Hi everyone

My computer allowed some windows updates to be installed today and I have since noticed that I have no volume icon, battery or network icons in my notification area on my toolbar. I have tried to get this back via the taskbar and start menu properties but under the systems icons sections only the clock is selectable. The volume, network and power boxes won't let me tick them? Is this likely to be linked to the updates?

Please help as it's driving me mad not having a shortcut to controlling the volume and not being able to check my internet connection or battery status.

Thanks
