How to Reset Windows 10 — Factory Reset, Keep Files, or Full Reinstall (2026 Guide)

How to Reset Windows 10 — Factory Reset, Keep Files, or Full Reinstall (2026 Guide)

Quick Answer

To reset Windows 10: go to Settings (Win+I) > Update & Security > Recovery > Reset this PC > Get Started. Choose "Keep my files" to reinstall Windows while keeping personal files (removes all apps), or "Remove everything" for a complete wipe. The process takes 30–60 minutes. Your PC will restart multiple times — this is normal. Do NOT turn it off during the reset.

A Windows 10 reset is the most powerful fix available for a PC that is crashing, infected with malware, impossibly slow, or simply needs to be wiped clean before you sell or give it away. The good news: you do not need a disc, a product key, or any technical expertise. Microsoft built the reset tool directly into Windows 10 — it is free, reliable, and takes less than an hour in most cases.

This guide covers every method for resetting Windows 10, including what to do when your PC will not boot, when the built-in reset fails, and exactly which option to choose based on your situation. We start with what to back up before you touch anything.

Critical Warning Before You Reset

Even the "Keep my files" option removes ALL installed programs — Microsoft Office, Adobe, browsers, games, everything. Write down every application you use and locate your license keys before starting. Personal files in Documents, Desktop, Downloads, Pictures, and Music are preserved by "Keep my files" — but always back them up anyway. A reset cannot be undone once it begins.

Before You Reset: Backup Checklist

A reset is a one-way operation. Even with "Keep my files" selected, data loss is possible if something unexpected happens mid-process — a power outage, a hardware failure, or a reset that encounters an error. Do not skip this section.

Fastest Backup Method

Plug in a USB drive (8 GB minimum), open File Explorer, and drag your Desktop, Documents, and Downloads folders directly onto the drive. This takes 5–20 minutes and covers 95% of what most users need to preserve. Do this before anything else.

Method 1: Reset via Settings — Keep My Files

1

Reset via Settings > Recovery (Keep My Files)

Recommended Method

This is the right choice for most people. Windows reinstalls itself completely while preserving your personal files in standard folders. All third-party applications are removed, but your documents, photos, music, and downloads remain intact. Use this when your PC is slow, infected with malware, or behaving erratically — and you can still get into Windows.

  • Press Win + I to open Settings. Click Update & Security.
  • In the left panel, click Recovery. Under "Reset this PC," click Get Started.
  • When the dialog appears, select "Keep my files." Windows will show you a list of apps that will be removed — review it carefully.
  • On the next screen, choose "Cloud download" (downloads a fresh Windows 10 copy — requires internet, takes longer but is more reliable) or "Local reinstall" (uses files already on your drive — faster, works offline).
  • Click Next, review the summary screen, then click Reset to begin. Your PC will restart immediately and begin the process.
  • Wait while Windows resets. Your PC will restart 2–4 times during the process — do not turn it off. The screen may stay black for several minutes at a time. This is normal.
  • When setup completes, Windows will prompt you to sign in and walk through a brief setup wizard. Your personal files will be in their original folders.
  • A folder named "Windows.old" may appear on your C: drive containing remnants of the old installation — you can safely delete it via Disk Cleanup once you confirm everything is working.
Expected result: A fresh Windows 10 installation with all your personal files intact. All viruses, corrupted system files, and problematic software are eliminated. Total time: 30–50 minutes on most PCs. Significantly faster on an SSD.

Method 2: Reset via Settings — Remove Everything

2

Reset via Settings > Recovery (Remove Everything)

Complete Clean Wipe

This option wipes everything — your files, applications, and all Windows settings — and installs a completely clean copy of Windows 10. Use it when you are selling or giving away your PC, when a virus has deeply compromised the system, or when you want an absolute fresh start with nothing carried over.

  • Complete the backup checklist above. Everything on this PC will be deleted permanently.
  • Press Win + IUpdate & SecurityRecoveryGet Started.
  • Select "Remove everything."
  • Choose "Cloud download" or "Local reinstall." Cloud download is recommended for the cleanest result if you have a stable internet connection.
  • On the next screen, click "Change settings." You will see a toggle for "Data erasure."
  • If keeping the PC: leave Data erasure Off. Windows deletes your files but does not overwrite them (faster, ~45 minutes).
    If selling or donating: turn Data erasure On. Windows overwrites free space so data cannot be recovered (slower, 2–4 hours, but essential for privacy).
  • Click ConfirmNextReset. The PC will restart and begin the full wipe and reinstall.
  • After the reset, Windows will walk you through initial setup as if it were a brand new PC — choose your region, language, Wi-Fi network, and Microsoft account or local account.
Expected result: A completely clean Windows 10 installation with no trace of previous files, apps, or settings. The PC performs as it did when Windows was first installed. Total time: 45–90 minutes (without data erasure) or 2–4 hours (with data erasure enabled).

Method 3: Reset from Windows Recovery Environment (PC Won't Boot)

Reset from Windows Recovery Environment

When Windows Won't Start

If Windows 10 will not boot at all — it crashes on startup, gets stuck in a restart loop, or shows a blue screen before reaching the desktop — you can access the Reset function through the Windows Recovery Environment (WinRE) without needing a disc or USB drive.

  • Method A (from a working Windows session): Hold Shift and click Start → Power → Restart. Your PC will boot into the recovery environment instead of Windows.
  • Method B (PC won't start at all): Force-restart your PC 3 times in a row by holding the power button during startup. After the third interrupted boot, Windows 10 automatically enters the recovery environment with the message "Preparing Automatic Repair."
  • In the recovery environment, navigate to Troubleshoot → Reset this PC.
  • Choose "Keep my files" or "Remove everything" as described in Methods 1 and 2.
  • Choose "Cloud download" (requires Wi-Fi connection in WinRE — click the network icon in the bottom-right corner to connect) or "Local reinstall."
  • Click Reset and allow the process to complete. Do not interrupt power.
Expected result: Even on a PC that completely refuses to boot, the recovery environment can perform a full reset and restore Windows to a working state. This resolves the vast majority of boot failures caused by corrupted system files or a bad update.

Method 4: Reset using Windows 10 USB Installation Media

Reset using Windows 10 USB Installation Media

When Built-in Reset Fails

When the built-in reset reports an error like "There was a problem resetting your PC" or the recovery environment is inaccessible, a bootable USB drive gives you a fresh copy of Windows 10 from outside the broken installation. You will need a second working PC and an 8 GB or larger USB drive to create the media.

  • On a working PC, go to microsoft.com/software-download/windows10 and click "Download tool now" to get the Media Creation Tool.
  • Run the tool, accept the license, and choose "Create installation media (USB flash drive, DVD, or ISO file) for another PC."
  • Select language, edition (Windows 10), and architecture (64-bit for most PCs). Insert your USB drive and select it as the destination. The tool downloads and writes Windows 10 — this takes 15–40 minutes depending on your internet speed.
  • Insert the USB into the broken PC. Restart it and enter the boot menu by pressing the key shown on startup — typically F12, F8, F9, or Esc depending on your PC brand. Select the USB drive from the boot list.
  • When the Windows Setup screen appears, choose your language settings and click Next, then "Install now."
  • Click "I don't have a product key" — Windows 10 will automatically activate using the digital license tied to your motherboard once installation completes and you connect to the internet.
  • On the "Which type of installation?" screen, select "Custom: Install Windows only (advanced)" for a clean wipe. Select your existing Windows partition, click Next, and allow the installation to complete.
Expected result: A guaranteed clean Windows 10 installation that bypasses any issues with the existing recovery partition. This method works even when the hard drive's recovery tools are completely broken. Your PC activates automatically — no product key required.

Method 5: Run SFC + DISM Before Full Reset (Try This First)

5

System File Repair via Command Prompt (SFC + DISM)

Try Before Resetting

If your Windows 10 problems are caused by corrupted system files rather than a deep infection or hardware issue, two built-in command-line tools can repair them without resetting or reinstalling anything. Try this first — it takes 15–30 minutes and preserves everything on your PC.

  • Click the Start menu, type cmd, right-click Command Prompt, and select "Run as administrator."
  • Type the following command and press Enter: sfc /scannow
    System File Checker will scan all protected Windows files and automatically replace any corrupted ones. This takes 10–20 minutes. Do not close the window.
  • When SFC finishes, run DISM to repair the Windows image itself: DISM /Online /Cleanup-Image /RestoreHealth
    This downloads and replaces damaged Windows component files. Requires an internet connection. Takes 10–20 minutes.
  • After DISM completes, run SFC one more time: sfc /scannow — this allows SFC to fix anything it couldn't repair before DISM restored the source files.
  • Restart your PC and test whether the problem is resolved. If it persists after all three scans, proceed with a full reset using Method 1 or 2.
Expected result: SFC + DISM resolves many issues caused by Windows Update failures, random crashes, and corrupted DLL files without requiring any reset. If the scans report "Windows Resource Protection found corrupt files and repaired them," restart and check whether the symptoms are gone.

Keep My Files vs. Remove Everything: Which to Choose?

The right choice depends entirely on why you are resetting. Here is a direct comparison to help you decide:

Situation Recommendation
PC is slow, crashing, or unstable but data matters Keep My Files
Malware or virus infection — files are important Keep My Files
Selling, donating, or recycling the PC Remove Everything + Data Erasure On
Severe ransomware or rootkit infection Remove Everything
Complete fresh start, no files to keep Remove Everything
Handing to a family member to reuse Remove Everything
Windows won't boot, files backed up Remove Everything
Windows won't boot, files NOT backed up Keep My Files (from WinRE)

Remember: "Keep My Files" Still Removes All Apps

Both options reinstall Windows from scratch. The only difference is what happens to your personal data files. Neither option keeps your installed programs. Microsoft Office, your antivirus, Chrome, Adobe — all of it must be reinstalled. This is why writing down your apps and license keys before the reset is so important.

How Long Does a Windows 10 Reset Take?

Reset time varies significantly based on the method, your storage type, and whether you choose cloud or local reinstall. Here are realistic expectations:

Your PC will appear to "freeze" or sit at a specific percentage for long periods during the reset. Do not panic and do not force-restart unless the progress has been completely static for more than 2 hours with no disk activity. The disk activity light on your PC is a better indicator of work being done than the on-screen percentage.

After the Reset: What to Do First

A freshly reset Windows 10 installation is not fully ready to use. Follow this sequence to get back to a secure, functional state as quickly as possible:

Post-Reset Setup Sequence

Do This in Order
  • Step 1 — Run Windows Update immediately. Go to Settings → Update & Security → Windows Update → Check for updates. A fresh Windows 10 install may be missing months or years of security patches. Install all available updates and restart. Repeat until no updates remain. This may take 30–60 minutes.
  • Step 2 — Install your antivirus. Windows Defender activates automatically and provides solid baseline protection. If you use a third-party antivirus, install it before browsing the web.
  • Step 3 — Install your browser. Open Edge (the default browser after reset), go to chrome.google.com or mozilla.org, and download your preferred browser. Sign in to sync your bookmarks.
  • Step 4 — Update your drivers. Go to Device Manager (right-click Start → Device Manager) and look for any yellow warning triangles. For your graphics card, download the latest driver directly from Intel, AMD, or NVIDIA's website rather than relying on Windows Update.
  • Step 5 — Reinstall your applications. Work through your list of software. Install apps one at a time, restarting when prompted. Activate using your saved license keys.
  • Step 6 — Restore your files. Copy your backed-up files from the external drive back to their original folders. Check that everything is intact before disconnecting the backup drive.
  • Step 7 — Set up Windows Backup. Go to Settings → Update & Security → Backup and configure File History to back up to an external drive automatically. Now that you are starting fresh, this is the perfect time to build a backup habit.

Reset Complete: Your PC Should Feel New

A properly completed Windows 10 reset eliminates nearly all software-based problems: malware, corrupt files, broken updates, performance degradation, and mysterious errors. If significant problems return within a few weeks of a clean reset, the cause is hardware — typically a failing hard drive or overheating components. In that case, contact a technician for a hardware diagnosis.

Frequently Asked Questions

Will resetting Windows 10 remove viruses?
In almost all cases, yes. "Remove everything" performs a complete wipe and reinstall of Windows 10, which eliminates virtually all malware including ransomware, trojans, and rootkits. "Keep my files" also reinstalls Windows but preserves your personal files — it removes most malware but very sophisticated rootkits that embed in firmware or the boot sector may survive. If you suspect a serious infection, always choose "Remove everything" for the cleanest result. After any reset, run a full Windows Defender scan before restoring files from your backup to ensure the backup itself is not carrying infected files.
How long does a Windows 10 reset take?
A Windows 10 reset takes between 30 and 90 minutes depending on the method and your hardware. "Keep my files" typically takes 30–50 minutes on an SSD and 45–70 minutes on a traditional hard drive. "Remove everything" without data erasure takes 45–90 minutes. If you enable data erasure (recommended before selling or donating), expect 2–5 hours. Resetting from a USB drive adds media creation time but the reset itself is similar. Your PC will restart several times during the process — this is completely normal. Do not turn it off.
Can I reset Windows 10 without losing files?
Yes. The "Keep my files" option in Settings → Update & Security → Recovery reinstalls Windows while preserving your personal files in Documents, Downloads, Desktop, Pictures, and Music. However, it removes ALL installed applications and programs — only your personal data files are kept. You will need to reinstall all your software after the reset. Always back up your files to an external drive before resetting regardless of which option you choose, because if the reset encounters a problem mid-process, data recovery may not be possible.
What if the Windows 10 reset gets stuck?
If the reset appears stuck at the same percentage for more than 2 hours, first check the hard drive activity light on your PC. If it is blinking, work is still happening — continue waiting. If there is no disk activity for an extended period, hold the power button for 10 seconds to force a shutdown. Windows 10 is designed to recover from interrupted resets and will typically roll back to the previous state or launch into the recovery environment automatically on next boot. If the built-in reset fails repeatedly with the same error, use Method 4 (USB installation media) — it bypasses the built-in recovery system entirely and provides the most reliable path to a clean installation.
Does resetting Windows 10 fix the Blue Screen of Death?
Yes, a Windows 10 reset fixes Blue Screen of Death errors caused by software issues — including corrupt system files, bad driver installations, failed Windows Updates, and malware. It does not fix BSODs caused by failing hardware such as bad RAM, a dying hard drive, or an overheating CPU. If BSODs continue after a full reset using "Remove everything," the cause is hardware. Run MemTest86 overnight to check your RAM and use CrystalDiskInfo to check your hard drive health. A technician can perform these diagnostics remotely in most cases.
