Windows 8.1 Explorer crashes when right-click –
this seems to bee a major problem in windows preview 8.1. explorer crashing on right click
To work around this until , Microsoft find a solution try the following
I have exactly the same issue with Windows 8.1 and right clicking on a object, and try to open or select properties, windows explorer crashed and restarted
After many hours, off disabling services one at a time after finding it worked when started with no services at all loaded, , I narrowed it down to an issue with the network components / context menu network links ,I removed any mapped drives and have to start my laptop with wireless off and no network cable,
Once Windows 8.1 has started I can right click no problem no dlnashext.dll errors and windows explorer restarting.
then connect network (activate wireless or plug cable) and everything works ok
So for me in Windows 8.1 only way I can avoid the dlnashext.dll errors on right click is to start the laptop with NO network connections then connect after log in and all is good works fine no errors.
Give that a go and see if it works for you
