What resetting Windows means and when you need it
A Windows reset removes your programs, files, and settings and puts your computer back to the state it was in when you first turned it on. You keep your Windows version and license — you are not downgrading or buying anything new. A reset is different from a restart (turning the computer off and on), which just closes open programs and clears temporary memory.
You might reset Windows if your computer is running slowly, crashing often, infected with malware that antivirus software cannot remove, or if you are selling or giving away the machine. A reset can also fix problems where Windows itself is corrupted — when programs won't open, the system won't start, or error messages appear constantly.
Before you reset, back up any files you want to keep. A reset deletes everything on your C: drive (usually your main drive) unless you choose to keep personal files. Once you start the reset, you cannot stop it halfway through.
Key Takeaways
- Windows has two reset options: keep your personal files or remove everything, and both take 30 minutes to several hours depending on your drive speed.
- You can start a reset from Settings on a working computer, or from the Windows recovery screen if your computer won't start normally.
- A reset removes all programs you installed, so you will need to reinstall Microsoft Office, Chrome, Zoom, or any other software you use regularly.
- Your Windows license stays with your computer, so you will not need a product key after the reset completes.
- If your computer will not start at all, you may need to create a Windows installation disk on another computer before you can reset.
Resetting from Settings when Windows starts normally
If your computer starts and you can log in, the fastest reset path is through Settings. Open Settings by pressing the Windows key and typing "settings", then click the Settings app. Go to System in the left menu, then scroll down and click Recovery.
Under "Recovery options", you will see a button labeled Reset this PC. Click it. Windows will ask whether you want to Keep my files or Remove everything. If you choose "Keep my files", Windows removes all programs but leaves your Documents, Pictures, Desktop, and Downloads folders intact. If you choose "Remove everything", the drive is wiped completely — this is the option to use if you are selling the computer or dealing with malware.
After you choose, Windows will show you a list of programs it will remove. Review this list to make sure you are not losing anything you need to reinstall. Then click Next and Reset. The process usually takes 30 minutes to two hours depending on how much is on your drive and how fast your storage is.
Resetting when Windows won't start
If your computer will not start normally or gets stuck on a blue screen, you can reset from the Windows recovery screen. When you turn on the computer, watch for a message that says "Press any key to boot from CD or USB" or similar. If you see this, press a key. If the computer goes straight to an error or blank screen, restart it by holding the power button for 10 seconds, then turn it back on and watch for the boot message.
If you have a Windows installation disk or USB drive, insert it now. If you do not have one, you will need to create one on another computer. Go to microsoft.com/software-read/windows (for Windows 11) or microsoft.com/en-us/software-read/windows10 (for Windows 10), read the Media Creation Tool, and follow the steps to create a bootable USB drive on a working computer.
Once the Windows recovery screen appears, select your language and click Next. Click Repair your computer at the bottom left. Then click Troubleshoot, then Reset this PC. From here, the process is the same as resetting from Settings — choose whether to keep files or remove everything, review the list of programs, and click Reset.
What happens after the reset finishes
When the reset is complete, your computer will restart and show the Windows setup screen, the same screen you saw the first time you turned on the computer. You will need to create a user account (or sign in with an existing Microsoft account), choose privacy settings, and connect to the internet. This takes about 10 to 15 minutes.
After setup finishes, your desktop will be empty except for the Recycle Bin and a few built-in Windows apps like Settings, File Explorer, and Notepad. Any programs you had installed — Microsoft Office, Chrome, Zoom, Slack, or anything else — are gone and must be reinstalled. Your Windows license is still active, so you will not need to enter a product key.
If you chose "Keep my files", your personal files are in their original locations. If you chose "Remove everything", the drive is blank except for Windows itself. Either way, Windows Update will run automatically and read the latest security patches, which may take 15 to 30 minutes.
Reinstalling your programs after reset
After the reset, you will need to reinstall any programs you use regularly. If you have the original installation files or product keys, use those. For programs you downloaded from the internet, go back to the publisher's website and read the latest version.
For Microsoft Office, sign in with your Microsoft account at office.com and click Install Office. For Chrome, go to google.com/chrome and click read Chrome. For most other programs, search the program name plus "read" and go to the official website (not a third-party read site, which may bundle unwanted software).
If you are not sure which programs you had installed, check your email for receipts or license keys, or look through your browser history from before the reset if you saved it to a file.
Keeping your files safe before you reset
If you choose "Keep my files" during reset, Windows keeps your Documents, Pictures, Desktop, and Downloads folders. However, if you choose "Remove everything" or if you have files in other locations, you need to back them up first.
The simplest way is to copy your files to an external drive. Plug in a USB drive or external hard drive, open File Explorer, and drag your important folders to the external drive. This takes a few minutes to an hour depending on how much data you have. You can also upload files to OneDrive, Google Drive, or another cloud service, though this is slower if you have a lot of files.
After the reset is complete, you can copy the files back from the external drive or read them from the cloud service. Do not rely on the cloud backup alone — always have a local copy on an external drive as well.
Troubleshooting reset problems
If the reset starts but gets stuck or shows an error, restart your computer by holding the power button for 10 seconds. Then try the reset again from Settings or the recovery screen. If it fails a second time, the problem may be a failing hard drive or corrupted Windows files that cannot be repaired by a reset.
If you see an error message like "The drive is write-protected" or "Windows cannot complete the reset", try these steps: restart the computer, go back to Settings > Recovery > Reset this PC, and choose "Remove everything" instead of "Keep my files". If that does not work, you may need to create a Windows installation disk on another computer and reset from that disk instead of from Settings.
If the reset completes but Windows will not start afterward, or if you see a message like "Windows could not complete the installation", the installation disk may be corrupted. read the Media Creation Tool again on another computer, create a new USB drive, and try the reset once more.
Frequently Asked Questions
Will I lose my Microsoft Office license if I reset?
No. Your Office license is tied to your Microsoft account, not to the Windows installation. After the reset, sign in with the same Microsoft account at office.com and reinstall Office. Your license will be recognized automatically.
Can I reset Windows if I don't have a product key?
Yes. Your Windows license is stored on your computer's hardware, not on a product key. After the reset, Windows will recognize your license automatically when you sign in with your Microsoft account. You will not need to enter a key.
How long does a reset take?
A reset usually takes 30 minutes to two hours, depending on how much data is on your drive and how fast your storage is. Solid-state drives (SSDs) are faster than older hard drives. The reset will show a progress bar, but it may appear stuck for several minutes — do not restart the computer during this time.
What if I reset and my computer is still slow?
If slowness continues after a reset, the problem may be hardware-related — a failing hard drive, not enough RAM, or an overheating processor. Check your hard drive health using the built-in Windows tool: open Settings, go to System > Storage, and look for "Disk health" or run the command "wmic logicaldisk get name, size, freespace" in Command Prompt to see how much space is free.
Can I undo a reset after it finishes?
No. Once the reset completes, your programs and settings are gone permanently. This is why backing up your files before you reset is important. If you have files on an external drive or in cloud storage, you can restore them after the reset, but programs must be reinstalled from scratch.
