What a Factory Reset Does and When to Use It

A factory reset removes all your files, programs, and settings and returns your Windows computer to the state it was in when it left the factory. Everything you installed after you first turned it on — documents, photos, applications, browser history — gets deleted. Your operating system is reinstalled fresh.

You should factory reset when your computer has become too slow to use, when malware or viruses won't go away with standard removal tools, when you are selling or giving away the machine, or when Windows itself has become so corrupted that repairs have failed. It is not the first step to try; it is the last one after other fixes have not worked.

A factory reset takes between 30 minutes and two hours depending on your computer's speed and whether you choose to keep your files (which takes longer). You will need your Windows password and, if you have a Microsoft account, your login credentials.

Key Takeaways

  • A factory reset deletes all your files, programs, and personal settings and reinstalls Windows from scratch, so back up anything you want to keep before you start.
  • Windows 10 and 11 both have a built-in reset tool called Reset this PC, found in Settings under System, and you can choose to keep or remove your files.
  • If your computer will not start or you cannot log in, you can reset from the Windows recovery screen by restarting and pressing the correct key during startup.
  • After the reset completes, you will need to reinstall your programs and sign back into your accounts, which can take several hours depending on how many applications you used.

Back Up Your Files Before You Start

Before you reset, copy anything you want to keep to an external drive, cloud storage, or another computer. A factory reset is permanent — once it finishes, your files are gone and cannot be recovered. This includes documents, photos, videos, music, email, and any other personal data stored on the computer.

The fastest way to back up is to plug in an external hard drive or USB drive with enough space, then open File Explorer, select your user folder (usually labeled with your name), and drag it to the external drive. If your files are too large for an external drive, you can use cloud storage like OneDrive, Google Drive, or Dropbox instead — sign in, upload your folders, and they will be there after the reset.

If you have programs you paid for or licenses you need to reactivate, write down the product keys or take screenshots of them now. You will need these to reinstall after the reset.

How to Reset Windows 10 or 11 Using Settings

The easiest way to reset is through the Settings app if your computer still starts and you can log in. Open Settings by pressing the Windows key and typing "settings," then click the Settings app. Go to System (the first option on the left), scroll down, and click Recovery.

Under "Recovery options," you will see a button labeled "Reset this PC." Click it. Windows will ask whether you want to keep your files or remove everything. Choose "Remove everything" for a true factory reset. If you choose "Keep my files," Windows will delete your programs and settings but leave your personal documents and photos — this is faster but does not clean as thoroughly.

Windows will then ask how you want to reinstall: "Cloud read" downloads a fresh copy of Windows from Microsoft's servers (requires internet), and "Local reinstall" uses a copy already on your computer (faster if your internet is slow). Choose cloud read unless your internet connection is very unreliable. Click Next, review the summary, and click Reset. Your computer will restart and the process will begin.

Resetting When Windows Will Not Start

If your computer will not start normally or you cannot log in, you can reset from the Windows recovery screen. Restart your computer and watch the screen carefully. As soon as you see the Windows logo or a spinning circle, press and hold the power button until the computer shuts down completely. Wait 10 seconds, then turn it back on. Repeat this two or three times — on the third or fourth restart, Windows will detect the problem and show you recovery options.

When the recovery screen appears, look for an option that says "Troubleshoot" or "Reset this PC." Click it, then follow the same steps as above: choose "Remove everything," select your reinstall method, and confirm. The process will take longer from this screen because Windows is working harder to repair itself, but the steps are identical.

If the recovery screen does not appear after several restart attempts, your computer may have a hardware problem rather than a software one. In that case, a factory reset will not help, and you should take the computer to a repair shop or contact the manufacturer.

What Happens During and After the Reset

Once you click Reset, your computer will restart and show a progress bar. Do not turn it off or unplug it — let it run to completion even if it seems stuck. The progress bar may stay at the same percentage for several minutes; this is normal. The entire process usually takes 45 minutes to two hours.

When the reset finishes, your computer will restart and show the Windows setup screen, just like when it was brand new. You will need to choose your language, accept the license agreement, and create or sign into a user account. If you have a Microsoft account (an email address you use for Outlook, OneDrive, or Xbox), sign in with that. If not, you can create a local account with just a username and password.

After setup completes, you will have a clean Windows installation with no programs except the ones that came with it. You will need to reinstall everything you use: your web browser, Office, Zoom, Slack, games, photo editors, and any other applications. read them from their official websites or from the Microsoft Store. This can take several hours if you had many programs installed.

Reinstalling Programs and Restoring Your Files

Start by reinstalling the programs you use most: your web browser, email client, and any work or creative software. read each one from its official website, not from random read sites, because those can contain malware. If you paid for software, you will need to enter your license key or sign in to your account to reactivate it.

Once your programs are installed, restore your backed-up files. If you backed up to an external drive, plug it in, open File Explorer, and copy your files back to your user folder. If you backed up to cloud storage, sign into your account (OneDrive, Google Drive, Dropbox, etc.) and read your files. This is also a good time to sign back into your email, social media, and other online accounts.

After you have reinstalled your programs and restored your files, run Windows Update to make sure you have the latest security patches. Press the Windows key, type "update," and click "Check for updates." Let Windows read and install any available updates, and restart if prompted.

Troubleshooting Common Reset Problems

If the reset gets stuck on a progress bar for more than three hours, restart your computer by holding the power button for 10 seconds, then try the reset again. Sometimes the process stalls and needs to be restarted.

If you see an error message during reset, write down the exact error code and search for it on Microsoft's support website or on a search engine. Common errors include "We couldn't reset your PC" (usually caused by corrupted system files) or "The drive where Windows is installed is locked" (caused by security software blocking the reset). Most of these errors have documented solutions on Microsoft's site.

If your computer will not start even after the reset completes, the hard drive itself may be failing. In that case, you will need to replace the hard drive or take the computer to a repair shop. A factory reset cannot fix hardware failure.

Frequently Asked Questions

Will a factory reset remove viruses and malware?

Yes. A factory reset deletes everything on your computer and reinstalls Windows, so any malware is removed. However, if the malware came from a file you read again after the reset, you can get infected again. Be careful what you read, use antivirus software, and keep Windows updated.

Can I cancel a factory reset once it starts?

You can cancel during the initial setup steps before the actual reset begins, but once the progress bar starts and Windows begins deleting files, you cannot safely cancel without risking data loss or a broken installation. Let it run to completion.

Do I need a Windows installation disc or USB drive?

No. If you use the Settings app method or the recovery screen, Windows downloads or uses a copy already on your computer. You only need a disc or USB if your computer will not start at all and you want to do a manual reinstall, which is more complicated.

Will my Microsoft account be deleted?

No. Your Microsoft account exists on Microsoft's servers, not on your computer. After the reset, you can sign back in with the same email and password. Your OneDrive files, Outlook email, and other cloud data will still be there.

How long does it take to reinstall all my programs?

The reset itself takes 45 minutes to two hours, but reinstalling all your programs can take several more hours depending on how many you had and how fast your internet is. Plan for a full afternoon or evening if you had many programs installed.
