need help on powershell script

Question

Hello all,

I'm starting to use powershell and i'm trying to get a certain results and i'm sure someone would be able to help me.

i'm using this command to get the Windows10 cd-key : wmic path softwarelicensingservice get OA3xOriginalProductKey

i would like to copy the results of this request and add it to this line : slmgr.vbs -ipk ( insert cd-key here )

i need to find a way to have this process automated

Thanks

Answer 1

Something like this?

(Get-CimInstance -ClassName softwarelicensingservice).OA3xOriginalProductKey | Out-File 'C:\temp\key.txt'    #Fixed
#.....
$key = Get-Content 'C:\temp\key.txt'
cscript.exe C:\Windows\System32\slmgr.vbs -ipk $key 

Answer 2

there is unwanted stuff in the key.txt

This is the first line in the text file : OA3xOriginalProductKey

the info i need ( the actual cd-key ) is typed after that

Answer 3

the only error left is being able to run it as an admin

Answer 4

Well that really isn't an error, and all the user has to do is launch the .bat or .ps1 with "run as administrator".

To do it programmatically is a bit of a challenge due to PS restrictions.

# Save the key to a file 
$key = (Get-CimInstance -ClassName softwarelicensingservice).OA3xOriginalProductKey 
$key
$key | Out-File 'C:\temp\key.txt'

#.....

# Start-Process doesn't like redirection with elevation. 
# Elevate a second Powershell process and have it call the script with redirection. 
$stdout = "$env:temp\stdout.txt"
$stderr = "$env:temp\stderr.txt"
$key = Get-Content 'C:\temp\key.txt'
$cmd = "start-process cscript.exe -argumentlist 'C:\Windows\System32\slmgr.vbs -ipk $key' -nonewwindow -wait -RedirectStandardOutput $stdout -RedirectStandardError $stderr"
Start-Process 'powershell.exe' -argumentlist $cmd -wait -verb runas  
Get-Content $stdout
Get-Content $stderr

Answer 5

Hello SbastienRousseau

Basically you'll need to assign a variable to the next powershell cmdlet to extract the key:

'(Get-WmiObject -query 'select * from SoftwareLicensingService'). OA3xOriginalProductKey'

then use the variable in the cmdlet: Set-WindowsProductKey -ProductKey $yourvariable
