请英语好的朋友帮助修改一下这句话,用于it方面的presentation,尽量口语化,并且简单易懂.
在座的有谁在电脑上安装了itunes,可你们时候知道在itunes安装完成后,会在电脑开机的时候默认启动“iTunesHelper”和“QuickTime Task”这两个程序.
（用于presentation,请将词句翻译的尽量口语化.
Is there anyone install 'itunes' in your computer,do you know after
your install the 'itunes' completely,there are two services which named
'ituneshelper' and quicktime task' will be automatically set to your startup.
