| Windows PowerShell versions 4.0 (with a patch) and 5.x add advanced logging features that can provide additional detail when malware has been run on a system. Ensuring Windows PowerShell 2.0 is not installed as well mitigates against a downgrade attack that evades the advanced logging features of later Windows PowerShell versions. |
