The Laptop You Dropped At The Tip Might Still Have Your Bank Details On It

A woman brought a laptop in last month wanting me to transfer her files to a new machine, and the old one was going to the recycling point at the tip. "Don't worry about wiping it," she said, "I've already deleted everything off it." I had a quick look. Her online banking was still logged in, and I found three years of tax returns sitting in a folder marked Old Stuff. Deleting a file just removes the signpost to it - the data itself sits on the drive until something else overwrites it, which on a laptop that's about to be recycled might be never.

Why "I deleted it" doesn't mean it's gone

When you delete a file, or even empty the recycle bin, Windows marks that space on the drive as available to reuse. It doesn't scrub the data. Anyone with basic recovery software - and it's freely available - can pull those files back, especially from a drive that's been sitting idle rather than actively used since. Recycling points and WEEE collection bins are generally set up to reclaim metals and plastics safely, not to check whether your passport scan is still readable off the hard drive.

• Photos and documents recover easily even after deletion.
• Saved passwords in browsers can often be extracted even from a drive that looks "empty" at a glance.
• Old email accounts left signed in are a way into resetting passwords elsewhere.

Doing it properly before the laptop leaves the house

If the laptop still boots, the simplest safe route is a full factory reset. In Windows, go to Settings > System > Recovery > Reset this PC, choose Remove everything, and when it asks about the drive, pick the option to fully clean the drive rather than the quick option - it takes longer but properly overwrites the data rather than just removing the file references. This applies whether it's an SSD or an older mechanical hard drive.

Plenty of the laptops that came in for recycling this year were old Windows 10 machines whose owners finally let them go after support ended back in October 2025. That's a fair reason to move on, but it's exactly the sort of laptop where a full reset matters most, because it's likely been used for years and built up a proper history of logins and documents.

If the laptop won't boot at all, a factory reset isn't possible, and that's when I'd rather remove the drive and either wipe it separately on another machine or physically destroy it. For most people, that means bringing it to someone like me rather than putting a dead laptop straight in a recycling bin as-is.
