Specific reasons:
In the new WINDOWS8 operating system, Windows Task Manager is the name of Task Manager from Vista, Win7 era Taskmgr.exe renamed TM.exe, and this TM.exe and China Tencent QQ sister software TM Duplicate.
Tencent QQ and TM belong to a software core, the way to detect in the installation process is too simple to see if the process has the same name, this fault for Tencent such a large company is not supposed to happen, is caused by the carelessness of developers, even with Windows from the API to judge is much better than this. Believe that the late version of QQ will definitely improve the problem, after all, you can not expect someone else in Microsoft Windows TM.exe to rename. In fact, do not have to rename, is to judge the mechanism of QQ to strengthen.
Solution: When installing QQ or TM in Win8, turn task Manager off first.
