Alan has a Windows 7 64 bit home built computer, and has an M-Audio Delta 1010 audio card. Every time he shuts down Windows, he has to hold down the power button to shut it off. He's figured out there are two services preventing it from shutting down: audiosrv and audioendpointbuilder.
First, he should check M-Audio's support site to see if they have any fix. He has checked into gpedit.msc, a Microsoft plugin that will allow him to configure the computer more. He plans to use that to insert a batch file that will shut down those services upon shut down. Leo thinks that's a good idea and should solve his problem.
