CheckOsVer v1.4.1

描述：CheckOsVer is a simple tool that displays information about the operating system that is installed. The tool simply shows what version of Windows the computer is running, and what service pack has been installed. You can copy the information to the clipboard. It doesn't seem to do anything more.
