This was a problem that has been bugging me for a last few weeks. If anyone uses Skype for desktop you may of come across the Skype error below on Windows 8 shutdown.
This was bugging me for weeks and numerous posts on Skypes forum suggests this is resolved by a full re-installation. This did not work for me. There is a much simpler fix.
Turn off the “I sign out” sound on Skype.
After that has been changed no more error. Simple!
