I have this problem, that my sister always lowers the volume on her account so the changes also affect me. Ad I have to then higher the volume on my account every single time. This has become really annoying. Is there away so I can stop this from happening? Like my sister can keep her volume how she wants and I can have a different volume. Or just preventing access to her volume control so she can't lower the volume. Please help? Thanks! Btw, I am running Windows XP Home SP2.
