最开始，我停掉WINDOWS UPDATE，但没有解决，这个进程还是不时的偶尔冒出来，然后力图将CPU撑到100%，然后，网络性能，DISK I/O,都受影响。
原来，WINDOWS MODULE INSTALL也是用的这个EXE，果断停掉测试先。。
但，，但，，这也不是个事儿呀。。。。微软能把这些烂尾的弄好点么？？
To change Automatic Windows Update setting, go to Control Panel -> System and Maintenance -> Turn automatic updating on or off under Windows Update section. Under “Choose how Windows can install updates” section, click on radio button next to Never check for updates (not recommended) or Check for updates but let me choose whether to download and install them or Download updates but let me choose whether to install them. Then click on OK then click on Continue button for UAC prompt. Note that if you choose the not recommended option, you have to manually run the Windows Update to update your system.
