I want to login to a website with powershell commands in windows with following code:
$username = "hansmueller#test.com"
$password = "test_21"
$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true
$ie.Navigate("http://testsite.test")
While ($ie.Busy -eq $true) {Start-Sleep -Seconds 3;}
$usernamefield = $ie.document.getElementById('name')
$usernamefield.value = $username
$passwordfield = $ie.document.getElementById('pw')
$passwordfield.value = $password
It opens the website but doesnt login and gives me the error:

In Windows 11, using PowerShell, I am trying to unpin Microsoft Store from the taskbar and ESPN & Spotify from the start menu.
function unpin_taskbar([string]$appname) {
((New-Object -Com Shell.Application).NameSpace('shell:::{4234d49b-0245-4df3-b780-3893943456e1}').Items() |
Where-Object{$_.Name -eq $appname}).Verbs() | Where-Object{$_.Name.replace('&','') -match 'Unpin from taskbar'} | ForEach-Object{$_.DoIt()}
}
function unpin_startmenu([string]$appname) {
((New-Object -Com Shell.Application).NameSpace('shell:::{4234d49b-0245-4df3-b780-3893943456e1}').Items() |
Where-Object{$_.Name -eq $appname}).Verbs() | Where-Object{$_.Name.replace('&','') -match 'Unpin from Start'} | ForEach-Object{$_.DoIt()}
}
foreach ($taskbarapp in 'Microsoft Store') {
Write-Host unpinning $taskbarapp
unpin_taskbar("$taskbarapp")
}
foreach ($startmenuapp in 'ESPN', 'Spotify') {
Write-Host unpinning $startmenuapp
unpin_startmenu("$startmenuapp")
}
Microsoft Store is unpinned successfully, but the next two fail. This is the output.
unpinning Microsoft Store
unpinning ESPN

What I'm I doing wrong here?
are you looking at something like this by any change?
Install-Module -Name Microsoft.PowerShell.StartMenu
Import-Module Microsoft.PowerShell.StartMenu
Remove-StartAppsTaskbarPinned -AppName "Microsoft Store"
Remove-StartAppsStartMenuPinned -AppName "ESPN"
Remove-StartAppsStartMenuPinned -AppName "Spotify"
You will need to install the module "Microsoft.PowerShell.StartMenu", this is mandatory to run those commands.
You can look at the powershell gallery to find out more what this is about and how it works.
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')"

I am getting this error when executing the below script. Output for the same is also mentioned. I did check for error but dint find any fix.

If your mail address is not valid, you will never get the Password field, but an error message.
For me it is working.
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

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

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?
