如何提高当前进程的权限

很多时候我们需要提高本进程的权限，比如要把DLL注入类似Winlogo、csrss系统进程。如果使用默认的权
限肯定是做不到的。

BOOL EnablePrivilege(LPCTSTR lpszPrivilegeName,BOOL bEnable)
{
    HANDLE hToken;
    TOKEN_PRIVILEGES tp;
    LUID luid;

    if(!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES |
        TOKEN_QUERY | TOKEN_READ,&hToken))
        return FALSE;
    if(!LookupPrivilegeValue(NULL, lpszPrivilegeName, &luid))
        return TRUE;

    tp.PrivilegeCount = 1;
    tp.Privileges[0].Luid = luid;
    tp.Privileges[0].Attributes = (bEnable) ? SE_PRIVILEGE_ENABLED : 0;

    AdjustTokenPrivileges(hToken,FALSE,&tp,NULL,NULL,NULL);

    CloseHandle(hToken);

    return (GetLastError() == ERROR_SUCCESS);

}

EnablePrivilege就可以使调用进程提高或取消某个权限， lpszPrivilegeName是要操作的权限，可以传入的值有（winnt.h定义）：

#define SE_CREATE_TOKEN_NAME              TEXT("SeCreateTokenPrivilege")
#define SE_ASSIGNPRIMARYTOKEN_NAME        TEXT("SeAssignPrimaryTokenPrivilege")
#define SE_LOCK_MEMORY_NAME               TEXT("SeLockMemoryPrivilege")
#define SE_INCREASE_QUOTA_NAME            TEXT("SeIncreaseQuotaPrivilege")
#define SE_UNSOLICITED_INPUT_NAME         TEXT("SeUnsolicitedInputPrivilege")
#define SE_MACHINE_ACCOUNT_NAME           TEXT("SeMachineAccountPrivilege")
#define SE_TCB_NAME                       TEXT("SeTcbPrivilege")
#define SE_SECURITY_NAME                  TEXT("SeSecurityPrivilege")
#define SE_TAKE_OWNERSHIP_NAME            TEXT("SeTakeOwnershipPrivilege")
#define SE_LOAD_DRIVER_NAME               TEXT("SeLoadDriverPrivilege")
#define SE_SYSTEM_PROFILE_NAME            TEXT("SeSystemProfilePrivilege")
#define SE_SYSTEMTIME_NAME                TEXT("SeSystemtimePrivilege")
#define SE_PROF_SINGLE_PROCESS_NAME       TEXT("SeProfileSingleProcessPrivilege")
#define SE_INC_BASE_PRIORITY_NAME         TEXT("SeIncreaseBasePriorityPrivilege")
#define SE_CREATE_PAGEFILE_NAME           TEXT("SeCreatePagefilePrivilege")
#define SE_CREATE_PERMANENT_NAME          TEXT("SeCreatePermanentPrivilege")
#define SE_BACKUP_NAME                    TEXT("SeBackupPrivilege")
#define SE_RESTORE_NAME                   TEXT("SeRestorePrivilege")
#define SE_SHUTDOWN_NAME                  TEXT("SeShutdownPrivilege")
#define SE_DEBUG_NAME                     TEXT("SeDebugPrivilege")
#define SE_AUDIT_NAME                     TEXT("SeAuditPrivilege")
#define SE_SYSTEM_ENVIRONMENT_NAME        TEXT("SeSystemEnvironmentPrivilege")
#define SE_CHANGE_NOTIFY_NAME             TEXT("SeChangeNotifyPrivilege")
#define SE_REMOTE_SHUTDOWN_NAME           TEXT("SeRemoteShutdownPrivilege")
#define SE_UNDOCK_NAME                    TEXT("SeUndockPrivilege")
#define SE_SYNC_AGENT_NAME                TEXT("SeSyncAgentPrivilege")
#define SE_ENABLE_DELEGATION_NAME         TEXT("SeEnableDelegationPrivilege")
#define SE_MANAGE_VOLUME_NAME             TEXT("SeManageVolumePrivilege")

参数bEnable=TRUE表示要提高第一个参数指定的权限。
