Goal: Trying to find the Windows 10 license key, display it in a window as well as automatically copy it to the clipboard.
Issue: My output always results in spaces at the beginning and end of the string. I have tried trim(), trimstart(), etc. Nothing has worked thus far. I would not mind so much by the spaces are then saved with the key to the clipboard - making the functionality kinda useless, or at least tedious.
I laid out some notations in the code to identify the problem.
The code (result is below as well):
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
[void][reflection.assembly]::Load("System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")
#Obtain Windows 10 Key
$License = wmic path SoftwareLicensingService get OA3xOriginalProductKey
# FAULT - Used to trim key
$Result = $License.Trim("OA3xOriginalProductKey")
#Used to isolate the spaces in the result. Attempt to see if the spaces occur after the trim, or during the trim.
#The spaces are within the "|" rather than outside of the "|" - meaning that the Trim() is not working properly.
#PLEASE HELP!
$Result = "|" + $Result.Trim() + "|"
#Used to copy key to clipboard
$Result | clip.exe
$form = New-Object System.Windows.Forms.Form
$form.Text = "KeySniffer 1.0"
$form.Size = New-Object System.Drawing.Size(280,140)
$form.StartPosition = "CenterScreen"
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Point(30,70)
$OKButton.Size = New-Object System.Drawing.Size(60,23)
$OKButton.Text = "OK"
$OKButton.DialogResult = [System.Windows.Forms.DialogResult]::OK
$form.AcceptButton = $OKButton
$form.Controls.Add($OKButton)
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,20)
$label.Size = New-Object System.Drawing.Size(280,20)
$label.Text = "Key has been copied to clipboard"
$form.Controls.Add($label)
$textBox = New-Object System.Windows.Forms.TextBox
#Put a trim here as a desperate swing in the dark
#The "-" indicate that the spaces occur within the "$Result"
$textBox.Text = "-" + $Result.Trim() + "-"
$textBox.Location = New-Object System.Drawing.Point(10,40)
$textBox.Size = New-Object System.Drawing.Size(200,20)
$form.Controls.Add($textBox)
$form.Topmost = $True
$form.Add_Shown({$textBox.Select()})
$result = $form.ShowDialog()
if ($result -eq [System.Windows.Forms.DialogResult]::OK)
{
$x = $textBox.Text
$x
}
The result:
-| ****-*****-*****-*****-***** |-
Seems you already took out text you don't want with this
$Result = $License.Trim("OA3xOriginalProductKey")
Now let's try only keep content we want on top of it by design a pattern, that only keeps numbers, upper case chars, and "-". Also, we need to remove extra lines.
$pattern = '[^0-9A-Z-]'
$Result = ($Result -replace $pattern, '').trim() -ne ""
Now you can check out the result, everything unwanted should be gone
$Result = "|" + $Result + "|"
