去软微官网找资料，发现该日志相关信息如下：

 

Your event log may contain events that are similar the following:

Notification Thread Hidden Window {417F6FAB-6A56-49C6-B9A9-6A795A0C73C1}"

原因：

These events may be logged when both of the following conditions are true: 
     
     
     
     

      
      
      
      
A high volume of disk I/O operations are performed. 
      
      
      
      
A time-out occurs during the interaction between Logical Disk Manager (LDM) and Plug and Play (PNP). 
     
     
     
     
These messages are .ly informational and can be safely ignored

看来服务器磁盘的SATA盘的I/O，将可能会成为服务器性能的瓶颈。
