但是cpu使用率都是99% , 本來以為是病毒, 但是抓不到!

經過爬文 , 決定用 Process Explorer 去看看這個rundll.exe 到底再跑啥

實在不知道原來w7 的系統裡有這個 game開頭的東東 ..
後來終於google 到某篇有關 rundll32.exe 跟 gameux.dll,GameUXShim 有關的文章 .
gameux.dll - rundll32.exe
間單講就是 微軟把W7 的 game explorer server 關掉了 , 但是W7 還是會連結到 server 去.. 所以 rundll32.exe 就一直在鬼打牆!
解決的辦法 :
去 : HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\GameUX\ServiceLocation
把 右邊的 Game 數值 改成 127.0.0.1 , 就可以了!

Copy 原文, 以免改天 連結也掛了 :
I just had a case of several of my old windows games refusing to start while the CPU would saturate doing nothing (Win 7).
After investigating a little, I found out that the cause for this was the Game Explorer (gameux) who meddled as soon as the game got started. It would try to connect to the Microsoft servers to collect infos. But it seems that the MS server (https://games.metaservices.microsoft.com/games/SGamesWebService.asmx) is dead now. So it loops indefinitely doing nothing, and all these game won't work anymore.
This bug affects all games listed in the windows registry at this location : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\GameUX. Others are unaffected.
This is totally silly, but can be easily solved. Some did it by deleting some dlls, but it is better to just change a registry key.
EvilEdDead explained it well here (thanks man !).
Just open Regedit, got to HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\GameUX\ServiceLocation and change the server address contained in the "Games" chain value to 127.0.0.1 or localhost (do a backup first if you wish).
This will solve the problem once and for all for all the games which had it.
----------
Alternative method : copy-paste the text below to a txt file and rename the extension as .reg instead of .txt, then double-click on the file to apply it.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\GameUX\ServiceLocation]
"Games"="127.0.0.1"
And to undo the changes, do the same with this instead :
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\GameUX\ServiceLocation]
"Games"="https://games.metaservices.microsoft.com/games/SGamesWebService.asmx"
