为了建立被删除掉的ICS服务，浪费了3个小时

　　为了解决adhoc的Internet共享问题，太着急了结果看都没看运行了一行命令。
sc delete sharedaccess，结果自己爽歪歪的。Internet共享的服务就这样被删掉了，刚做好系统，不甘心重装。于是。。。尝试建立回去。
sc create sharedaccess binpath= "c:\windows\system32\svchost.exe -k netsvcs" type= share start= auto depend= netman/winmgmt DisplayName= "Windows Firewall/Internet Connection Sharing " tag= no error= normal

注意，等号后面有空格。跑完这个命令，服务建好了，但是不能用的。会提示系统找不到指定文件，必须再导入一个注册表

导入到注册表中，并重启机器.打开命令行窗口，输入 netsh firewall reset.

就这样郁闷的搞定了。
前前后后3小时，最郁闷的就是sc命令等号后必须要空格，脑残啊
