Programmably connect to a WiFi network using a password
Connecting to a wireless network using a password is harder than what you might think, as you need to create a WiFi ‘profile’. The below PowerShell code can do exactly what you need, it creates the WiFi profile, and connects you to the WiFi network automatically. # Fill in mandatory details for the WiFi network $WirelessNetworkSSID = '<WiFi_SSID>' $WirelessNetworkPassword = '<WiFi_password>' $Authentication = 'WPA2PSK' # Could be WPA2 $Encryption = 'AES' # Create the WiFi profile, set the profile to auto connect $WirelessProfile = @' <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1"> <name>{0}</name> <SSIDConfig> <SSID> <name>{0}</name> </SSID> </SSIDConfig> <connectionType>ESS</connectionType> <connectionMode>auto</connectionMode> <MSM> <security> <authEncryption> <authentication>{2}</authentication> <encryption>{3}</encryption>…
Easy tagging of resources in Azure for billing and charge back
Tagging of resources in Azure can be a pain, especially if you have heaps of resources deployed. Tagging is used primarily for billing purposes and tags applied to the resource group are not inherited by the resources in that resource group.

There’s a few of ways you can chargeback to business units by using tags: Download or view your Azure billing invoice and daily usage data Connect to Microsoft Azure Enterprise with Power BI Cloudyn which has…
