When you're building out a new server and you don't want to deal with all the default IE restrictions just to download Sitecore installation files.

Get-SitecoreInstallation.psm1

function Get-SitecoreInstallation {
	param(
		[string]$Url,
		[string]$UserName,
		[string]$Password,
		[string]$FilePath
	)
	$loginRequest = Invoke-RestMethod -Uri https://dev.sitecore.net/api/authorization -Method Post -ContentType "application/json" -Body "{username: '$UserName', password: '$Password'}" -SessionVariable session -UseBasicParsing
	Invoke-WebRequest -Uri $url -WebSession $session -OutFile $FilePath -UseBasicParsing
}
