Why Your PC Won't Reset and How to Fix It

What's stopping your reset and what to try first

A PC that won't reset usually gets stuck because of a corrupted Windows file, a full hard drive, a broken USB recovery drive, or a problem with your user account permissions. Before you assume the reset is permanently broken, try these steps in order: restart your computer in Safe Mode, free up at least 10 gigabytes of space on your C: drive, and disable any antivirus software temporarily while the reset runs.

If you're trying to reset Windows 10 or Windows 11 using Settings > System > Recovery > Reset this PC, the process often stalls at 0%, 1%, or somewhere in the middle. This usually means Windows can't read its own system files, not that your hardware is failing. Most resets that fail can be completed using a different method.

Key Takeaways

A stuck reset usually means corrupted system files or a full drive, not a broken computer—try freeing space and restarting in Safe Mode before trying again.
If the built-in reset tool won't work, use the Windows Media Creation Tool to make a bootable USB drive and reset from there instead.
Antivirus software, Windows Defender, and third-party security tools can block the reset process, so disable them before starting.
If you see an error code like 0x80070005 or 0xC1900101, write it down and search Microsoft's support site for that specific code—each one has a known fix.

Free up space on your C: drive

Windows needs at least 10 gigabytes of free space to reset. If your C: drive is nearly full, the reset will fail partway through. Open File Explorer, right-click your C: drive, and select Properties to see how much space is left.

If you have less than 10 gigabytes free, delete old files, empty your Downloads folder, and run Disk Cleanup. To open Disk Cleanup, press Windows key + R, type cleanmgr, and press Enter. Select your C: drive, check the boxes for Temporary files, Recycle Bin, and Old Windows installations, then click Delete Files. This often frees several gigabytes without losing anything you need.

If you still don't have 10 gigabytes free after cleanup, move large files to an external drive or cloud storage before attempting the reset again.

Disable antivirus and security software

Windows Defender, Norton, McAfee, Kaspersky, and other security programs can interfere with the reset process by blocking system file changes. Before you start a reset, disable your antivirus software completely—not just pause it.

For Windows Defender, press Windows key + I to open Settings, go to Privacy & Security > Virus & threat protection, click Manage settings, and toggle off Real-time protection. For third-party antivirus, open the program itself and look for a Disable or Turn Off option in the main menu. Restart your computer after disabling, then try the reset again.

Re-enable your antivirus as soon as the reset finishes. Leaving it off permanently leaves your computer unprotected.

Use Safe Mode to attempt the reset

Safe Mode loads Windows with only essential drivers and services, which can help the reset process complete when it fails in normal mode. To restart in Safe Mode, press Windows key + R, type msconfig, and press Enter. Go to the Boot tab, check the Safe boot box, select Minimal, and click OK. Your computer will restart in Safe Mode.

Once in Safe Mode, go to Settings > System > Recovery > Reset this PC and try the reset again. If it succeeds, Windows will restart normally. If it still fails, restart msconfig, uncheck Safe boot, and try the next method.

Create a bootable USB and reset from there

If the built-in reset tool won't work no matter what you try, you can reset Windows using a bootable USB drive. You'll need a working computer (a friend's or family member's) and a USB drive with at least 8 gigabytes of space.

On the working computer, go to microsoft.com/software-read/windows11 (or windows10 if you're running Windows 10). Click read now under Windows 11 Installation Media. Run the downloaded file, select Create installation media for another PC, and follow the prompts to write Windows to your USB drive. This takes 10 to 20 minutes.

Plug the USB drive into your stuck PC, restart it, and press F12, F2, Esc, or Del repeatedly as it boots (the key varies by manufacturer—watch for a message on the startup screen). Select your USB drive from the boot menu. Windows Setup will load. Click Repair your computer, then Troubleshoot, then Reset this PC. This method bypasses the corrupted files on your hard drive and usually succeeds when the normal reset fails.

Check for specific error codes

If your reset shows an error code like 0x80070005, 0xC1900101, 0x80070070, or 0x8007025D, the code itself tells you what went wrong. Write down the full code and search for it on support.microsoft.com—Microsoft documents the cause and fix for each one.

Common codes include 0x80070005 (permission denied—usually fixed by running as administrator), 0xC1900101 (incompatible driver or software—uninstall recent programs before resetting), and 0x80070070 (not enough disk space—delete more files). Each code has a specific solution, so searching for the exact number is faster than guessing.

When to back up your files before resetting

A reset removes all your programs and personal files by default, though Windows offers a Keep my files option that preserves documents, photos, and downloads. If you choose Keep my files, your personal data stays but Windows reinstalls from scratch.

Before you reset, back up anything you absolutely cannot lose to an external drive or cloud storage like OneDrive or Google Drive. This takes 30 minutes to an hour depending on how much data you have, but it's faster than recovering files after a failed reset. Once your backup is complete, you can reset with confidence.

Frequently Asked Questions

What does it mean if my reset is stuck at 0%?

A reset stuck at 0% usually means Windows can't read the system files it needs to begin the reset. Restart your computer, free up hard drive space, disable antivirus, and try again. If it still stalls, use the bootable USB method instead—it bypasses the corrupted files.

Can I reset my PC if I forgot my password?

Yes. If you're locked out, restart your computer and press Windows key + R on the login screen to open Run. Type netplwiz and press Enter to open the user accounts panel, where you can create a new administrator account or reset your password. Once you're logged in, you can reset Windows normally.

Will resetting delete my files?

By default, yes—a reset removes all programs and personal files. However, Windows offers a Keep my files option during the reset process that preserves your documents, photos, and downloads while reinstalling Windows. Choose this option if you want to keep your data.

How long should a PC reset take?

A normal reset takes 20 to 45 minutes depending on your hard drive speed and how much data you have. If your reset is still running after two hours, it's likely stuck. Restart your computer and try a different method, like the bootable USB approach.

What if I see a blue screen during the reset?

A blue screen (BSOD) during reset usually means a driver conflict or corrupted system file. Restart your computer, disable antivirus and third-party software, and try the reset in Safe Mode. If that doesn't work, use the bootable USB method, which loads fresh drivers from the installation media.
