Learn about Windows PowerShell
Summary: The easiest way to deploy a Windows PowerShell script to users is to create a Group Policy logon script.
Microsoft Scripting Guy Ed Wilson here. Oh…my eyes feel like they are glued to my eyelids. I am not a night owl, unlike the female who inhabits the house in Charlotte, who seems to enjoy howling at the moon on a regular basis. Anyway, I do like to read, and I found a fascinating book about Shakespeare for American readers at the library yesterday, and as soon as I began reading it, I felt compelled to finish it. Now it seems I must pay for my indulgence.
I received an email from one of my friends in Monterrey, Mexico, who was asking about running a script on his workstations to empty the recycle bin. I told him the best way to do this would be to configure either a logon or logoff script via Group Policy. I was in Monterrey several years ago and have taught VBScript, WMI, and Windows PowerShell workshops down there. It is a great town with excellent cuisine. Whenever I think of Monterrey, I am reminded of the Cerro de la Silla, which is shown in this photo I took during my last visit.
I woke up this morning with a plan. I wanted to configure the Get-ProcessStartUpTimes.ps1 script I wrote last week in a Weekend Scripter article to run on every computer on my network each time a user logs onto the network. In addition, because the Windows Search index service that exists in Windows 7 does not exist on servers, I need to ensure that the script does not run when someone logs onto a server.
To do this, I decided to create a new Group Policy object (GPO) and link it to my nwtraders.com domain in my forest. In the Group Policy Management Editor, I right-click the domain, and then click Create a GPO in this domain. This is shown in the following image.
Right-clicking the newly created GPO in the Group Policy Management Console and clicking Edit opens the Group Policy Management Editor, which is shown in the following image. Because I am interested in tracking not only processes that start after the user logs onto the computer but also processes that start before the logon screen, I configure a logon script for the user. There are startup and shutdown scripts that can be configured in Group Policy that are assigned at the computer configuration level, but they would not be the best place to obtain the information I’m looking for. To set a user logon script, open the User Configuration node of the Group Policy Editor, click Windows Settings and then click Scripts (Logon/Logoff).
I double-click Logon in the right side of the pane, and click the PowerShell Scripts tab as shown in the following image.
From here, I click Add, and click Browse. The Add a Script dialog appears. The Browse button opens a Windows Explorer window that is centered on the SysVol share for my domain. The cool thing is this is a great way to copy the script to the SysVol share, and I drag and drop my Get-ProcessStartUpTimes.ps1 script into the Logon script folder.
Because I do not want the script to run on my servers, I need to create a WMI filter. To do this, I right-click the WMI Filters node in the Group Policy Management Console and click New. The dialog appears that is shown in the following image. After adding my WMI query (tested using the Get-WMIObject cmdlet), I click Save.
The last thing I do is go to the AuditProcessStartUp GPO that I had created, and select the FilterWorkstation WMI filter I created.
Well, that is it. The GPO is now created, and I need to allow it to replicate among my various domain controllers. Tomorrow, I will create a Windows PowerShell script to connect to the network share and to parse the process objects.

how do i make a powershell script execute on a windows 2008 server? i dont have the powershell tab on the logon script properties window?
Do you need to change the Execution Policy to run these scripts?
Wmi Filters are extremely low in many situations. I'll just tak adavantage of them in a very few cases.
I am dealing with the deployment side of this issue. I need to change the ForegroundLockTimeout setting to zero in order for my application to run properly on a user's machine. I assumed that there was functionality in Windows (7 and 2008 R2) where I could programatically get the machine to run a script on logon (must be a t logon since it is a HKCU setting).
After hitting my head against the keyboard looking on the internets for the last several hours - it amazes me that there is no pointy-clicky way to do this.
I meant to say that there is only a pointy clicky ways to do this. That doesn't work for an installkit.
This is off the top of my head and you've probably already considered this, but why wouldn't you call a script from the Startup folder or, even better, the Run key in the Registry, HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run or RunOnce.
Without using gpedit.msc, would like to add power shell script to logon / logoff events in windows 7. Is it possible? If so, how?
