请问:怎样才能获得一个正在运行的进程的句柄呐?

如果是当然进程，GetCurrentProcess(),如果是其它，需要找到其它进程的ID然后使用OpenPrcess,记住，你的进程需要相应的权限。

BOOL EnableDebugPrivilege(BOOL fEnable/* =TRUE */)
{
BOOL fOK = FALSE;
HANDLE hToken = NULL;
if(OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&hToken)){
TOKEN_PRIVILEGES tp;
tp.PrivilegeCount =1;
LookupPrivilegeValue(NULL,SE_DEBUG_NAME,&tp.Privileges[0].Luid);
tp.Privileges[0].Attributes = fEnable ? SE_PRIVILEGE_ENABLED : 0;
AdjustTokenPrivileges(hToken,FALSE,&tp,sizeof(tp),NULL,NULL);
fOK = (GetLastError()==ERROR_SUCCESS);
CloseHandle(hToken);
}
return fOK;
}

该程序在硬盘上的存储路径是已知的.

应当知道执行程序的名字吧,GetModuleHandle(PCTSTR pszModule)可得到他的句柄

自己改吧，终止和启动Explorer
