Having updated the WMP files and such like, its still generating errors on startup. I can only assume now that the DRM component of my Windows installation is screwed and can’t be repaired. So, I’ve set the UPnP service to start after the spooler service, and we’ll see what happens now.

If this doesn’t work, I’ll try setting a batch file to run when my profile loads which will stop and restart the Zune and WMP services.

Edit: This hasn’t worked, so I’m going to add the following script to the startup folder (initally at least):

net stop WMPNetworkSvc
net stop ZuneNetworkSvc
net stop ZuneBusEnum
net stop upnphost

net start upnphost
net start WMPNetworkSvc
net start ZuneNetworkSvc
net start ZuneBusEnum
