Globally Unique Identifiers - Creating GUIDs in Powershell

Powershell Pea...

New-Guid

I've been working more and more with Powershell, specifically with Azure Automation and scripting and wanted to share a useful Cmdlet for creating GUIDs. This link provides more detail, but ultimately this command will provide you with a unique ID that can be assigned to arbitrary objects that require a unique ID.

Bear in mind that this doesn't protect you from duplicates, but the probability of them occurring is small. So if you need GUIDs for relatively small record/object sets and your application can handle the prospect of duplicates, then this function is a quick way to generate a "unique" ID.

See this link for more details on GUIDs/UUIDs.
