Hi DJS195923Jan,
Thank you for the update. You can't download the original operating system from Microsoft or Sony website because the version installed in your laptop is an OEM version. You need a VAIO recovery disc to reinstall the system.
You may refer to the links below to create your own recovery disc:
For computers running Windows 7 and below:
For computers running Windows 8 and the latest version:
If an error occurs while creating a recovery disc then probably the recovery disc is corrupted or already deleted. If so, then you may need to purchase one.
Regards,
Jen
