1、Startup启动文件夹（windows 9x/XP/2000）
C:\Documents and Settings\All Users\「开始」菜单\程序\启动
2、注册表中RUN项添加自启动
[HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/RunOnce]
[HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Run]
[HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/RunOnceEx]
[HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/RunEX]
[HKEY_LOCAL_USER/Software/Microsoft/Windows/CurrentVersion/RunOnce]
[HKEY_LOCAL_USER/Software/Microsoft/Windows/CurrentVersion/Run]
[HKEY_LOCAL_USER/Software/Microsoft/Windows/CurrentVersion/RunOnceEX]
[HKEY_LOCAL_USER/Software/Microsoft/Windows/CurrentVersion/RunEX]
3、服务：计算机管理->服务列表->设为自动的服务会随系统启动
4、文件关联：例如exe文件，注册表项为"HKEY_CLASSES_ROOT/exefile/shell/open/command"%1"%\'
5、随系统启动的系统配置文件WIN.INI中的"RUN="和"LOAD="
6、随系统启动的系统配置文件SYSTEM.INI中的boot项中的"shell=explorer.exeC:\windows\filename"
7、计划任务，存放的定时作业可设置系统启动时任意时间调用程序。
