What a hard reset does and when to use it

A hard reset wipes your PC back to the state it left the factory — all your files, programs, and settings are erased, and Windows reinstalls itself fresh. This is different from a restart, which just turns the computer off and on. Use a hard reset when your PC is so slow or broken that normal fixes won't work, when you're selling or giving away the computer, or when malware has infected it so badly that you don't trust the system anymore.

Before you start, understand that a hard reset destroys everything on your drive. Back up any files you want to keep to an external drive, cloud storage, or another computer first. Once you begin, there is no undo button. The process takes 30 minutes to two hours depending on your PC's speed and which reset method you choose.

Key Takeaways

  • A hard reset erases all files and programs and reinstalls Windows from scratch, so back up anything you want to keep before you start.
  • The easiest method is Settings > System > Recovery > Reset this PC, which works on Windows 10 and 11 without needing a USB drive.
  • If Windows won't start or Settings won't open, boot from a Windows installation USB and reset from there instead.
  • The reset process takes 30 minutes to two hours and will restart your PC multiple times — do not turn it off during this time.
  • After the reset completes, you will need to set up Windows again with a Microsoft account and reinstall your programs.

Reset through Settings if Windows still starts

If your PC boots into Windows and you can open the Settings app, this is the fastest route. Click the Start button (Windows logo in the bottom left), type "Settings" and press Enter. Once Settings opens, click "System" on the left side, then scroll down and click "Recovery."

Under the "Recovery" section, 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 hard reset. On the next screen, choose "Local reinstall" (Windows downloads and installs from your PC) or "Cloud read" (Windows downloads from Microsoft's servers). Local reinstall is faster if your internet is slow. Click "Next," confirm you want to proceed, and Windows will begin the reset. Your PC will restart several times. Do not turn it off or unplug it during this process.

Reset from a Windows installation USB if Windows won't start

If your PC won't boot into Windows or the Settings app won't open, you need a Windows installation USB. You will need another working computer and a USB drive with at least 8 GB of space. On the working computer, go to microsoft.com/software-read/windows11 (for Windows 11) or microsoft.com/software-read/windows10 (for Windows 10). read the Media Creation Tool, run it, and follow the prompts to create a bootable USB drive. This takes 10 to 20 minutes.

Plug the USB drive into the broken PC and restart it. As it boots, press the key that opens the boot menu — this is usually F12, F2, Esc, or Del, depending on your PC's manufacturer. The screen will show which key to press during startup. Select the USB drive from the boot menu. Windows Setup will load. Click "Repair your computer" at the bottom left, then "Troubleshoot," then "Reset this PC." Follow the same steps as above: choose "Remove everything" and let the reset run to completion.

What happens during the reset process

Once you confirm the reset, Windows begins erasing your drive and installing a fresh copy of itself. You will see a progress bar and percentage counter. The PC will restart multiple times — this is normal. Each restart takes a few minutes. The entire process usually takes 45 minutes to two hours depending on your PC's speed and whether you chose local or cloud read.

During the reset, your screen may go black or show "Windows is being installed" messages. Do not turn off the PC, unplug it, or press any keys. If the reset appears to freeze for more than 30 minutes without any change, it may have failed — in that case, force a shutdown by holding the power button for 10 seconds, then try the reset again from the beginning.

Set up Windows after the reset completes

When the reset finishes, your PC will boot into Windows Setup. You will be asked to choose your language, region, and keyboard layout. Then you will create or sign in with a Microsoft account. If you do not have one, you can create one during setup with any email address. Windows will ask whether you want to use recommended privacy settings — you can accept these or customize them. The setup process takes 10 to 15 minutes.

After setup finishes, you will see a blank desktop. Windows is now fresh and clean. You will need to reinstall any programs you use — Microsoft Office, Chrome, Zoom, antivirus software, and anything else. You can read these from their official websites or from the Microsoft Store. Your files are gone unless you backed them up before the reset, so restore them from your backup drive or cloud storage now.

Troubleshooting if the reset fails or gets stuck

If the reset stops responding or shows an error message, force a shutdown by holding the power button for 10 seconds. Wait 30 seconds, then turn the PC back on and try the reset again. If it fails a second time, try the USB method instead — a USB reset is more reliable when the PC is severely damaged.

If you see an error like "There was a problem resetting your PC" or "We couldn't complete the reset," the hard drive may be failing. In that case, the reset cannot complete, and you may need to replace the drive or take the PC to a repair shop. If the reset gets stuck on the same percentage for more than 30 minutes, the drive is likely the problem as well.

Frequently Asked Questions

Will a hard reset remove viruses and malware?

Yes. A hard reset erases the entire drive and reinstalls Windows fresh, which removes all malware, viruses, and unwanted programs. This is one of the most reliable ways to clean a heavily infected PC. After the reset, install antivirus software and avoid downloading files from untrusted sources.

Can I cancel a hard reset once it starts?

Not safely. Once the reset begins erasing your drive, stopping it mid-process can leave your PC unbootable. If you realize you made a mistake, let the reset finish. If it gets stuck, force a shutdown and try again, but do not interrupt it once it is running.

Do I need a product key to reset Windows?

No. If Windows was already activated on your PC before the reset, it will reactivate automatically after the reset completes. If you never activated Windows, you can still use it after the reset, but you will see a watermark on the desktop and some customization options will be locked.

What if I forgot my password before resetting?

A hard reset erases your old password, so you will not need it. When Windows Setup finishes, you will create a new Microsoft account or sign in with a different one. You start fresh with no password history.

How much free space do I need to hard reset?

You need at least 20 GB of free space on your drive for Windows to install. If your drive is nearly full, delete large files or programs before starting the reset. If you cannot free up space, the reset may fail partway through.
