1. The issue was that: INI parser's List.IndexOf on duplicate sections yields negative range length for List.GetRange, causing ArgumentOutOfRangeException.
2. Fixed issue where WindowsIniService was not handling duplicate section names correctly.
3. Changed the way section line indexes are retrieved to handle duplicate section names.
4. Added a check to ensure that the count of lines in a section is greater than 0.
