Novell ZENworks Configuration Management 11.2.3a
Windows Explorer randomly crashes related to Nalshell.dll.
This is fixed in version 11.2.4 - see KB 7012027 "ZENworks Configuration Management 11.2.4 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7012027
This is quite close related to TID 7010695. Here specific code changes related to Windows 8 support in Nalshell.dll are causing the Windows Explorer crash.
