Prior to XP Professional x64 Edition, logic was that special characters such as: `&,<>,()@^` were forbidden in quotes. Quotes must be stripped if any of these characters appear in a parameter. This logic is documented in the cmd.exe documentation at MSDN. However, after XP Professional x64 Edition, Microsoft added the `Program Files (x86)` directory, and it seems like they removed parentheses from the list of forbidden characters in quotes. The documentation doesn't mention it. I have checked that XP Professional SP 2 x32 bit strips quotes when it finds parentheses in a parameter passed with /C, and XP Professional x64 Edition and all versions after it, whether 32 or 64 bit, preserve quotation marks when parentheses are in a parameter. Also, I checked that XP Professional x64 Edition is based already on NT 5.2, same with Windows Server 2003.
