There are some online courses available in Microsoft Virtual Academy , here an example: Getting Started with Microsoft PowerShell This Microsoft PowerShell course is designed to teach busy IT professionals, admins, and help desk personnel about how to use PowerShell to improve management capabilities, automate redundant tasks, and manage the environment in scale.

All modern Microsoft OS use Powershell. That in mind, make sure your coding to the lowest version of PS you have deployed. I am never going back to VBScript. Never again. I spent years scripting in vbs.. And I haven't looked back. Not only is powershell simple and powerful, but it also integrates with the command shell environment which means flexibile integration with a variety of command shell based admin tools.
Mainly because who wants to spend more time programming anything in two different languages, to have the same result. I find it ironic that one of these points tells you to use VBS to get Powershell. When you're using another language to install another one, you know you have problems in your development methodologies.
Clicking on the HTA brings up a window prompting for login id, first name, last name, and a drop down for company name. It will then create home directory with default folders and also populate other AD fields. My main question is, can I have a PowerShell that will create a window that will prompt for multiple inputs and return error messages to the window, without having any additional software installed?
If you can, can you point me in the right direction? I've not done it, but you can do HTAs in powershell. Best I can point you towards is to google for 'powershell hta'. I think that most of the powershell folks just prompt from the shell and use out-gridview to select a choice. I don't know that I've ever seen a PowerShell script run faster than a vbScript. It's usually a struggle to get a PowerShell script to run close to the speed of vbScript.
But that's balanced out by the fact that I can develop a PowerShell script in about a 10th of the time as I could a vbScript--and since they pay me by the hour that matters : I don't really care if a report script runs 1 minute or 10 at 6am in the morning!!
But I disagree there's no value in updating a working script. Sometimes there very much is. Sometimes it's enough to review a script and ask the question of whether you really need this function any more. And don't forget that you need to set everything up for your replacement and as time goes on the of people who can support vbScript never that high to begin with will dwindle.
Besides, there's few things in life as satisfying as taking a line vbScript and getting it down to lines of PowerShell! DirectorySearcher class. The PropertiesToLoad method was used to specify that just the distinguishedName attribute is being retrieved. The script was slower if this method was not used. This script makes 75 queries of Active Directory to retrieve the 75 names. Notice that you specify the attribute values to be retrieved, and you can turn on paging, specify a timeout value, and disable caching.
The syntax required is not intuitive, but it works and is fast. DirectorySearcher class, except that a single query is constructed to retrieve all 75 Distinguished Names at once. As expected, this is more efficient. As expected, this is faster. This is the fasted method, but it has the drawback that if even one sAMAccountName is not found in Active Directory, an error is raised and no names are converted.
Both of these programs query all groups in Active Directory, and their direct memberships, to find all instances of circular nested groups. The time required, not counting the time required to output the results, were compared on two computers, one relatively fast and the other slower.
The average time in seconds, plus or minus one standard deviation, after 5 trials, 15 minutes apart, is tabulated below. Next, we compare the programs PSLastLogon. Both of these programs query every Domain Controller in the domain for the largest latest value of the lastLogon attribute for all users in the domain. They contain code that can be executed within Windows or Internet Explorer via the Windows-based script host Wscript.
The danger: These scripts are and ideal format for hiding viruses or other malware. If all else fails, you can also enable file extensions in windows explorer and manually edit the filename within the folder.
NET VB. NET is a general-purpose programming language that works in the. NET environment. Visual Studio includes a compiler and other tools for this language. VBS is a unique kind of virus which creates Autorun. VBS virus executes every time the directories are accessed. VBS viruses are difficult to remove. This virus can harm your computer with the help of malicious web pages.
