Disable Windows 7 DLNA exposure
Posted by jpluimers on 2011/05/13
It looks like when you install Windows Media Player in Window 7, it will expose your media library for DLNA access by default for any user that chooses “quick” settings.
This even when you have not turned on media streaming, or not enabled the “Automatically allow devices to play my media” (this link has some screenshots on those settings).
I know few users who go the whole nine yards around those “quick” settings, so pretty much any Windows 7 user has their media library exposed as DLNA in your Home or Work networks (DLNA seems disabled on Public networks by default).
This is both a pollution of your DLNA space (for instance making it more difficult from your digital TV to to select the correct DLNA source), and an exposure. Any malware in your network might so some discovery (and yes, truckloads of PC’s in Work or Home networks have such malware running).
Though searching for “Winodws 7” “Disable DLNA” returns few good results, the actual trick is easy:
- On the start menu, type “Manage advanced sharing settings”
- Click the arrow next to “Home or work”
- Under “Media Streaming”, click “Choose media streaming options”
- Click on the “Block all” button
- Click the “OK” button
- Close the “Advanced sharing settings” window
