Warning PowerShell ID 300

Question

Warning PowerShell ID 300

Piero 75

Hi,

More than a year after reporting the problem, I continue to receive the same PowerShell warning despite everything working normally and all versions being up to date.

Maybe with this new information we can better understand the problem.

I know it doesn't affect the functioning, but I'm a bit picky...

Thanks for any help.

It's hard to read your image. Can you please post those statements that you are executing so we can test on our machines?

I would also reomment that instead of passing the entire script on the command line that you save it in a .ps1 file and execute that. Also add in a Start-Transcript at the beginning and a Stop-Transcript at the end and have it generate a log file. Then review that for errors.

If you can read that, good for you!

Why do you think the evet is a "Warning"? It looks like it's an "informational" event.

A TEXT copy of the event is preferable to a screenshot.

It looks like you're trying to run powershell script (maybe from a scheduled task) that's trying to use a Microsoft.Update.Session COM object. The powershell session is run with a "restricted" execution policy.

Is the Windows Update Service (wuauserv) running? Does your code produce any output?

MotoX80 37,161

I had my cataracts removed in April.

Displaying the update counts might have some value.

$UpdateSession = New-Object -ComObject 'Microsoft.Update.Session'
$UpdateSearcher = $UpdateSession.CreateUpdateSearcher()
$count = $UpdateSearcher.GetTotalHistoryCount()
Write-Host "We found $count total updates."
$Updates = $UpdateSearcher.QueryHistory(0,$count)
Write-Host "QueryHistory returned $($updates.count) updates."

The above code does not generate a 300 event on my Win11 laptop.

Check your transcript.

So add in the rest of your code. Try to isolate which statement is causing your problem.

The error is "Device not ready" The exception class is IOException. The only explicit "IO" I can see in your code is the use of the "Write-Host".

So, is this being run as a scheduled task? Does the account under which the scheduled task runs have the necessary permission and rights?

The use of the COM object may also be a problem. It has to access your system disk to have access to the data. See the above question about the user account, permissions, and rights.

I'm pretty sure you need administrative rights to use Microsoft.Update.Session. If running from a scheduled task make sure the task is using the "highest rights" option. That account would also need the necessary COM Object Permissions.

MotoX80 37,161

It was able to access Microsoft.Update.Session with a non-admin account.

Run this and examine the transcript. If it is the write-host, then I would expect that you would get several errors.

Start-Transcript -Path 'C:\windows\temp\KB-Test.log'
$Res = 0                   
$look4 = 'KB5030310'
$UpdateSession = New-Object -ComObject 'Microsoft.Update.Session'
$UpdateSearcher = $UpdateSession.CreateUpdateSearcher()
$count = $UpdateSearcher.GetTotalHistoryCount()
Write-Host "We found $count total updates."
if ($Count -ge 1) {
    $Updates = $UpdateSearcher.QueryHistory(0,$count)
    Write-Host "QueryHistory returned $($updates.count) updates."
    $kb = $Updates | Where-Object {$_.Title -match $look4}
    if ($kb -eq $null) {
        Write-Host "We did not find $look4."
    } else {
        Write-Host "We found $look4."
        $Res = 1

You're running different versions.

Your image and the text of the error says "HostVersion=5.1.22621.4111".

But your last post has

Host Application: C:\Program Files\WindowsApps\Microsoft.PowerShell_7.4.5.0_x64__8wekyb3d8bbwe\pwsh.dll Process ID: 11232 PSVersion: 7.4.5

Back to Rich's question; how are you running this script? A scheduled task? Intune? SCCM? Interactively?

Did PS 7.4.5 generate the eventlog record?

Why did you switch from 5.1 to 7.4.5?

What is launching the script?

Why did you change PS versions?

Does PS 7.4.5 also generate the same event that PS 5.1 did?

Are you the network/desktop/server admin who is responsible for managing your environment or are you more of an end user who just happened to see this event and wondered what it was?

Rich Matheisen 48,026

Okay, so it's like to be a scheduled task or, more frightening, there's something in the registry that causes a script to run when a local user logs on here: “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run” or here: “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce”

To check your scheduled tasks, try running this PowerShell script (modify the $outcsv value to use a path of your choice

$taskPath = "\"                     # for example
$outcsv = "c:\junk\taskdef.csv"
Get-ScheduledTask |                 # Without a -taskpath value, it looks in ALL folders
    ForEach-Object { 
        if ($_.Actions.Arguments -like "*Microsoft.Update.*") {
            [pscustomobject]@{
                Name       = $_.TaskName
                Path       = $_.TaskPath
                LastResult = $(($_ | Get-ScheduledTaskInfo).LastTaskResult)
                NextRun    = $(($_ | Get-ScheduledTaskInfo).NextRunTime)
                Status     = $_.State
                Command    = $_.Actions.execute
                Arguments  = $_.Actions.Arguments

Autoruns from sysinternals.com would show all startup entries. But if he's not the admin who developed/administers that script then he really should be talking to his desktop support team.

@MotoX80 They may not know who wrote it either! Stuff like that creeps into the system over time, people forget, or don't want to fess up to the ownership, or any number of other reasons for disavowing any knowledge of the "who" or the "why".

Knowing that it does run was the first step. Discovering how it runs is the second step. Right now, he doesn't even know that! Punishing the innocent will be the last step. :-O

LOL. When my company outsourced the Windows/Unix/Database teams back in 2017, I tried to explain to anyone who would listen that it was a bad idea to throw ALL OF US out on the street, because there was so much institutional knowledge that would be lost. They didn't listen and 5 years later when nothing was getting done and the business units were revolting, they threw out the "3 letter company" who made big promises and had to rebuild their inhouse teams. But hey, thanks for the nice severance package.

Piero 75

Sorry

In fact, the event also occurs when manually starting "Windows PowerShell", from Terminal App not as administrator, while with other versions the problem does not occur.

In app, Terminal there are: Windows PowerShell; Command prompt; PowerShell; and Azure Cloud Shell..

There's no way for us to know what configuration change was made by you or someone/something else on your pc.

I think that the best that we can do is to help you try to isolate the issue. Let's start by NOT using the Terminal app and focus just on Powershell.exe first.

Check your settings and verify that you have Windows Console Host set.

Then open a command prompt and just run powershell. Note that the prompt changes to "PS C:>".

Is that enough to generate a 300 event?

What about this?

powershell "write-host 'Hello';exit"

This is what it means:

You commented "while with other versions the problem does not occur."

In your last post it says "PowerShell 7.4.5".

Your initial question references Powershell 5.1.

Why do you continue to switch versions?

Which versions of Powershell have the problem? 5.1, 7.4.5, or both?

@MotoX80

"$profile" should contain the full path of the current profile. It's just a string value.

I think you meant $PSHOME which would provide the directory name.

I was googling around and found a site that mentioned some NoteProperties that I was not aware of. Since we have no way of knowing what happened on Piero's pc, I thought that it would be good idea to see if any of those files existed and what (if anything) was in them.

$profile $profile.AllUsersAllHosts $profile | gm | Where-Object -Property MemberType -eq NoteProperty | ft -Property Name, Definition

@motox80 You're right. I learned something today!

Also interesting: Powershell with the -noprofile switch still shows a profile:

C:\Users\XXXXX\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

Ditto for pwsh.

There's no such profile file, though.

So, maybe he has no profile files?

I don't know what he has going on. As you pointed out it's an I/O error, but it doesn't indicate which file/cmdlet is causing it. I had hoped that a transcript would show something, but then he ran it with PS7. And he did the same with my request to look for profile files. But the way his comment reads (to me) he only has the problem with PS5.1. So, I do not understand why PS7 is being used at all.

Piero, please reply to my comments dated Sep 23, 2024, 1:58 PM.

This is the output of the command in both versions, however the version that causes problems should be 5.1 which is automatically displayed when the operating system starts.

The thing is that PowerShell versions are automatically installed in the system in Terminal and here I have as per attachment.

Can't uninstall version 5.1??

Thanks

Are you having difficulty understanding what I ask? Maybe try using a different English/Italian translation site. Try Google Translate.

These are the statements that I wanted you to run.

You ran them but with version PS 7.4.5 which you've commented does not have a problem.

If you are having a problem with PS 5.1, then when we ask you to run something, please run it in PS 5.1.

I am going out of town for a few days. Maybe Rich can help you.

Piero 75

Version 5.1 is actually Windows PowerShell.

I try to reinstall the previous version of windows

What do you mean by "version 7.4.5 also no longer works properly"? What specifically does not work?

It appears that KB5043145 has multiple problems. If you installed the "preview", then you might want to uninstall it and wait for the general release of that patch.

https://www.bing.com/search?pglt=41&q=KB5043145

In looking at what you posted, the fact that those files do not exist in either version is OK. That just means that whatever is causing your event ID 300 is somewhere else.

Have you ever used Process Monitor?

I think I see where some of this confusion is coming from. If you have both Windows PowerShell (versions earlier than 6.0), and PowerShell (versions later than 6.0), you may be running PowerShell version 7.x.x when you click on the "Windows PowerShell" icon in the start menu. To verify this, go ahead and use the "start" menu and when the PowerShell window opens, type $PSVERSIONTABLE.PSVersion. Is the "Major" value "5" or "7"?

If it's "5" your profiles are in a different location ("WindowsPowershell") instead of the "PowerShell" subdirectory.

When you have both versions of PowerShell installed it's always a good thing to include the $PSVersiontable.PSVersion output somewhere in your comments.

Just to recap:

The problem occurs only with Windows PowerShell 5.1

The problem doesn't occur when you're logged on as "administrator" and run Windows PowerShell 5.1

The problem does occur when you're logged on as a normal user and start Windows PowerShell 5.1

The problem does not occur when starting PowerShell 7, regardless of the user account you used to log on.

Does the problem occur if, when logged on as a normal user, you use "Run as administrator" to start Windows PowerShell 5.1?

After removing the latest windows update: To recap, the problem occurs randomly when starting the operating system and the one listed is in the event log with id:300, while the error occurs even when manually starting the 5.1 version of Windows PowerShell both as administrator and not! Event View:

"What do you get when you run this in PS 5.1?" I only get the id300 error when I start the app.

My last suggestion is my favorite troubleshooting tool.

https://learn.microsoft.com/en-us/sysinternals/downloads/procmon

Process Monitor will capture a low level trace of all file, network, and registry calls being made on your pc. You will need to analyze the trace and look for something wrong. It will not produce a nice "here is your problem" output. But it will give us a good idea of what Powershell is doing.

If you are willing to share the .pml trace file on Dropbox or some other internet file sharing site, I can take a look at it.

The first thing you want to do is use the Filter menu and add an entry for "process name is powershell.exe".

The 2 key icons are the square box that will start/stop the capture, and the red trash can to clear the trace.

After you have added the filter entry, you will want to do this sequence.

Clear the trace by click in the red trash can icon.

Run powershell to recreate the problem.

Stop the trace by clicking on the square icon.

It should look like this.

Note the record count in the lower left. The count should not be incrementing.

In the Result and Detail columns, look for something that might indicate a "Device not ready" status.

Note that a result of "Access denied" and "NOT FOUND" do not necessarily indicate a problem, but do warrant some attention.

If you can't find anything and can't share the .PML trace file, then my recommendation is to just ignore the event ID 300 errors.

The only unusual I/O exception that I could find is this one.

I traced PS on my Win11 laptop and I see similar I/O. The 3 non-success events, in yellow, match up. But my PS does a QueryEAFile call where yours does not.

I don't know if setting your TEMP environment variable to point to the E: drive is causing this or not. Try putting it back to C: and see if that eliminates the event.

Open a command prompt and test like this.

set temp=c:\windows\temp set tmp=c:\windows\temp powershell.exe "1+1;$env:temp;$env:tmp"

That will temporarily override the variables and point temp back to the C: drive. The result should look like this.

C:\>powershell "1+1;$env:temp;$env:tmp" 2 c:\windows\temp c:\windows\temp

See what that does.

Sorry for the delay in responding, but I didn't notice your intervention, however I followed your instructions from the prompt, but the event is still created at startup and I noticed that the variables remain as I had previously set them...

Any other suggestions?

I didn't ask you to permanently change the variables, just temporarily for one cmd session. The set command only applies to that window. It's not permanent.

Open 2 command prompt windows.

In one of them, copy and paste those 3 statements. Then look in the eventlog to see if it generated a 300 event.

In the second window just paste in a slightly different powershell statement. It should show you that temp points to your E: drive. Then look in the eventlog to see if it generated a 300 event. Which command line did it log? Both 1+1 and 2+2?

I have no idea what your pc is doing. My suggestion at this point is to just ignore those events.

Maybe they will go away at some point.

@MotoX80 Would you post the contents of your $PSVersionTable?

@Piero Would you do the same?

I'm interested in the build number of PS 5.

A few years ago, there was a problem that involved the QueryEAFile call that was resolved in later builds. That probably why it doesn't appear to be a problem in PowerShell 7.

It starts with PowerShell creating a PSScriptPolicyTest file (with additional ornamentation to make the name unique each time). PowerShell then tries to run that file. If it runs, PowerShell assumes that AppLocker is disabled or isn't installed and runs in "Full language" mode. If it fails to run, PowerShell runs in "Constrained" mode.

The original problem was that the file contained only one character: "1". That caused AV software (including MS Defender) to block the file. Later builds of PS changed the contents of the file to something less likely to trigger a reaction from AV software.

If you're using MS Defender you may find "'SuspiciousScriptDrop' malware was prevented" in the errors reported there.

https://github.com/PowerShell/PowerShell/issues/24217

Now, that "IOError" may be caused by the "E:" drive. Is it a USB device? A networked device? If so, it may simply be unavailable (i.e., "asleep"). But there should be an error logged in the System event log that roughly corresponds to the "300" event.

I haven't looked for the PS build that stopped the AV detection problem. But looking for the words PSScriptPolicyTest and QueryEAFile (and maybe AppLocker) might turn it up.

@MotoX80

I think the last PowerShell build that had the problem (or maybe it was the build at which the problem stopped) was19042. That build was released on 1 Sep 2021.

You and I are running 10.0.22621.4249 (release date 24 Jun 2022).

Build 18362 21 May 2019

Build 19042 1 Sep 2021

Build 20000 15 Nov 2021

Build 21000 10 Feb 2022

Build 22000 5 Apr 2022

Build 22621 24 Jun 2022

There's no need to check any patches. This looks to be a problem between PowerShells' way of checking for AppLocker and the AV softwares' objection to the way that check was done. The I/O error may just be the failure induced by the AV blockage of the file.

Since the new way of checking for AppLocker is a file that contains only a comment consisting of a longer set of fixed characters followed by a date/time stamp, the AV no longer sees the check as a malware drop.
