Powershell command

get checksum:
Get-FileHash -Algorithm MD5

download a file:
method 1:
$url = "http://mirror.internode.on.net/pub/test/10meg.test"
$output = "$PSScriptRoot\10meg.test"
$start_time = Get-Date

Invoke-WebRequest -Uri $url -OutFile $output
Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

method 2:
$url = "http://mirror.internode.on.net/pub/test/10meg.test"
$output = "$PSScriptRoot\10meg.test"
$start_time = Get-Date

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $output)
#OR
(New-Object System.Net.WebClient).DownloadFile($url, $output)

Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

$client = new-object System.Net.WebClient
$client.DownloadFile("http://www.xyz.net/file.txt","C:\tmp\file.txt")
It works as well with GET queries.

If you need to specify credentials to download the file, add the following line in between:

$client.Credentials = Get-Credential

$computer = gc env:computername

$key = "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX"

$service = get-wmiObject -query "select * from SoftwareLicensingService" -computername $computer

$service.InstallProductKey($key)

$service.RefreshLicenseStatus()
