    I have two PCs running Widows 10. I want to dispose of both PCs which I have used for emailing etc. I used Gmail and I want to ensure the next person cannot access them by removing access to my account. How do I safely do this?

    I should have said I want to retain my Gmail account for use on another PC. Sorry.

    Gmail is a hosted email solution, meaning nearly all data is stored in the cloud. The best way to revoke access would be to go to your Google Account and select 'Security'. (or follow this link: https://myaccount.google.com/security)

    on that page select "2-step verification" and make sure it is setup. Then at the bottom of that page where it says "Devices you trust" click "REVOKE ALL" this will then force you to use 2FA on all device until you tell google to trust them again. Then follow this link:

    https://myaccount.google.com/device-activity?utm_source=google-account&utm_medium=web

    This will show all of the locations where you are signed in. cick the dots in the top right of each device box you wish t sign out from. Click 'sign out' will force whoever opens gmail on that device to have to reauthenticate to gain access to your mail.

    There may be some data stored in your local cache which could be retrieved so for each of the browsers installed on the PC, you will need to clear those.

    However, there is a much better way to secure your gmail account on that device and any other data you may have on the disks. If you use windows 10 to "ceate a recovery drive" from the control panel on a USB stick for example, you can then reboot into a cmd shell that is hosted on the USB and not the drive. From here you can enter the following command to completely wipe the disk and make any data on it completely unrecoverable: (NOTE: this will render the PC completely useless and the drive will need to be reformatted and windows reinstalled for whoever you give the PC to to be able to use)

    Code:
    Format C: /P:3
    You will need to repeat this for every data drive in the PC replacing 'C:' with the letter of the drive.

    If you want specific instructions on how to do this check out this blog post here.

    For recycling remove the hard drive (or SSD). For gifting, donating or selling provide a clean operating system by installing or "recovery (or reset) to factory defaults."
