Subject: [PATCH 2/3] Fix Windows downloads directory recognition in
 installer.ps1

- Changed default directory parameter from hardcoded ${HOME}\Downloads to null
- Added Get_Downloads_Dir function to read actual downloads folder from Windows registry
- Modified Set_Install_Dir to auto-detect downloads directory or use current directory
- Updated help text to reflect new default behavior (current directory)
- Removed unused $default_install_dir variable
