我所知道的最好的方法是检查是否从某些DLL导出特定的API.每个新的Windows版本都添加了新功能,通过检查这些功能的存在,可以判断运行应用程序的操作系统.例如,Vista 从kernel32.dll 导出GetLocaleInfoEx,而之前的Windowses没有.
简而言之,这里有一个这样的列表,只包含来自kernel32.dll的导出.
> *function: implemented in* > GetLocaleInfoEx: Vista > GetLargePageMinimum: Vista, Server 2003 GetDLLDirectory: Vista, Server 2003, XP SP1 GetNativeSystemInfo: Vista, Server 2003, XP SP1, XP ReplaceFile: Vista, Server 2003, XP SP1, XP, 2000 OpenThread: Vista, Server 2003, XP SP1, XP, 2000, ME GetThreadPriorityBoost: Vista, Server 2003, XP SP1, XP, 2000, NT 4 IsDebuggerPresent: Vista, Server 2003, XP SP1, XP, 2000, ME, NT 4, 98 GetDiskFreeSpaceEx: Vista, Server 2003, XP SP1, XP, 2000, ME, NT 4, 98, 95 OSR2 ConnectNamedPipe: Vista, Server 2003, XP SP1, XP, 2000, NT 4, NT 3 Beep: Vista, Server 2003, XP SP1, XP, 2000, ME, 98, 95 OSR2, 95
编写函数来确定真实的OS版本很简单; 从最新的操作系统到最旧的操作系统,并使用GetProcAddress检查导出的API.用任何语言实现这一点应该是微不足道的.
Delphi中的以下代码是从免费的DSiWin32库中提取的:
TDSiWindowsVersion = (wvUnknown, wvWin31, wvWin95, wvWin95OSR2, wvWin98,
wvWin98SE, wvWinME, wvWin9x, wvWinNT3, wvWinNT4, wvWin2000, wvWinXP,
wvWinNT, wvWinServer2003, wvWinVista);
function DSiGetWindowsVersion: TDSiWindowsVersion;
var
versionInfo: TOSVersionInfo;
begin
versionInfo.dwOSVersionInfoSize := SizeOf(versionInfo);
GetVersionEx(versionInfo);
Result := wvUnknown;
case versionInfo.dwPlatformID of
VER_PLATFORM_WIN32s: Result := wvWin31;
VER_PLATFORM_WIN32_WINDOWS:
case versionInfo.dwMinorVersion of
0:
if Trim(versionInfo.szCSDVersion[1]) = 'B' then
Result := wvWin95OSR2
else
Result := wvWin95;
10:
if Trim(versionInfo.szCSDVersion[1]) = 'A' then
Result := wvWin98SE
else
Result := wvWin98;
90:
if (versionInfo.dwBuildNumber = 73010104) then
Result := wvWinME;
else
Result := wvWin9x;
end; //case versionInfo.dwMinorVersion
VER_PLATFORM_WIN32_NT:
case versionInfo.dwMajorVersion of
3: Result := wvWinNT3;
4: Result := wvWinNT4;
5:
case versionInfo.dwMinorVersion of
0: Result := wvWin2000;
1: Result := wvWinXP;
2: Result := wvWinServer2003;
else Result := wvWinNT
end; //case versionInfo.dwMinorVersion
6: Result := wvWinVista;
end; //case versionInfo.dwMajorVersion
end; //versionInfo.dwPlatformID
end; { DSiGetWindowsVersion }
function DSiGetTrueWindowsVersion: TDSiWindowsVersion;
function ExportsAPI(module: HMODULE; const apiName: string): boolean;
begin
Result := GetProcAddress(module, PChar(apiName)) <> nil;
end; { ExportsAPI }
var
hKernel32: HMODULE;
begin { DSiGetTrueWindowsVersion }
hKernel32 := GetModuleHandle('kernel32');
Win32Check(hKernel32 <> 0);
if ExportsAPI(hKernel32, 'GetLocaleInfoEx') then
Result := wvWinVista
else if ExportsAPI(hKernel32, 'GetLargePageMinimum') then
Result := wvWinServer2003
else if ExportsAPI(hKernel32, 'GetNativeSystemInfo') then
Result := wvWinXP
else if ExportsAPI(hKernel32, 'ReplaceFile') then
Result := wvWin2000
else if ExportsAPI(hKernel32, 'OpenThread') then
Result := wvWinME
else if ExportsAPI(hKernel32, 'GetThreadPriorityBoost') then
Result := wvWinNT4
else if ExportsAPI(hKernel32, 'IsDebuggerPresent') then //is also in NT4!
Result := wvWin98
else if ExportsAPI(hKernel32, 'GetDiskFreeSpaceEx') then //is also in NT4!
Result := wvWin95OSR2
else if ExportsAPI(hKernel32, 'ConnectNamedPipe') then
Result := wvWinNT3
else if ExportsAPI(hKernel32, 'Beep') then
Result := wvWin95
else // we have no idea
Result := DSiGetWindowsVersion;
end; { DSiGetTrueWindowsVersion }
---更新2009-10-09
事实证明,在Vista SP1及更高版本上进行"未记录的"操作系统检测变得非常困难.查看API更改显示所有Windows 2008功能也在Vista SP1中实现,并且所有Windows 7功能也在Windows 2008 R2中实现.太糟糕了 :(
---更新结束
FWIW,这是我在实践中遇到的一个问题.我们(我工作的公司)有一个程序,当Vista发布时(以及之后几周......),它还没有真正适用于Vista.它也不在兼容层下工作.(一些DirectX问题.不要问.)
我们不想让自己太聪明的用户在Vista上运行这个应用程序 - 兼容模式与否 - 所以我必须找到一个解决方案(一个比我聪明的人指向正确的方向;上面的东西不是我的想法).现在我发布它是为了你的乐趣,并帮助所有将来必须解决这个问题的可怜的灵魂.谷歌,请索引这篇文章!
如果您有更好的解决方案(或我的升级和/或修复),请在此处发布答案...

WMI QUery:
"Select * from Win32_OperatingSystem"
编辑:其实更好的是:
"Select Version from Win32_OperatingSystem"
您可以在Delphi中实现这一点,如下所示:
function OperatingSystemDisplayName: string;
function GetWMIObject(const objectName: string): IDispatch;
var
chEaten: Integer;
BindCtx: IBindCtx;
Moniker: IMoniker;
begin
OleCheck(CreateBindCtx(0, bindCtx));
OleCheck(MkParseDisplayName(BindCtx, PChar(objectName), chEaten, Moniker));
OleCheck(Moniker.BindToObject(BindCtx, nil, IDispatch, Result));
end;
function VarToString(const Value: OleVariant): string;
begin
if VarIsStr(Value) then begin
Result := Trim(Value);
end else begin
Result := '';
end;
end;
function FullVersionString(const Item: OleVariant): string;
var
Caption, ServicePack, Version, Architecture: string;
begin
Caption := VarToString(Item.Caption);
ServicePack := VarToString(Item.CSDVersion);
Version := VarToString(Item.Version);
Architecture := ArchitectureDisplayName(SystemArchitecture);
Result := Caption;
if ServicePack <> '' then begin
Result := Result + ' ' + ServicePack;
end;
Result := Result + ', version ' + Version + ', ' + Architecture;
end;
var
objWMIService: OleVariant;
colItems: OleVariant;
Item: OleVariant;
oEnum: IEnumvariant;
iValue: LongWord;
begin
Try
objWMIService := GetWMIObject('winmgmts:\\localhost\root\cimv2');
colItems := objWMIService.ExecQuery('SELECT Caption, CSDVersion, Version FROM Win32_OperatingSystem', 'WQL', 0);
oEnum := IUnknown(colItems._NewEnum) as IEnumVariant;
if oEnum.Next(1, Item, iValue)=0 then begin
Result := FullVersionString(Item);
exit;
end;
Except
// yes, I know this is nasty, but come what may I want to use the fallback code below should the WMI code fail
End;
(* Fallback, relies on the deprecated function GetVersionEx, reports erroneous values
when manifest does not contain supportedOS matching the executing system *)
Result := TOSVersion.ToString;
end;

如何获取系统文件的版本？
最好的文件是kernel32.dll,位于%WINDIR%\ System32\kernel32.dll中.
有API来获取文件版本.例如:我正在使用Windows XP - >"5.1.2600.5512(xpsp.080413-2111)"
另一种方案:
阅读以下注册表项:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName
或来自的其他钥匙
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion
以下内容适用于 Windows 10，但应用程序清单中没有列出 Windows 10 GUID：
uses
System.SysUtils, Winapi.Windows;
type
NET_API_STATUS = DWORD;
_SERVER_INFO_101 = record
sv101_platform_id: DWORD;
sv101_name: LPWSTR;
sv101_version_major: DWORD;
sv101_version_minor: DWORD;
sv101_type: DWORD;
sv101_comment: LPWSTR;
end;
SERVER_INFO_101 = _SERVER_INFO_101;
PSERVER_INFO_101 = ^SERVER_INFO_101;
LPSERVER_INFO_101 = PSERVER_INFO_101;
const
MAJOR_VERSION_MASK = $0F;
function NetServerGetInfo(servername: LPWSTR; level: DWORD; var bufptr): NET_API_STATUS; stdcall; external 'Netapi32.dll';
function NetApiBufferFree(Buffer: LPVOID): NET_API_STATUS; stdcall; external 'Netapi32.dll';
type
pfnRtlGetVersion = function(var RTL_OSVERSIONINFOEXW): LONG; stdcall;
var
Buffer: PSERVER_INFO_101;
ver: RTL_OSVERSIONINFOEXW;
RtlGetVersion: pfnRtlGetVersion;
begin
Buffer := nil;
// Win32MajorVersion and Win32MinorVersion are populated from GetVersionEx()...
ShowMessage(Format('GetVersionEx: %d.%d', [Win32MajorVersion, Win32MinorVersion])); // shows 6.2, as expected per GetVersionEx() documentation
@RtlGetVersion := GetProcAddress(GetModuleHandle('ntdll.dll'), 'RtlGetVersion');
if Assigned(RtlGetVersion) then
begin
ZeroMemory(@ver, SizeOf(ver));
ver.dwOSVersionInfoSize := SizeOf(ver);
if RtlGetVersion(ver) = 0 then
ShowMessage(Format('RtlGetVersion: %d.%d', [ver.dwMajorVersion, ver.dwMinorVersion])); // shows 10.0
end;
if NetServerGetInfo(nil, 101, Buffer) = NO_ERROR then
try
ShowMessage(Format('NetServerGetInfo: %d.%d', [Buffer.sv101_version_major and MAJOR_VERSION_MASK, Buffer.sv101_version_minor])); // shows 10.0
finally
NetApiBufferFree(Buffer);
end;
end.
更新：NetWkstaGetInfo()可能也可以工作，类似于“NetServerGetInfo()”，但我还没有尝试过。
