How to fix error 0x80070005 while installing Windows IoT

The Internet of Things or IoT is intended to bring devices together, but also sensors, data and the cloud. The IoT is different from a computer or tablet because it can access specific hardware like lights, sensors, motors. This will allow you to build fun project or professional devices.

Microsoft provides an image to install Windows IoT which can be downloaded here and it’s basically installed into a storage device (very common to see SD Cards.) If you download the Windows IoT dashboard, you will get an .exe file which will install the dashboard. The dashboard will allow you to download the OS from the Windows Store, and also install it onto a storage device. If while trying to download and install the file from the dashboard you get the error 0x80070005 then you are getting an access denied error.
