Solve 1:

procedure CreateStartmenuLink(ExeFile, WorkPath, Args, Descr: string);
var
  MyObject: IUnknown;
  MyLink: IShellLink;
  MyFile: IPersistFile;
  ds: WideString;
  StartMenuDir: string;
  reg_info: TRegIniFile;
  reg: TRegistry;
  s: string;
begin
  reg_Info :=
    TRegIniFile.Create('Software\Microsoft\Windows\CurrentVersion\Explorer');
  StartMenuDir := reg_Info.ReadString('Shell Folders', 'Start Menu', '');
  reg_Info.Free;
  s := ExtractFilePath(StartMenuDir + '\' + Descr + '.lnk');
  ForceDirectories(s);
  if FileExists(StartMenuDir + '\' + Descr + '.lnk') then
    DeleteFile(StartMenuDir + '\' + Descr + '.lnk');
  MyObject := CreateComObject(CLSID_ShellLink);
  MyLink := MyObject as IShellLink;
  MyFile := MyObject as IPersistFile;
  MyLink.SetArguments(PChar(Args));
  MyLink.SetPath(PChar(ExeFile));
  MyLink.SetWorkingDirectory(PChar(WorkPath));
  s := ExtractFileName(StartMenuDir + '\' + Descr + '.lnk');
  s := copy(s, 1, length(s) - 4);
  MyLink.SetDescription(PChar(s));
  ds := StartMenuDir + '\' + Descr + '.lnk';
  MyFile.Save(PWChar(ds), false);
  reg := TRegistry.Create;
  reg.RootKey := HKEY_USERS;
  reg.openkey('.Default\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders', true);
  StartMenuDir := reg.ReadString('Start Menu');
  reg.closekey;
  reg.free;
  s := ExtractFilePath(StartMenuDir + '\' + Descr + '.lnk');
  ForceDirectories(s);
  if FileExists(StartMenuDir + '\' + Descr + '.lnk') then

{uses Windows, ShlObj, SysUtils, ...}

type
  TShellLinkInfo = record
    PathName: string;
    Arguments: string;
    Description: string;
    WorkingDirectory: string;
    IconLocation: string;
    IconIndex: integer;
    ShowCmd: integer;

  end;

function GetSpecialFolderPath(Folder: Integer; CanCreate: Boolean):

begin
  { Get path of selected location }
  SHGetSpecialFolderPath(0, FilePath, Folder, CanCreate);
  Result := FilePath;
end;

function CreateShellLink(const AppName, Desc: string; Dest: Integer): string;
{ Creates a shell link for application or document specified in  AppName with description Desc.
Link will be located in folder specified by Dest. Returns the full path name of the link file }
var
  SL: IShellLink;
  PF: IPersistFile;
  LnkName: WideString;
begin
  OleCheck(CoCreateInstance(CLSID_ShellLink, nil, CLSCTX_INPROC_SERVER, IShellLink,
    SL));
  { The IShellLink implementer must also support the IPersistFile interface.
  Get an interface pointer to it. }
  PF := SL as IPersistFile;
  OleCheck(SL.SetPath(PChar(AppName))); {set link path to proper file}
  if Desc <> '' then
    OleCheck(SL.SetDescription(PChar(Desc))); {set description}
  { create a path location and filename for link file }
  LnkName := GetSpecialFolderPath(Dest, True) + '\' + ChangeFileExt(AppName, '.lnk');
  PF.Save(PWideChar(LnkName), True); {save link file}
  Result := LnkName;
end;

Usage:

CreateShellLink('c:\programfiles\mycompany\myapp.exe', '', CSIDL_PROGRAMS);

Look up SHGetSpecialFolderLocation or "ShlObj.pas" for the CSIDL_constants.
