Access denied on a script that should work - windows

I have an assignment that says: "Find out how many .bat and .cmd files there are on the C drive".
I got help from a classmate, and together we came to this:
Get-Childitem -path c:\ -include *.bat,*.cmd -Recurse -ErrorAction SilentlyContinue|Measure-Object|select count
It works on his computer, but not on mine. And when I only check for .bat files it can work. And it doesn't work by putting *.bat and *.cmd in quotations

Active Directory Member Of Custom Pull Script

I put together this script over 5 years ago now and since have forgotten what I did or how I did it...
For some context, the below script which runs from a .bat file was used to enter a user's display name and then using dsquery and dsget, along with Get-Content from PowerShell commands. About 6 months ago this script stopped working and just crashes and fails with a brief error that it getting stuck on this line to my understanding:
dsquery user forestroot -name "%lookforuser%">"%userprofile%\Desktop\usertemp.txt"
The %lookforuser% variable is set earlier in the script, see below for full source code:
#echo off
title Get AD Groups For User
set /p lookforuser=Enter Username (Surname, Firstname):
set lookforuser2=%lookforuser: =%
echo %lookforuser%
echo %lookforuser2%
dsquery user forestroot -name "%lookforuser%">"%userprofile%\Desktop\usertemp.txt"
set /p usercn=<"%userprofile%\Desktop\usertemp.txt"
dsget user %usercn% -memberof>"%userprofile%\Desktop\usertemp.txt"
Powershell -Command "(Get-Content %userprofile%\Desktop\usertemp.txt) -replace '\"CN=','' ^| Out-File -encoding ASCII %userprofile%\Desktop\usertemp.txt"
Powershell -Command "(Get-Content %userprofile%\Desktop\usertemp.txt) -replace ',OU=','*' | Out-File -encoding ASCII %userprofile%\Desktop\usertemp.txt"
for /f "delims=*, tokens=1" %%A IN (%userprofile%\Desktop\usertemp.txt) do echo %%A>>"%userprofile%\Desktop\%lookforuser2%.txt"
del "%userprofile%\Desktop\usertemp.txt"
Long story short, can anyone help me figure out what's gone on, has my parent company changed something to force this not to work, or has MS changed something that no longer allows this script to run, really stumped and not sure.
Any help would be greatly appreciated, even if you have something similar that works in Powershell

How do I download a file using windows command line without having to input a proxy password?

After looking at various stackoverflow questions, I found several ways to download a file from a command line without interaction from the user.
The only one that worked for me also works only on Windows 10 natively :
curl -sko %TEMP%\file.txt "https://some.hostname/file.txt"
But installing an external tool like wget/curl is what I want to avoid.
What didn't work for me because of proxy errors :
Command:
bitsadmin.exe /transfer "dljob" "https://some.hostname/file.txt" %TEMP%\file.txt
Error:

Refer to this question Access web using Powershell and Proxy
You can try something like that in Powershell and suppose that you have already created a folder named as C:\Test:
$url = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"
$file = "C:\Test\" + $url.Split("/")[-1]
$wb = New-Object System.Net.WebClient
$wb.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials
$wb.DownloadFile($url,$file)
EDIT : 14/08/2020 #17:08
I tried this on Windows Powershell ISE and it works 5/5 :
cls
$start_time = Get-Date
$url = "https://cdn2.unrealengine.com/Fortnite%2FBoogieDown_GIF-1f2be97208316867da7d3cf5217c2486da3c2fe6.gif"
$Folder = "$Env:Temp\DownloadFolder"
# We create a SubFolder Named "DownloadFolder" in the temporary file %Temp% if it doesn't exists yet !
If ((Test-Path -Path $Folder) -eq 0) { New-Item -Path $Folder -ItemType Directory | Out-Null }
# We can get the name of the file to be downloaded from the variable $url
# $url = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"
# In our case the FileName will be = "googlelogo_color_272x92dp.png" or
# Fortnite%2FBoogieDown_GIF-1f2be97208316867da7d3cf5217c2486da3c2fe6.gif
$file = $Folder+ "\" + $url.Split("/")[-1]
Try
{
$wb = New-Object System.Net.WebClient
$wb.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials
$wb.DownloadFile($url,$file)
# better use Invoke-Item $Folder instead of ii
Invoke-Item $Folder
Write-Output "Running Script Time taken is : $((Get-Date).Subtract($start_time).Milliseconds) millisecond(s)"
}
Catch
{
Write-Host "Error from $url" `n"Message: [$($_.Exception.Message)"] -ForegroundColor Red -BackgroundColor DarkBlue
}
This worked for me :
powershell -Command "[System.Net.WebRequest]::DefaultWebProxy = [System.Net.WebRequest]::GetSystemWebProxy(); [System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials; (New-Object Net.WebClient).DownloadFile('https://some.hostname/file.txt', 'file.txt')"

Get file version from .exe URL-Source in PowerShell

I know how to get productversion of a file on my windows PC with powershell
(get-item -Path
'(get-item -Path 'C:\test.exe').VersionInfo.ProductVersion
but is it also possible to get the productversion from a exe file with it's URL?
(get-item -Path 'example.com/test.exe').VersionInfo.ProductVersion
No, it is not possible to get the product version from a URL.
When we use a URL it is not the direct path to access the storage server. Therefore we can not determine the version. By C path we can not access the URL Path.
I tried the shell command for Teamviewer setup URL Teamviewer version 9.X. It is not possible to get it through the URL.
PS C:\Users\israr ahmad> (get-item -Path 'download.teamviewer.com/full').VersionInfo.ProductVersion
get-item : Cannot find path 'C:\Users\israr ahmad\download.teamviewer.com\full' because it does not exist.

powershell behavior when host file handle is closed

I'm looking for an explanation (preferably documentation) of the following madness.
Say I have the following simple Perl script:
use strict;
use warnings;
my $output = "C:\\Temp\\aout.txt";
my $outpute = "C:\\Temp\\aoute.txt";
my $command = "powershell C:\\test.ps1";
close STDOUT;
close STDERR;
if ( (my $pid = fork()) == 0 ) {
open (STDOUT,">>$output") or die "cannot open $output as stdout: $!";
open (STDERR,">>$outpute") or die "cannot open $outpute as stderr: $!";
exec $command or die "couldn't exec $command: $!";
} else {
my $ret = waitpid($pid,0);
}
And that the Powershell script contains:
write-output "yay1";
write-error "nay2";
write-output "yay3";
write-error "nay4";
write-output "yay5";
write-error "nay6";
write-output "yay7";
write-error "nay8";
write-host "done!";
If I run the Perl script, it produces two files, as expected, with the following output:
aout.txt:
yay1
yay3
yay5
yay7
done!
aoute.txt:
C:\test.ps1 : nay2
At line:1 char:41
+ C:\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
C:\test.ps1 : nay4
At line:1 char:41
+ C:\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
C:\test.ps1 : nay6
At line:1 char:41
+ C:\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
C:\test.ps1 : nay8
At line:1 char:41
+ C:\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
If I modify the Perl script to keep STDERR closed before executing Powershell:
use strict;
use warnings;
my $output = "C:\\Temp\\aout.txt";
my $command = "powershell C:\\test.ps1";
close STDOUT;
close STDERR;
if ( (my $pid = fork()) == 0 ) {
open (STDOUT,">>$output") or die "cannot open $output as stdout: $!";
exec $command or die "couldn't exec $command: $!";
} else {
my $ret = waitpid($pid,0);
}
Then it produces one STDOUT file with all of the output:
yay1
C:\\test.ps1 : nay2
At line:1 char:41
+ C:\\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
yay3
C:\\test.ps1 : nay4
At line:1 char:41
+ C:\\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
yay5
C:\\test.ps1 : nay6
At line:1 char:41
+ C:\\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
yay7
C:\\test.ps1 : nay8
At line:1 char:41
+ C:\\test.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,test.ps1
done!
Is Powershell really realizing that STDERR is closed, and is doing a clean redirect onto STDOUT? Or is it the command line console? Or is it Perl?

powershell 2.0 command line redirection

I'm looking for an explanation of the following discrepancy:
Given the following powershell script foo.ps1:
write-host "normal"
write-error "error"
write-host "yay"
Running it with
C:\>powershell .\foo.ps1 > out.txt 2>&1
Produces:
normal
C:\foo.ps1 : error
At line:1 char:10
+ .\foo.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,foo.ps1
Write-Host : The OS handle's position is not what FileStream expected. Do not use a handle simultaneously in one FileStream and in Win32 co
de or another FileStream. This may cause data loss.
At C:\foo.ps1:3 char:11
+ write-host <<<< "yay"
+ CategoryInfo : NotSpecified: (:) [Write-Host], IOException
+ FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.WriteHostCommand
But running with:
C:\>powershell .\foo.ps1 2>&1 > out.txt
Produces (correctly):
normal
C:\foo.ps1 : error
At line:1 char:10
+ .\foo.ps1 <<<<
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,foo.ps1
yay
I almost resolved myself into thinking that the order of the redirection mattered in Windows, however all of the examples in the TechNet usage page for command redirection show the file redirection preceding the stderr redirection.
Can someone please explain this to me?
For reference, this is being done on Server 2003 x64 SP2 with:
C:\>powershell get-host
Name : ConsoleHost
Version : 2.0
InstanceId : 53c90e87-ded1-44f9-8e8d-6baaa1335420
UI : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture : en-US
CurrentUICulture : en-US
PrivateData : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
IsRunspacePushed : False
Runspace : System.Management.Automation.Runspaces.LocalRunspace
and using write-output produces the same result.
(This question is related to my work in solving this.)
That looks like a bug in PowerShell 2.0. I tried reproducing with the PowerShell 3.0 preview and it now works as expected.
