programs such as Office need to be installed and signed in again.
Can I factory reset a laptop without a password?
Windows lets you start a reset from the sign-in screen: hold Shift, click Restart, then choose Troubleshoot and Reset this PC. You may be asked for a BitLocker key or an account sign-in. This is for laptops you own. A reset on a locked laptop that is not yours is not something a reputable technician will do without proof of ownership.
Is it safe to sell a laptop after a factory reset?
Yes, if you choose Remove everything with Clean data turned on, sign out of your accounts first, and remove the laptop from your Microsoft account. A simple Keep my files reset or just deleting files is not enough, because personal data may still be recoverable.
