If you have a shared mapped network drive with users constantly changing files, users windows explorer may flicker as it constantly updates that window with the changes to files.

This can be an annoying for users and cause un-neccessary network traffic.
The behaviour can be controlled with the following registry keys :

Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoRemoteRecursiveEvents = 1 Turn off for tier 2 paths below the root
NoRemoteChangeNotify = 1 Turn off from top level

The key can be set and HKCU and HKLM level depending if you want to impact all or certain users.
