    Ensure the Remote Registry Service is disabled to block remote access to the Windows registry. Allowing remote registry access can lead to unauthorized changes and pose a serious security risk.
  impact: |
    If the Remote Registry Service is enabled, attackers with administrative privileges could remotely access and modify registry settings, heightening the risk of system compromise.
  remediation: |
    Disable the Remote Registry Service by setting its startup type to "Disabled" (Start value = 4) using one of the following methods:
    - Registry Editor: Navigate to
       - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteRegistry and set the Start value to 4.
        - Services Console: Locate the Remote Registry service, set its startup type to "Disabled", and stop the service.
