I have a laptop that is infrequently used. When I boot it up it generally wants to update windows 7 Pro and my kaspersky database. I mangaged to brick the operating system during the process of updating - not sure if I did something stupid or not. I did not have proper recovery media so I used the "built-in" recovery tool to reinstall the operating system. I lost data of course and all of the software I used needs to be reinstalled. Here's the thing. When I purchased the laptop I immediately updated (online) the Windows 7 Home Premium version to Windows 7 Pro. The recovery tool restored the laptop operating system to it's default Windows 7 Home Premium version. I decided that I would just upgrade to Windows 10 but have learned since that my upgrade will be to Win 10 Home Premium instead of Win 10 Pro. I wonder if anyone might have an idea how to either restore my default Win 7 Home Premium to Win 7 Pro so that I might be able to upgrade to Win 10 Pro. This is a Toshiba Protege laptop with a registered operating system. Thanks.
