So this may be an odd request and maybe I'm going about this all wrong but I also have a unique situation. I have servers that are sometimes cloned and I need to run a script that I created on the clones servers. Due to the nature of the clones they cannot be connected to a network.
Currently I am manually putting the generic script on each server before cloning and then running the script on the clone server.
What I would like to do is have a script that runs and gathers all the information, say installed programs as an example, and generate a custom version of my current script on the servers before they are cloned.
I have both the powershell script that gets the server information and the generic one that makes the changes to the clone but I have not found a way to merge the two or any documentation so I don't know if i am hitting a limitation with this one.
Edit for more explanation and examples. I'm doing this from my phone atm so I dont have an example I can post.
Current I have a script that has a set number of applications to uninstall, registry keys to remove, services to stop ect. In another application I have a list of all the software that we have for each server and I can pull that data for each server. What I need to do is pull the data for each server, and have a script placed on each server that will uninstall just the programs for that server.
Currently the script has to run through every potential software and try to uninstall it and then check the other application to see if there are any additional programs that need to be uninstalled.
Hope this extra info helps.
Thanks.
Stop thinking of it as code.
Use script 1 to export blocks of text into a new file. for example, you might have a configuration that says all Dell servers must have this line of code run:
Set-DELL -attribute1 unmanaged
where on HP, the script would have been
Set-HP -attribute1 unmanaged
on web servers, you want:
set-web -active yes
where if not a web server, you want nothing.. so, your parent script code would look like:
$Dell = "Set-DELL -attribute1 unmanaged"
$HP = "Set-HP -attribute1 unmanaged"
$web = "set-web -active yes"
if (Get-servermake -eq "Dell")
{
$dell | out-file Child.ps1 -append
}
if (Get-servermake -eq "HP")
{
$HP | out-file Child.ps1 -append
}
if (Get-webserver -eq $true)
{
$web | out-file Child.ps1 -append
}
The result is a customized script for the specific server, child.ps1.
Now, you can take this and run with it. You could say add functionality to the child script like "Is it an AD controller", etc.
However, you might be better off having all of this in a single script, and just block off sections that don't apply in an if statement for example.
I'm still not totally sure I understand what your asking. If I've missed the mark, tell me how, and I'll tell you how to tweak this better. (And hopefully obvious is that the Get-whatever is sample code. I don't expect that to be what your using to determine a computer make/model/etc)

When I am running commands or installing software remotely using PowerShell - Invoke-Command etc I would like sometimes to be able to show a message on the remote screen so the user knows something is happening, or when work done etc.
I would like to if possible make this message look as professional as possible, e.g. better than just a standard winform message box if it can be done? perhaps more the style of the Windows 10 ones with coloured background and use of image if possible.
Spent a while googling but most seem to relate to using obsolete methods such as net-send or using msg.exe.
Thanks

So the issue really isnt creating the messagebox itself, its having it show on the users session.
So when you run a command against a system, youre using your creds to run the command therefore it wont show in the users session. You can get around this by running it in the users context using a task scheduler. I have a script that does all this for you but, id hate to recreate the wheel and will have to wait till monday (when im at work) to post it here.
It accepts user input in your sessions that outputs it to a vbs, which then copies it over the message to the users machine, and a task schedule is set to run immediately for the user thats logged in.
edit: The script is this without the task scheduler. I just invoke gwmi win32_computersystem | Select -ExpandProperty username to get the current user logged in and add it to the task.
#Prompt for messge
$strMSG = Read-Host -Prompt "Enter message"
#deleting vbs if it exists
del C:\brief\test.vbs
#creating vbs from scratch so it doesnt override
New-Item C:\brief\test.vbs
#Appending each the values to a seperate line
Add-Content C:\brief\test.vbs 'Set objShell = Wscript.CreateObject("WScript.Shell")'
Add-Content C:\brief\test.vbs "strText = `"$strMSG`""
Add-Content C:\brief\test.vbs 'intButton = objShell.Popup(strText,0,"Computer Support",48)'
#calling on the script
& cscript C:\brief\test.vbs
Found a great solution here which appears on quick testing to work well for displaying a toast notification on a remote machine
https://smsagent.blog/2019/06/11/just-for-fun-send-a-remote-toast-notification/
I am looking to delete highlighted value from registry shown in Picture, where 'standard user' is the user id from which system is logged in. I need power shell script so that I can deploy it in every machine of my organization from backend and this highlighted value gets deleted from every user's system profile.
Assuming you are planning on doing this via GPO I would advise two steps:
1- Create the script file and add it to the Files preference on your GPMC
2- Create a one-time Scheduled Task and run the remote script.
This code should do what you want as long as you adapt the Path to your needs. It will get a list of the Values inside the Key you point it to and match it using the where-object.
(Get-Item -Path HKCU:\SOFTWARE\Microsoft\OneDrive\Accounts\Business1\Tenants\Intune Test').Property | Where-Object{$_ -match 'Test Sync - Documents'} | Remove-Item
Deployment is up to you, please assume this code can be improved and or adapted. This is just the core block you need to achieve what you asked.
I've made a script to automatically change and/or create the default Outlook signature of all the employees in my company.
Technically, it gets the environment variable username where the script is deployed, access to the staff database to get some information regarding this user, then create the 3 different files for the signature by replacing values inside linked docx templates. Quite easy and logical.
After different tests, it is working correctly when you launch the script directly on a computer, either by using Powershell ISE, directly by the CMD or in Visual Studio. But when we tried to deploy it, like it will be, by using SCCM, it can't get any environment variable.
Do any of you have an idea about how to get environment variables in a script when it is deployed by SCCM ?
Here is what I've already tried :
$Name = [Environment]::UserName
$EnvVarUserName = Get-Item Env:\USERNAME
Even stuff like this :
$proc = gwmi win32_process -Filter "Name = 'explorer.exe'"
$report = #()
ForEach ($p in $proc)
{
$temp = "" | Select User
$temp.user = ($p.GetOwner()).User
$report += $temp
}
Thanks in advance and have a nice day y'all !
[EDIT]:
I've found a way of doing this, not the best one, but it works. I get the name of the machine, check the DB where when a laptop is connected to our network it stores the user id and the machine, then get the info in the staff DB.
I will still check for Matt's idea which is pretty interesting and, in a way, more accurate.
Thank you all !
How are you calling the environmental variable? $Env:computernamehas worked for me in scripts pushed out via SCCM before.
Why don't you enumerate the "%SystemDrive%\Users" folder, exclude certain built-in accounts, and handle them all in one batch?
To use the UserName environment variable the script would have to run as the logged-in user, which also implies that all of your users have at least read access to your staff database, which, at least in our environment, would be a big no-no.
We have a program running on about 400 PCs (All W7). This program is called Wisa.
We receive regular updates for this program, named something like wisa_update1.0.exe, wisa_update1.1.exe, wisa_update2.0.exe, etc. The users can not do the update themself due to account restrictions.
We manage to do the update once and distribute it with a copy-item to all PCs. Then with Enter-PSSession I can go to each PC and update the program with the following command:
wisa_update3.0 /verysilent
(with the argument /verysilent no questions are asked)
This is already a major gain in time, but I want to do the update more automatically.
I have a file "pc.txt" with all 400 PCs in it. I use this file already for the Copy-Item via Get-Content. Now I want to use this file to do the updates with the above command, but I can't find a good way to use a remote executable with a parameter in PowerShell.
What you want to do is load get-content -Path $PClist and then run your script actions in a foreach. You'll want to adapt this example to your own script:
$PClist = 'c:\pc.txt'
$aComputers = Get-Content -Path $PClist
foreach ($Computer in $aComputers)
{
code actions to perform
}
Also you can use multithreading and get it over with fraction of time (provided you have a good machine). The below mentioned link explains how to do it well.

I am using PSUnit for testing purposes in Powershell 2.0. Because my tests need to connect to a database server I would like to be able to pass the server and database name into the test script. This would then allow developers to run the test scripts on their local machine with a local database while at the same time making it possible to run it on a server. The database may also change depending on the environment.
The PSUnit.Run script doesn't seem to allow you to include parameters with the test script name. Have I missed anything? Is there a workaround for this?
Thanks!
The only way that I was able to find to do this was to include tags at the start of my test script, then search and replace the correct values in place of those tags. For example, in my case my test script included this code at the top of the script:
[string]$ServerName=<ServerName>
[string]$TargetDatabaseName=<TargetDatabaseName>
That is the literal code. Then, in my script where I called the tests I included this code:
foreach ($testPSScript in Get-ChildItem "$testScriptDir\*.ps1") {
(Get-Content $testPSScript.FullName) |
ForEach-Object {$_ -replace "<ServerName>", "'$ServerName'"} |
ForEach-Object {$_ -replace "<TargetDatabaseName>", "'$DatabaseName'"} |
Set-Content $testPSScript.FullName -Force
PSUnit.Run.ps1 -PSUnitTestFile "$testPSScript"
}
You have to remember to overwrite your test script(s) with the original version each time, otherwise it will include the values that you used in your last run instead of the tags and you won't be able to change the values.
Why don't you just include the 2 variables ([string]$ServerName & [string]$TargetDatabaseName) in 'profile.ps1' file & use these in your test cases. These would be available there and you can configure them anytime in the ps1 file.
This seems to be easier & more intuitive than writing a separate script for this task.
Just append any such info to PowerShell profile.
