Question

我正在尝试使用Delphi从Windows注册表获取BIOS版本。我的问题是所有Windows版本的子项路径都不相同。

Windows 10：Reg.OpenKey('\HARDWARE\DESCRIPTION\SYSTEM\BIOS',False)

Windows 7：Reg.OpenKey('\HARDWARE\DESCRIPTION\SYSTEM',False)

有没有办法找到BIOS版本，无论它实际上是什么路径？

从Windows Vista开始，您可以使用Win32_BIOS WMI类来获取BIOS版本。试试这个示例代码。

{$APPTYPE CONSOLE}

{$R *.res}

uses
  System.SysUtils,
  Winapi.ActiveX,
  System.Win.ComObj,
  System.Variants;



procedure  GetWin32_BIOSInfo;
const
  WbemUser            ='';
  WbemPassword        ='';
  WbemComputer        ='localhost';
  wbemFlagForwardOnly = $00000020;
var
  FSWbemLocator : OLEVariant;
  FWMIService   : OLEVariant;
  FWbemObjectSet: OLEVariant;
  FWbemObject   : OLEVariant;
  oEnum         : IEnumvariant;
  iValue        : LongWord;
begin;
  FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
  FWMIService   := FSWbemLocator.ConnectServer(WbemComputer, 'root\CIMV2', WbemUser, WbemPassword);
  FWbemObjectSet:= FWMIService.ExecQuery('SELECT * FROM Win32_BIOS','WQL',wbemFlagForwardOnly);
  oEnum         := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant;
  while oEnum.Next(1, FWbemObject, iValue) = 0 do
  begin
    Writeln(Format('SerialNumber         %s',[String(FWbemObject.SerialNumber)]));
    Writeln(Format('SMBIOSBIOSVersion    %s',[String(FWbemObject.SMBIOSBIOSVersion)]));
    Writeln(Format('Version              %s',[String(FWbemObject.Version)]));

    Writeln('');
    FWbemObject:=Unassigned;
  end;
end;


begin
 try
    CoInitialize(nil);
    try
      GetWin32_BIOSInfo;
    finally
      CoUninitialize;
    end;
 except
    on E:EOleException do
        Writeln(Format('EOleException %s %x', [E.Message,E.ErrorCode]));
    on E:Exception do
        Writeln(E.Classname, ':', E.Message);
 end;
 Writeln('Press Enter to exit');
 Readln;
end.
