如何判断操作系统是windows 7
前几天你给的那个判断操作系统的代码很好！很详细！但就是无法判断windows 7，能否麻烦你修改一下，也适用于windows 7?非常感谢！

一般都是用API GetVersionEx
windows 7还没有正式版，还没稳定，有可能有变化，当前不需要过多考虑。
The GetVersionEx function obtains extended information about the version of the operating system that is currently running.
To obtain information for the operating system on a remote computer, use the NetWkstaGetInfo function, the Win32_OperatingSystem WMI class, or the OperatingSystem property of the IADsComputer interface.
To compare the current system version to a required version, use the VerifyVersionInfo function instead of using GetVersionEx to perform the comparison yourself.
BOOL GetVersionEx(
LPOSVERSIONINFO lpVersionInfo
);
Parameters
lpVersionInfo
[in, out] Pointer to an OSVERSIONINFO data structure that the function fills with operating system version information.
Before calling the GetVersionEx function, set the dwOSVersionInfoSize member of this structure to sizeof(OSVERSIONINFO).
Windows NT 4.0 SP6 and later: This member can be a pointer to an OSVERSIONINFOEX structure. Set the dwOSVersionInfoSize member to sizeof(OSVERSIONINFOEX) to identify the structure type.
Return Values
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero. To get extended error information, call GetLastError. The function fails if you specify an invalid value for the dwOSVersionInfoSize member of the OSVERSIONINFO or OSVERSIONINFOEX structure.
Remarks
Identifying the current operating system is usually not the best way to determine whether a particular operating system feature is present. This is because the operating system may have had new features added in a redistributable DLL. Rather than using GetVersionEx to determine the operating system platform or version number, test for the presence of the feature itself. For more information, see Operating System Version.
To verify whether the current operating system is either Windows XP Media Center Edition or Tablet PC Edition, use the GetSystemMetrics function.
Example Code [C++]
When using the GetVersionEx function to determine whether your application is running on a particular version of the operating system, check for version numbers that are greater than or equal to the desired version numbers. This ensures that the test succeeds for later versions of the operating system. For example, if your application requires Windows XP, use the following test.
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
GetVersionEx (&osvi);
bIsWindowsXPorLater =
( (osvi.dwMajorVersion > 5) ||
( (osvi.dwMajorVersion == 5) && (osvi.dwMinorVersion >= 1) );

那天回答完那个问题，我就改写好了，支持Windows 7(版本号为6.1)。呵呵。
