What a factory reset does and when you need one

A factory reset wipes your HP computer back to the state it left the factory — removing all your files, programs, and settings, then reinstalling Windows fresh. It is not the same as restarting. A restart closes and reopens Windows while keeping everything intact. A factory reset erases the entire drive and starts over.

You might need a factory reset if your computer has slowed to a crawl from years of accumulated software, if malware has taken hold and antivirus tools have not removed it, if you are selling or giving away the machine, or if Windows itself has become so corrupted that normal repairs do not work. It is also the nuclear option when nothing else has fixed a persistent problem.

The catch: a factory reset destroys all your personal files unless you back them up first. Windows will ask if you want to keep your files or remove them entirely — choose wisely, because you cannot undo the choice once it starts.

Key Takeaways

  • Back up all your files to an external drive or cloud storage before starting, because a factory reset will delete them if you choose the "remove everything" option.
  • HP computers running Windows 10 or 11 can be reset through Settings > System > Recovery without needing a USB drive or installation disc.
  • The reset process takes 30 minutes to two hours depending on your drive speed and whether you choose to keep or remove files.
  • After the reset completes, you will need to reinstall any programs you use regularly, since the factory reset removes them all.

Back up your files before you start

Before you touch any reset button, move your important files somewhere safe. Plug in an external hard drive or USB stick with enough space, or use a cloud service like OneDrive, Google Drive, or Dropbox. Copy your Documents, Pictures, Desktop, and Downloads folders — these hold most of what people need to keep.

If you have files scattered in other places, search for them now. Open File Explorer, click the search box at the top right, and type the file name or extension (like .xlsx for spreadsheets or .jpg for photos). Drag anything important to your backup location.

Also write down the names and passwords of any programs you pay for or use regularly — Microsoft Office, Adobe Creative Suite, antivirus software, banking apps. You will need to reinstall these after the reset, and some require you to sign in with your original account.

How to factory reset on Windows 10

Open Settings by pressing the Windows key and typing "settings", then press Enter. Click System on the left side, then scroll down and click Recovery.

Under "Reset this PC", click the blue get your free guide button. Windows will ask whether you want to Keep my files or Remove everything. If you backed up your files and want a completely clean slate, choose "Remove everything". If you want to keep your personal files but remove programs and settings, choose "Keep my files".

Next, Windows asks whether to reinstall from your local drive or read a fresh copy. Choose Local reinstall unless your Windows installation is damaged — it is faster and does not require internet. Then click Next, review the summary, and click Reset. Your computer will restart and the process will begin.

How to factory reset on Windows 11

Press the Windows key and type "reset", then click Reset this PC from the search results. Click the blue Reset PC button.

Choose Keep my files or Remove everything — the same choice as Windows 10. Then select Local reinstall for speed, unless Windows is severely corrupted. Review the list of programs that will be removed, click Next, and then Reset. The computer will restart and begin the reset.

What happens during the reset and how long it takes

Once you click Reset, your computer will restart into a blue screen and begin erasing the drive and reinstalling Windows. You will see a progress bar and an estimated time remaining — this is usually accurate within 15 minutes.

The whole process typically takes 30 minutes to two hours. Older computers with traditional hard drives take longer than newer ones with solid-state drives (SSDs). Do not unplug the computer or close the lid during this time, even if it seems stuck. If the progress bar has not moved in over an hour, then something has gone wrong — restart the computer and try again.

When the reset finishes, your computer will restart and ask you to set up Windows as if it were brand new. You will create or sign in with a Microsoft account, choose privacy settings, and set a password. After setup completes, you will see a blank desktop with only the built-in Windows programs.

Reinstalling your programs and restoring your files

Once Windows is set up, plug in your backup drive or sign into your cloud storage and copy your files back to Documents, Pictures, and other folders. This is safe to do when ready — your files will not interfere with the fresh Windows installation.

Then reinstall the programs you use. If you chose "Keep my files" during the reset, some programs may still be listed in Settings > Apps, but they will not work until you reinstall them properly. Go to each program's website or the Microsoft Store, read the installer, and run it. Sign in with your original account if the program requires a license.

Windows Update will also run in the background and read security patches. Let this finish before you do anything else — it can take 20 minutes to an hour depending on how many updates are waiting.

When to call HP support instead of resetting

A factory reset solves most problems, but not all. If your computer will not start at all — no lights, no fan noise, nothing — the problem is likely hardware, not software. If it starts but when ready crashes before you can open Settings, you may not be able to reach the reset screen.

If Windows is so corrupted that you cannot open Settings or Recovery, you will need to create a bootable USB drive with Windows installation media on another computer. This is more complex and usually worth calling HP support for, especially if your computer is still under warranty. HP can also help if the reset fails partway through or if your computer has a custom recovery partition that needs special handling.

Frequently Asked Questions

Will a factory reset remove viruses and malware?

Yes, in most cases. A factory reset erases the entire drive and reinstalls Windows from scratch, which removes nearly all malware. However, some advanced rootkits can survive a reset by hiding in the firmware. If malware returns after a reset, the infection was likely in the BIOS or firmware — contact HP support for a firmware scan.

Can I cancel a factory reset once it starts?

Not safely. Once the reset process begins and starts erasing the drive, stopping it will leave your computer in an unusable state. If you realize mid-reset that you made a mistake, let it finish. You can restore files from your backup afterward.

Do I need the Windows installation disc or product key?

No. HP computers come with Windows pre-installed and a license tied to the hardware. When you choose "Local reinstall", Windows reinstalls from a hidden partition on your drive using that license. You do not need a disc or key.

What if I forgot my Windows password before resetting?

You can still reset the computer. On the sign-in screen, click "I forgot my password" and follow the recovery steps — you can use a backup email or phone number. If you cannot recover the account, you can still start the reset process by restarting the computer and pressing a key combination during startup (usually F11 or Esc, depending on your HP model) to reach the recovery menu.

How much free space do I need to factory reset?

You need at least 10 to 15 GB of free space on your drive for Windows to reinstall. If your drive is nearly full, delete large files or programs you do not use, or connect an external drive to make room. If you cannot free up space, the reset will fail partway through.
