所以你還是用菜鳥辦法吧

這兒是work 的. regedit 後,msmsgs 不會跟 windows 起來.俺不用OE.

真想擺老鳥樣的話:
run > gpedit.msc
navigate to admin templates > windows components > windows messenger in both computer config and user config. enable both "do not allow..." and "do not automatically.." in both locations.

tell ppl your os at the first place next time.
