User case: How to clear all data from laptop?
How do I remove all personal info from my PC before returning it to the store? I am returning a new laptop to the store and need to remove all my personal info (admin account, files, apps, etc.). I have looked at 'old' info, and it does not seem to be applicable anymore. If I go to 'reset' and choose to uninstall all my personal files, it then asks how I want to reinstall Windows 10. Can someone please advise as to how I accomplish this with a laptop running Windows 10 Home Version 2004 build 19041.867? I need to return it within the next 2 days, so I need this info ASAP. Thank you.
- Question from Microsoft Community
You may want to know how to delete all data from your laptop permanently due to many reasons, such as returning, selling, or donating it. Some users point out that deleting the partition can be useful. However, does deleting a partition really erase data? Since data recovery tools are becoming much more powerful than ever before, your privacy may still be easily accessible after using these techniques. So, here, we will guide you on how to securely and quickly wipe all data on your laptop without damaging your device or hardware.
Does deleting a partition erase data?
Does deleting a partition on your computer erase all the data? No, it does not. When you delete a partition on your hard drive, you remove its drive letter, causing your operating system to view that space as unallocated. This means the system can no longer locate or access the data that was stored there. However, the data itself remains on the hard drive and can be recovered unless it is overwritten by new data.
So what happens when a partition is deleted?
● Erase the saved file (but still retrievable).
● The drive letter is being removed.
● Getting unallocated area.
● Remove a few malware and viruses.
The same situation occurs when you perform a factory reset or format your laptop. That is to say, these 2 methods will not completely remove all your data unless you take other measures like wiping the disk.
