Wipe Computer Data

Someone gave you a computer with a working Windows operating system and it still has previous owner’s personal data. You want to make it yours without the owner’s data files, folders, and logon account.

Deleting the personal data using the Windows delete functions is not a true delete. Even emptying the recycle bin, the files are just hidden waiting to be overwritten with new files and/or during hard drive defragging. Computer technicians and even hackers can recover the deleted or perhaps over written data files using file recovery tools.

To permanently delete the data files, you would need to wipe the hard drive. This process would also nuke the Windows operating system.
