What a Factory Reset Does and When to Use It

A factory reset removes all your files, programs, and settings from your PC and returns it to the state it was in when it left the manufacturer. This means your documents, photos, installed software, and custom settings will be gone. Windows itself stays on the machine, but it will be a clean copy with no trace of your personal data.

You might reset your PC if it runs slowly, has persistent virus or malware problems that antivirus software cannot fix, you are selling or giving it away, or you want to start fresh after years of accumulation. A reset is more thorough than restarting your computer — it is a complete wipe and reinstall of the operating system.

Before you start, back up any files you want to keep. Copy them to an external drive, cloud storage, or another computer. Once the reset begins, there is no way to recover deleted files.

Key Takeaways

  • Back up all your files to an external drive or cloud storage before starting, because a factory reset deletes everything on your PC.
  • Windows 10 and Windows 11 both have a built-in reset tool in Settings that you can use without any special software or discs.
  • You can choose to keep your Windows installation and remove only your files and programs, or remove everything including Windows and reinstall it fresh.
  • The reset process takes 30 minutes to two hours depending on your PC speed and which option you choose.
  • Your PC will restart several times during the reset — do not unplug it or turn it off while the process is running.

How to Reset Windows 10

Open the Settings app by pressing the Windows key and typing "Settings," then press Enter. Click the gear icon if it appears, or look for "Settings" in your Start menu. Once Settings is open, click System on the left side, then scroll down and click Recovery.

Under the "Reset this PC" section, click the blue get your free guide button. Windows will ask you to choose between two options: Keep my files or Remove everything. If you choose "Keep my files," Windows removes all your programs and settings but leaves your personal documents, photos, and music. If you choose "Remove everything," the entire drive is wiped clean and Windows is reinstalled from scratch — this takes longer but is more thorough.

After you choose, Windows will show you a list of programs that will be removed. Review this list to make sure nothing surprises you. Click Next, then Reset. Your PC will restart and the process will begin. Do not turn off your computer or unplug it during this time. The reset typically takes 45 minutes to two hours.

How to Reset Windows 11

The process in Windows 11 is nearly identical to Windows 10. Press the Windows key, type "Settings," and press Enter. Click System on the left, scroll down, and click Recovery. You will see a section labeled "Reset this PC" with a blue button that says Reset PC.

Click Reset PC and choose between Keep my files or Remove everything. The "Keep my files" option removes programs and settings but preserves your personal files. The "Remove everything" option wipes the entire drive and reinstalls Windows 11 fresh. Select your choice and click Next.

Windows 11 will show you which programs will be removed and ask you to confirm. Click Reset to begin. Your computer will restart multiple times. The entire process usually takes one to two hours. Your screen may go black or show a spinning circle — this is normal. Leave your PC plugged in and do not interrupt the process.

What to Do If You Cannot Access Settings

If your PC will not start normally or you cannot open Settings, you can reset from the Windows login screen. Restart your computer and watch for a message that says "Press any key to boot from CD or DVD" or similar — if you see this, ignore it and let Windows load normally. When you reach the login screen, look for a power icon in the bottom right corner.

Click the power icon, hold Shift, and click Restart. Your PC will boot into a blue screen with options. Click Troubleshoot, then Reset this PC, and follow the same steps as above. This method works even if Windows is damaged or will not load properly.

If your PC will not boot at all and you see only a black screen or error messages, you may need to use a Windows installation disc or USB drive. You can create one on another computer by downloading the Windows Media Creation Tool from Microsoft's website, following their instructions to make a bootable USB drive, and then using that drive to reset your original PC. This is more complex and should be your last option.

Preparing Your PC Before the Reset

Before you begin, make a list of the programs you use regularly so you can reinstall them afterward. Write down the names of software you paid for, because you may need your license keys or login information to reinstall them. Free programs like Chrome, Firefox, or VLC can be downloaded again easily, but paid software like Microsoft Office or Adobe Creative Suite requires your account information.

Sign out of any cloud services like OneDrive, Google Drive, or Dropbox before you start. This prevents your files from being deleted from the cloud when your local copies are removed. You can sign back in after the reset is complete.

If you have a second monitor, keyboard, or printer connected, you can leave them plugged in — Windows will recognize them after the reset. However, disconnect any USB drives or external hard drives except the one holding your backup files, to avoid accidentally erasing something important.

What Happens After the Reset Is Complete

When the reset finishes, your PC will restart and show the Windows setup screen, just like a brand-new computer. You will be asked to choose your language, accept the license agreement, and create or sign in with a Microsoft account. If you do not have a Microsoft account, you can create one or set up a local account instead.

After setup, your desktop will be empty except for the Recycle Bin and a few default Windows icons. If you chose "Keep my files," your Documents, Pictures, Music, and Downloads folders will contain your old files, but all your programs will be gone. You will need to reinstall them one by one.

Go to the Microsoft Store or the websites of the programs you use to read and install them again. Sign back into cloud services like OneDrive or Google Drive so your files sync back to your PC. Restore any files from your backup drive. This process usually takes a few hours depending on how many programs you use and how fast your internet connection is.

Common Problems and How to Fix Them

If the reset gets stuck on a loading screen or spinning circle for more than three hours, your PC may have frozen. Wait at least 30 minutes before assuming this — some older computers take a very long time. If you are certain it is frozen, hold the power button for 10 seconds to force a shutdown, then turn it back on and try the reset again.

If you see an error message during the reset, write down the exact text and search for it online along with your Windows version number. Common errors include "The operation could not be completed" or "Reset failed" — these usually mean a hard drive problem or corrupted Windows files. If the reset fails twice, your hard drive may be failing and you may need professional help.

If your PC resets but then will not boot into Windows, it may be stuck in a boot loop. Restart your computer and try the reset again from the login screen method described above. If this does not work, you may need to use a Windows installation USB drive or contact a repair technician.

Frequently Asked Questions

Will a factory reset remove viruses and malware?

A factory reset removes most malware because it deletes all files on your drive and reinstalls Windows fresh. However, some advanced malware can hide in your PC's firmware or BIOS, which a standard reset does not touch. If you suspect a serious infection, run antivirus software before you reset, and consider having a technician check your PC after the reset is complete.

Can I cancel a factory reset once it starts?

You should not cancel a reset once it has begun, because stopping it mid-process can leave your PC in an unusable state. If you need to stop it, wait until your PC restarts and shows the Windows setup screen — at that point you can safely turn it off. If the reset is still running, wait for it to finish rather than forcing a shutdown.

Do I need a Windows product key to reset my PC?

If your PC came with Windows pre-installed, Windows is tied to your hardware and you do not need to enter a product key during the reset. If you installed Windows yourself using a separate license, you may need your product key to reactivate Windows after the reset. Check your email or the documentation that came with your PC to find your key.

How long does a factory reset actually take?

A factory reset usually takes 45 minutes to two hours on a modern PC with a solid-state drive. Older computers with traditional hard drives can take three to four hours. The "Keep my files" option is usually faster than "Remove everything" because it does not need to completely wipe the drive. Do not interrupt the process — let it run to completion even if it seems slow.

What if I reset my PC and forgot to back up my files?

Once a factory reset completes, your files are gone and cannot be recovered through Windows. If the reset just finished and you have not restarted your PC yet, you might be able to recover some files using data recovery software, but this is not may provide. For the future, always back up important files before any major change to your PC.
