A question came up about piping between advanced functions. The input to the second function might be an array. To illustrate how this works imagine a function that gets disk information ““ or better still use this one.
My test environment usually has a dozen or so machines at any one time. Some of these are short lived and used for a particular piece of testing ““ others are kept for years. I decided that I wanted to keep up to date on the patching of these virtual machines so installed WSUS on a Windows 2012 box.
One issue is that if a VM isn”™t started for 10 days WSUS starts complaining that it hasn"™t been contacted and if you run the WSUS clean up wizard the non-reporting servers may be removed. Checking the WSUS console for which machines haven"™t sync"™d recently is a chore.
Ok the embarrassing moral of this story is that you shouldn’t answer questions in a hurry at the end of the evening. 5 minutes after shutting down I realised that there is a far, far simpler way to get the info. Win32_AccountSID is a WMI linking class. It links Win32_SystemAccount and Win32_SID classes.
`Use the wmi type accelerator with the path from the Element and you can just select the data you want. As a bonus you can discover if the account is local or not

One of the new features in PowerShell v3 is the capability to update the help files. In fact you have to do this because PowerShell v3 doesn"™t ship with any help files. Since Windows 8 RTM"™d there have been a succession of new help files released.
I discovered one of my netbooks didn"™t have the latest version of the help files installed. So I needed to update them. This got me thinking that it would be better if the machine did this for me.
