Open a slow or folder-unresponsive solution with video folders

Failure Resolution: This behavior can often occur for 2 reasons:

A. The system appears after some anti-virus software has been installed. Part of the anti-virus software real-time monitoring functions, when the presence of large volumes of compressed packets or ISO files of the directory, will automatically extract these files for scanning, for some poor configuration of the host, will lead to slow speed. It is recommended to set antivirus software on your own and turn off this feature.

B. There are no anti-virus software installed. XP has a feature that automatically extracts multimedia file information and makes it a preview. , XP will automatically scan and read information about these files and display the first screen of their thumbnails or videos. If you have a large number of folders or a large volume or high compression rate of video files (especially dvdrip,rmvb), this process to invoke the decompression program, for the configuration of the lower host, easy to make the system running very much lower, serious will also cause the crash

Workaround: The preview file for the video file in Windows 2000/xp "Shmedia.dll" plays a decisive role in canceling the video preview of the system: Click start → run to enter "Regsvr32/u Shmedia.dll" in the Open Run dialog box command, "OK" will pop up a successful dialog box, then "OK". In the future, if you want to turn on the video preview feature again, just enter the "regsvr32 shmedia.dll" command in the "Run" dialog box again.
