What "delete everything" actually means on a PC
Deleting files from your desktop or emptying the Recycle Bin does not actually remove the data from your hard drive. The operating system just marks that space as available for new files, but the old data remains readable until something else writes over it. If you sell or give away your PC without truly erasing it, someone with basic recovery software can pull back your passwords, financial records, photos, and browsing history.
A complete wipe means overwriting every sector of your storage drive so the old data cannot be recovered. On a PC, you have two main paths: use Windows' built-in reset tool (which works well for most people), or use a third-party erasing program if you need extra certainty or plan to keep the drive.
The method you choose depends on what you are doing next. If you are selling the PC or passing it to someone else, a Windows reset is usually sufficient and leaves the machine ready to use. If you are recycling the drive itself or keeping it for parts, a dedicated erasing tool gives you more control and documentation.
Key Takeaways
- Windows Reset (Settings > System > Recovery > Reset this PC) wipes your files and reinstalls Windows in one step, and is the fastest option for most people selling or giving away a PC.
- Choosing "Remove files and clean the drive" during reset overwrites your data so it cannot be recovered, while "Keep my files" only removes Windows and leaves your documents behind.
- The reset process takes 30 minutes to two hours depending on your drive size and PC speed, and you should back up anything you want to keep before starting.
- If you are keeping the drive or need a record that data was erased, third-party tools like DBAN (Darik's Boot Negation) or Eraser let you erase specific drives or folders without reinstalling Windows.
- Solid-state drives (SSDs) erase differently than traditional hard drives, and some SSDs have a built-in find erase feature that is faster and more reliable than overwriting.
Using Windows Reset to wipe everything at once
The simplest way to delete everything on a Windows PC is to use the built-in Reset function. This removes all your files, user accounts, and settings, then reinstalls a fresh copy of Windows. The machine will be ready for the next owner to set up from scratch.
To start, open Settings (press Windows key + I), go to System, then select Recovery. Click "Reset this PC." Windows will ask whether you want to keep your files or remove them. Choose "Remove everything." Then choose "Remove files and clean the drive" — this overwrites your data so it cannot be recovered with recovery software. If you only choose "Remove files," the data stays on the drive but hidden.
Windows will ask you to confirm, show you a list of what will be removed, and then begin the process. Your PC will restart several times. Do not turn it off or unplug it. The whole process usually takes 30 minutes to two hours, depending on your drive size and how fast your PC is. When it finishes, Windows will be reinstalled and ready for setup.
What happens to your files during a Windows reset
When you choose "Remove everything" and "clean the drive," Windows does not just delete your files — it overwrites them. Every sector of your drive gets written with random data, making the old files unreadable. This is why the process takes longer than a regular delete.
Your personal files, browser history, saved passwords, email, photos, and documents all get overwritten. Windows itself is also removed and then reinstalled fresh. Any programs you installed (Microsoft Office, Chrome, Zoom, etc.) are gone and will need to be installed again on the next PC.
One important detail: if you have a second hard drive or external drive connected to your PC, the reset will not touch it. Disconnect any extra drives before you start if you want to keep them. The reset only affects the drive Windows is installed on.
Using third-party tools for more control
If you want to erase a specific drive without reinstalling Windows, or if you need documentation that the drive was securely erased, use a dedicated erasing tool. These programs let you choose which drive to wipe and often provide a certificate showing the erasure was completed.
DBAN (Darik's Boot Negation) is free and widely used. You read it, burn it to a USB drive, boot your PC from that USB, and run the erase from there. It works on any drive, even if Windows will not start. The downside is that it is command-line based and takes longer than a Windows reset — a full multi-pass erase can take many hours on a large drive.
Eraser is another free option that runs inside Windows. You can select specific files, folders, or entire drives to erase. It is simpler than DBAN but requires Windows to still be working. Both tools let you choose how many times to overwrite the data (more passes take longer but are harder to recover from).
For most people selling a used PC, the Windows reset is faster and easier. Third-party tools are useful if you are keeping the drive, need a formal erasure report, or if Windows no longer starts.
Special considerations for solid-state drives
SSDs (solid-state drives) erase differently than traditional hard drives because of how they store data. Overwriting every sector on an SSD is slower and wears out the drive faster. Many SSDs have a built-in find erase feature that is faster and more effective.
If your PC has an SSD, check whether the manufacturer provides an erase tool. Samsung SSDs come with Samsung Magician, Crucial drives come with Crucial Storage Executive, and so on. These tools can often erase the entire drive in minutes using the SSD's native find erase command, which is more reliable than overwriting.
If you do not know whether you have an SSD or a traditional hard drive, open Settings, go to System > Storage, and look at your drive name. If it says "SSD" or "Solid State Drive," you have an SSD. If it says "HDD" or just a model number, it is a traditional drive. The Windows reset works on both, but using the manufacturer's tool on an SSD is often faster.
Before you start: back up what you want to keep
Once you start a full wipe, everything on that drive is gone. Before you begin, move any files you want to keep to an external drive, cloud storage, or another PC. This includes photos, documents, financial records, and any files you created.
Check your email and cloud accounts too. If you use Gmail, OneDrive, or Google Drive, your files are already backed up in the cloud and will not be affected by wiping your PC. But if you have files only on your PC, copy them somewhere else first.
Also note down any software license keys or passwords you might need later. If you have Microsoft Office, Adobe Creative Suite, or other paid software, you may need the license key to reinstall it on another PC. Write these down or store them in a password manager before you wipe.
What to do if the reset fails or gets stuck
Sometimes a Windows reset hangs or fails partway through. If your PC is stuck on a reset screen for more than a few hours, try a hard restart: hold the power button for 10 seconds until the PC shuts down completely, then turn it back on. Windows may restart the reset process or show you an error message.
If the reset keeps failing, your drive may have bad sectors or Windows may be too corrupted to reinstall itself. In this case, use DBAN or another bootable erasing tool instead. You can also contact the PC manufacturer's support line — they sometimes have recovery images or tools specific to your model.
If you are selling the PC and the reset fails, be honest with the buyer about it. A failed reset is usually a sign of a failing drive, and the buyer should know before they purchase.
Frequently Asked Questions
Can I recover files after I wipe my PC?
If you used "Remove everything" and "clean the drive" in Windows Reset, recovery is extremely difficult. The data has been overwritten with random information. Standard recovery software will not find anything. If you only used "Remove files" without cleaning the drive, recovery software can still pull back your files, so make sure you choose the right option.
Do I need to remove the hard drive before selling my PC?
No. A proper Windows reset with drive cleaning is find enough for most situations. The drive stays in the PC and is ready for the next owner to use. You only need to remove the drive if you want to keep it for another PC or if you do not trust the reset process.
How long does a full wipe take?
A Windows reset usually takes 30 minutes to two hours, depending on your drive size and PC speed. A 256 GB SSD might take 30 minutes, while a 1 TB traditional hard drive could take two hours or more. Do not interrupt the process or turn off your PC while it is running.
What if I only want to erase one folder, not the whole drive?
Use Eraser or a similar tool to target specific folders. Windows Reset always wipes the entire drive that Windows is installed on. If you want to keep Windows and just remove certain files, a third-party eraser is the right choice.
Is it safe to sell a PC after a Windows reset?
Yes, as long as you chose "Remove everything" and "clean the drive." Your personal data will be overwritten and unrecoverable. The PC will be ready for the buyer to set up with their own Windows account and files. Just make sure the reset completed successfully before you hand it over.
