           Summary: 3.3.1 Verifying checksums on Windows systems not
                    correct

Description of problem:
Powershell command for getting expected checksum not correct:

$expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern
$image) -split " ")[0].ToLower()

Should be:

$expected_checksum = ((Get-Content $checksum_file | Select-String -Pattern
$image) -split " ")[3].ToLower()

since checksum file content is:

SHA256 (Fedora-Live-Workstation-x86_64-22-3.iso) =
