前面介绍怎么样调用动态连接库里的InstallReactOS函数，下面就来分析这个函数的代码，看看这个函数是怎么运行向导界面，又做了些什么样的工作。如下：
#001 DWORD WINAPI
#002 InstallReactOS(HINSTANCE hInstance)
#003 {
#004 TCHAR szBuffer[MAX_PATH];
#005 DWORD LastError;
#006 HANDLE token;
#007 TOKEN_PRIVILEGES privs;
#008
在ReactOS目录里创建安装的LOG文件。
#009 InitializeSetupActionLog(FALSE);
#010 LogItem(SYSSETUP_SEVERITY_INFORMATION,L"Installing ReactOS");
#011
初始化注册配置相关项。
#012 if (!InitializeProfiles())
#013 {
#014 DebugPrint("InitializeProfiles() Failed");
#015 return 0;
#016 }
#017
#018 if (!CreateShortcuts())
#019 {
#020 DebugPrint("InitializeProfiles() Failed");
#021 return 0;
#022 }
#023
创建安全相关的帐号管理。
#024 /* Initialize the Security Account Manager (SAM) */
#025 if (!SamInitializeSAM())
#026 {
#027 DebugPrint("SamInitializeSAM() Failed!");
#028 return 0;
#029 }
#030
#031 /* Create the semi-random Domain-SID */
#032 if (!CreateRandomSid(&DomainSid))
#033 {
#034 DebugPrint("Domain-SID creation Failed!");
#035 return 0;
#036 }
#037
#038 /* Set the Domain SID (aka Computer SID) */
#039 if (!SamSetDomainSid(DomainSid))
#040 {
#041 DebugPrint("SamSetDomainSid() Failed!");
#042 RtlFreeSid(DomainSid);
#043 return 0;
#044 }
#045
#046 /* Append the Admin-RID */
#047 AppendRidToSid(&AdminSid,DomainSid,DOMAIN_USER_RID_ADMIN);
#048
创建管理员帐号。
#049 /* Create the Administrator account */
#050 if (!SamCreateUser(L"Administrator",L"",AdminSid))
#051 {
#052 /* Check what the error was.
#053 * If the Admin Account already exists,then it means Setup
#054 * wasn't allowed to finish properly. Instead of rebooting
#055 * and not completing it,let it restart instead
#056 */
#057 LastError = GetLastError();
#058 if (LastError != ERROR_USER_EXISTS)
#059 {
#060 DebugPrint("SamCreateUser() Failed!");
#061 RtlFreeSid(AdminSid);
#062 RtlFreeSid(DomainSid);
#063 return 0;
#064 }
#065 }
#066
#067 RtlFreeSid(AdminSid);
#068 RtlFreeSid(DomainSid);
#069
#070 /* ROS HACK,as long as NtUnloadKey is not implemented */
#071 {
#072 NTSTATUS Status = NtUnloadKey(NULL);
#073 if (Status == STATUS_NOT_IMPLEMENTED)
#074 {
#075 /* Create the Administrator profile */
#076 PROFILEINFOW ProfileInfo;
#077 HANDLE hToken;
#078 BOOL ret;
#079 #define logoN32_logoN_NETWORK 3
#080 ret = logonUserW(L"Administrator",logoN32_logoN_NETWORK,logoN32_PROVIDER_DEFAULT,&hToken);
#081 if (!ret)
#082 {
#083 DebugPrint("logonUserW() Failed!");
#084 return 0;
#085 }
#086 ZeroMemory(&ProfileInfo,sizeof(PROFILEINFOW));
#087 ProfileInfo.dwSize = sizeof(PROFILEINFOW);
#088 ProfileInfo.lpUserName = L"Administrator";
#089 ProfileInfo.dwFlags = PI_NOUI;
#090 LoadUserProfileW(hToken,&ProfileInfo);
#091 CloseHandle(hToken);
#092 }
#093 else
#094 {
#095 DPRINT1("ROS HACK not needed anymore. Please remove it/n");
#096 }
#097 }
#098 /* END OF ROS HACK */
#099
创建系统工作的临时目录。
#100 CreateTempDir(L"TEMP");
#101 CreateTempDir(L"TMP");
#102
创建system目录。
#103 if (GetWindowsDirectory(szBuffer,sizeof(szBuffer) / sizeof(TCHAR)))
#104 {
#105 PathAddBackslash(szBuffer);
#106 _tcscat(szBuffer,_T("system"));
#107 CreateDirectory(szBuffer,NULL);
#108 }
#109
根据syssetup.inf文件来安装相应的组件，还安装PNP管理器。
#110 if (!CommonInstall())
#111 return 0;
#112
初始化让用户选择输入参数的向导界面。
#113 InstallWizard();
#114
#115 SetupCloseInfFile(hSysSetupInf);
设置系统安装的类型。
#116 SetSetupType(0);
#117
#118 LogItem(SYSSETUP_SEVERITY_INFORMATION,L"Installing ReactOS done");
#119 TerminateSetupActionLog();
#120
#121 /* Get shutdown privilege */
#122 if (! OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&token))
#123 {
#124 DebugPrint("OpenProcessToken() Failed!");
#125 return 0;
#126 }
#127 if (!LookupPrivilegeValue(
#128 NULL,
#129 SE_SHUTDOWN_NAME,
#130 &privs.Privileges[0].Luid))
#131 {
#132 DebugPrint("LookupPrivilegeValue() Failed!");
#133 return 0;
#134 }
#135 privs.PrivilegeCount = 1;
#136 privs.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
#137 if (AdjustTokenPrivileges(
#138 token,
#139 FALSE,
#140 &privs,
#141 0,
#142 (PTOKEN_PRIVILEGES)NULL,
#143 NULL) == 0)
#144 {
#145 DebugPrint("AdjustTokenPrivileges() Failed!");
#146 return 0;
#147 }
#148
退系统，并重新启动。
#149 ExitWindowsEx(EWX_REBOOT,0);
#150 return 0;
#151}
