How to force Windows 7 to update the DLNA shares?

Question

I am using my Windows 7 to share content via DLNA to my Google-TV. Frequently it doesn't update what it is sharing. At first I thought it was a codec problem, but then the media appeared a couple days later. The client has an update, and it sees deletions immediately, but still frequently doesn't find new files. Usually rebooting seems to work, but not always.

Answer 1

Luke's answer on a different question suggested that running Windows Media Player may cause the update to happen quicker. I don't usually run it, and running it this time resulted in everything updating. So this may in fact work.

Answer 2

Fast and usually working method to refresh the database is simply to restart Windows Media Player Network Sharing Service in batch file (.bat):

net stop WMPNetworkSvc

net start WMPNetworkSvc

pause

Answer 3

I made slightly updated batch for windows 7 (original was here: https://www.cnet.com/forums/discussions/windows-media-player-12-not-updating-library-370225/)

This is for 64-bit windows, if you have 32-bit change the "rem" prefix accordingly.

c:

net stop WMPNetworkSvc

cd %userprofile%\appdata\local\microsoft\media player

del *.wmdb

rem cd e:\program files\windows media player

net start WMPNetworkSvc

"%ProgramFiles(x86)%\Windows Media Player\wmplayer.exe" /prefetch:1

rem "%ProgramFiles%\Windows Media Player\wmplayer.exe" /prefetch:1

echo Done

pause

In my case it was not needed to run this batch every time when i try to stream videos to dlna devices, maybe once in two weeks or once in month.
