How to fix error 0x80070005 while installing Windows IoT

The Internet of Things, or IoT, is intended to unify devices, sensors, data, and the cloud. Unlike a computer or tablet, the IoT can access specific hardware such as lights, sensors, and motors. This capability allows you to create fun projects or professional devices.

Microsoft provides an image for installing Windows IoT, which can be downloaded from here. It is typically installed into a storage device, with SD Cards being a common choice. If you download the Windows IoT dashboard, you will receive an .exe file to install said dashboard. This dashboard then allows you to download the OS from the Windows Store and install it onto a storage device. Note that if you encounter the error 0x80070005 while trying to download and install the file from the dashboard, this signifies an access denied error. This error is not exclusive to the installation of this software and may also occur with Windows Updates, Windows Restore Point, and Windows 8/10 apps downloaded from the store, among others.
