Just upgraded to Creative Cloud 4.7.0.400, from 24.09.2018 on Windows 8.

Weirdly my E-Mail client suddenly opens .doc-files in Illustrator CC. I checked Windows 8's default program setting for file extension .doc ... it's still set to "Word". The E-Mail client (Opera Mail) is pretty slim and itself has no way of setting file extension behaviours - it's depending on the systems settings.

The Bridge's file extension dialog in Bridge settings does not list .DOC files, so it's not set to illustrator there either.

However if i go into windows file extension settings again, highlight .doc and click "edit program" to take a closer look, THERE are TWO entries in "recommended program" to open .doc files with... Word and Illustrator CC. How come?

My e-mail client seems to take whatever first program is set as "recommended program" to open doc-files with.

This is bad, since i have no way of removing this setting in windows settings.
How come creative cloud thinks it would be a good choice to open .DOC files with?

Thanks and best regards,
Stephan
