DAC (Dynamic Access Control) is a new authorization model that greatly simplifies management of access to information resources. 

With DAC, Microsoft introduces Attribute Based Access Control (ABAC) natively in the operating system which gives companies the ability to define policies that control access to files based on their business value and risk by utilizing the classification of the data and properties of users or devices in determining access.

In a recent class, I pointed out to students some of my favorite scripting sources, and found that some students had found one or two, but not all my favorites. So, since PowerShell is all about finding the right script, here are my top five websites for PowerShell scripts. And, by the way, the right script might be the one that does exactly what you need, or it could be the one that does something very close to what you need, and you can modify.
These scripts are not in ranked order, in that the first is the _very_ best, instead, I’ll put them down as they come to me.

Microsoft added a new way to access File History in Windows 10. Windows 10's File History is an easy way to get started with backing up your personal files. The feature takes snapshots of versions of your files and stores them on an external hard drive.

Over time, you build up a library of past versions that you can recover if need be. Say, for example, you really liked a sentence from the first version of a document, but you deleted it long ago and are now battling with regret.

You can dip into File History, retrieve the right version of your document, and copy the sentence.
