Problem: When end users were selecting the Start> Windows Security or Start > Arrow > Lock option in the desktop menus there is a 10 – 20 second delay before the menu appears. It also affected volume control speed and even the ability to select the Speaker icon on the task bar.
Solution: Microphone redirection. Disable anything to do with microphone redirection and then the menus listed above should then appear instantly.
