To free up about 23 MBytes of memory, you can remove the Realtek HD Audio Manager from your task bar. This application is a fairly elaborate utility for working with audio. Its icon is attached.
To remove it, find the Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run\RTHDCPL. Note its value. Then delete the registry key, shutdown and restart.
To put it back in the taskbar temporarily, run the program that was named by the registry key you deleted. Typically it's C:\Program Files\Realtek\Audio\Drivers\WDM\RTHDCPL.exe. To put it back permanently, create an alias and put it into the Start menu under Start > All Programs > Startup.
