just a quick question, when u deselected the sounds in windowblinds, did you then apply changes again?., i know it may sound like a silly question but it is easy to overlook. hope your able to work it out

Display Properties > Windowblinds Button > Settings Tab > UNcheck "Play Sounds defined by the skin (if any)" > Apply Changes Button

If the above doesn't work then go to the control panel. sounds and audio devices, click on the sounds tap and make the changes there.   

Go to your control panel and click the sounds and audio devices icon. There go to sounds tab. Look through the listed sounds and make your changes or choose another sounds scheme; such as the windows default. Say apply and ok...
Hope this solves the problem.

If the above doesn't work, just delete all sound files from ur wbskinfolder.

Sacrificing a frog(boy) {or to a frog(boy)}might help too 

The option to not use sounds dosnt work in WB  

Bilbo is correct...delete the .wav files from the skins folder.

Can you give me an example of a skin that has it's own sounds, cause I haven't heard a thing since early version 4. I've got mine unchecked and have for a long time. I want to test it and see.

I wonder if having it unchecked during upgrades has had anything to do with it.......

Folks, am I missing something here, just use the built in Windows Volume Control and press mute. Way to easy, I have to be missing something here.   

That mutes everything . . the OP jusst wants to mute the skin sounds.

Neutronium DM has button sounds   

Thanks for all your help.
The sounds don't show up in the windows control panel/sounds ect... havr tried setting that to "None".
Yes I applied changes after changing settings in windowblinds, still didn't work.
Followed Bilbo's advise, eventually found the files in C:\Documents and Settings\All Users\Documents\Stardock\WindowBlinds\Benchwarmer Ultimate. Had to change to a diferent skin before I could delete the "Delete to bin" file as it would be in use while I was trying to delete it!!!
But its all done now so THANK YOU ALL VERY MUCH for your help.
