I saw a comment on Twitter today about a limitation in PowerShell. Specifically the ability to grant the logon as a service right to a user account. Manually, if you use the Services management console and specify the user, Windows will automatically grant that right. But if you are trying to do this from a…

Convert Text to Object with PowerShell and Regular Expressions
A few weeks ago I was getting more familiar with named captures in regular expressions. With a named capture, you can give your matches meaningful names which makes it easier to access specific captures. The capture is done by prefixing your regular expression pattern with a name. PS C:\> “UNC is \\server01\public” -match “\\\\(?<servername>\w+)\\(?<sharename>\w+)” True…
Friday Fun: Messagebox Writer
For today’s fun I’m revisiting a topic I’m sure I’ve written about in the past and that is creating a graphical message box in PowerShell. There are a few ways you can do this from using the Visual Basic classes, the old standard WScript.Shell object from VBScript or using WinForms. They all basically work the…
Creating CIM Scripts without Scripting
When Windows 8 and Windows Server 2012 came out, along with PowerShell 3.0, we got our hands on some terrific technology in the form of the CIM cmdlets. Actually, we got much more than people realize. One of the reasons there was a big bump in the number of shipping modules and cmdlets was CDXML….
Friday Fun with REST, Regex and Replacements
I just love using the web cmdlets that were introduced in PowerShell 3.0. One of the cmdlets I use the most is Invoke-RESTMethod. This isn’t because I’m dealing with sites that offer REST-ful services, but rather I like that the cmdlet does all the heavy lifting for me when I point it to an RSS…
PowerShell Deep Dive First Sales
Last year I had the pleasure of editing PowerShell Deep Dives, published by Manning. This book is a community project with chapters contributed from MVPs and leading members of the PowerShell community. You won’t find this content anywhere else. Anyway, I have the first royalty report from Q3 2013. Looks like we sold a little…
Updated PowerShell Script Profiler
Last year I wrote a sidebar for the Scripting Guy, Ed Wilson and an update to his PowerShell Best Practices book. I wrote a script using the new parser in PowerShell 3.0 to that would analyze a script and prepare a report showing what commands it would run, necessary parameters, and anything that might pose…
Friday Fun: Does Anyone Really Know What Time It Is?
In PowerShell it is brain-dead easy to get the date and time with Get-Date. If you look through articles I’ve posted you’ll find plenty of examples using Get-Date and the [DateTime] object. But now that we’re getting ready for a new year, I thought you might be planning ahead and might want a few shortcuts…
Friday Fun: A Christmas Present for You
Over the years a number of people in the PowerShell community have shared Christmas and holiday related items. I’ve collected them and in some cases tweaked a little bit. This year I decided to wrap them all up in a module for you. This will work in PowerShell 2.0 and later. #requires -version 2.0 <#…
PowerShell Clean Up Tools
A few years ago I think I posted some PowerShell clean up tools. These were functions designed to help clear out old files, especially for folders like TEMP. Recently I decided to upgrade them to at least PowerShell 3.0 to take advantage of v3 cmdlets and features. I use these periodically to clean out my…
More PowerShell Trace Window Fun
On my last Friday Fun, I posted an article about using Internet Explorer as a trace window. The idea was to put debug or trace messages in a separate application. I received a comment on the post that suggested I could do a similar thing using the Debug View utility from Sysinternals. This application is…
Friday Fun: Create a PowerShell Trace Window
Way back in the day, it was all VBScript and HTAs for me. I built a number of HTA tools for other people to use. As you might expect they didn’t always work and troubleshooting something I couldn’t see was difficult. So I came up with a solution to use an Internet Explorer window as…
Friday Fun: 50 Shades of PowerShell HTML Reports
I’ve been working on a project for a client that includes creating an HTML report, generated by PowerShell. I originally thought I would include a certain feature but decided against it. However, this is so cool I thought I’d share it with you as a Friday Fun article. I’ve done alot this year with some…
Managing Local Admin with PowerShell
Years ago when I was deep into VBScript and HTAs, I wrote a tool called PWDMan. It was an HTA that processed a list of computers and returned password age information for the local administrator account. It was also capable of setting a new account password. Apparently this is still a common task because I’ll…
Out with the Windows.old
Over the last few days I’ve started the process of upgrading my test virtual machines to Windows Server 2012 R2, or in the case of my mini Hyper-V server, to the final bits of Windows Hyper-V Server 2012 R2. In many cases I had been running the preview bits. I know I probably should have…
