Here is story about Gerald:
Gerald was an early adopter of PowerBI at his organisation. He installed the Personal Gateway on his laptop about a year ago to demonstrate how data and files could be integrated into PowerBI Service. Things were great.
Months later, the organisation installed an Enterprise Gateway which made life even betterer.
Gerald's laptop got replaced with a shiny new Windows10 machine, so the Personal Gateway went offline. The PowerBI Service keeps reminding Gerald that his Personal Gateway is offline whenever he wanted to configure datasets to refresh.
Gerald can't uninstall the Personal Gateway and he doesn't want to install another one.
He spent ages searching through the community to find a solution, but found only confusing and outdated information.
He is getting pretty frustrated by the effort he has to go to get support and the undocumented agony that the MS developers are subjecting him to.
