Selling or Giving Away Your PC? How to Erase Your Data for Good with O&O SafeErase
In this guide
About to sell, give away or scrap your PC or an old drive? Careful: deleting your files and emptying the Recycle Bin isn’t enough. With a free recovery program, anyone could find your photos, documents, saved passwords and banking details. Here’s how to erase everything for good and get the computer ready for its new owner.
The short version
- Make a backup of your files and sign out of your accounts.
- Wipe the drive securely with O&O SafeErase, which overwrites the data so it can no longer be recovered.
- Do a clean reinstall of Windows if you want to sell the PC ready to use.
Why “delete” isn’t enough
When you delete a file, Windows doesn’t really erase it: it just marks the space as free. The file stays on the drive until it gets overwritten, and that’s exactly how data recovery programs work. Even a quick format leaves the data readable. To make it unrecoverable, you have to overwrite it, and that’s what a secure erase program does.
Before you wipe: the checklist
- Backup: copy your photos, documents and important files to an external drive or the cloud.
- Sign out of your accounts: browsers (Chrome, Edge, Firefox), email apps, Dropbox, OneDrive, Steam and the like.
- Remove the PC from the device list in your Microsoft, Apple or Google account.
- Deactivate the licences of programs that require it (for example Adobe or some antiviruses), so you can use them on your new PC.
- If you use BitLocker, make sure you have the recovery key if you’ll need the drive in the future.
Guide: wiping your PC with O&O SafeErase
Follow the steps with the Next button. The screens are simplified: names may differ slightly depending on the version.
Open O&O SafeErase
Install O&O SafeErase, activate it with the code you received by email and open it. On the main screen you’ll find the different wiping modes.
Choose what to wipe: to sell the PC, the whole computer
Choose the wiping method
The method decides how many times the data is overwritten. For home use, a method with 1–3 passes is enough. If the drive is an SSD, choose the method made for SSDs: it’s faster and doesn’t wear out the drive for no reason.
Select the right method for your drive
Confirm the wipe
To wipe the whole computer, SafeErase sets up a special boot: the PC restarts and wipes the drive Windows is on. There’s no going back from here.
Check the selected drive and confirm
Wait for it to finish
How long it takes depends on the size of the drive and the method: from a few minutes for an SSD to a few hours for a large drive with several passes. Don’t turn off the PC.
Leave the PC on and plugged in
Keep the report
At the end, SafeErase creates a deletion report: it’s proof that the data has been destroyed, useful if you sell the PC or return it to a company.
Save the report to a USB stick

What if I only want to delete some files?
SafeErase can also securely delete individual files and folders (for example scans of ID documents) and free space, meaning the leftovers of files deleted in the past, without touching Windows or your programs.
After the wipe
- If you’re selling the PC, reinstall Windows from a USB stick made with Microsoft’s official tool: if the PC came with Windows preinstalled, it reactivates by itself.
- If you’re only selling the drive, you can leave it empty: the buyer will initialise it.
Frequently asked questions
Isn’t a Windows reset enough?
“Reset this PC” with the Clean the drive option overwrites the data and already gives you good protection. SafeErase gives you more control: certified methods, wiping of individual drives and a final report.
Does it damage the SSD?
No, as long as you use the method optimised for SSDs. Methods with lots of passes, on the other hand, aren’t needed on SSDs and just wear them out.
Can I use it on USB sticks and external drives too?
Yes: choose Drive and select the external drive or USB stick you want to wipe.
