    • Right-click on PowerShell and select "Run as Administrator" if administrative privileges are required.

  2. Execute the Script:

    • Navigate to the folder containing the script and run it by typing: 
      .\CSR.ps1
      Replace scriptName.ps1 with the actual script filename.

  3. Provide Computer Name:

    • When prompted, enter the name of the computer for which you are generating the CSR. If no name is provided, the script will use the name stored in the COMPUTERNAME environment variable.
