It seems like I am always having trouble with one computer or another. This time it's the family computer, not my fault.
My brother was trying to uninstall Windows Messenger because everytime the computer started it logged him in. Instead of just changing the Messenger settings or asking for help he want into Add or Remove programs > Add/Remove Windows components and checked everything other than Messenger.
Messenger has since disappeared but little things have stuffed up now. There is no longer anything in the Games folder, Entertainment folder, the volume control in the taskbar has been removed and when you open IE it says 'IE is running without add-ons'.
I think I have fixed the add-ons problem. I just deleted and made next shortcuts, that seemed to work. I tried to check 'Place volume icon in the task bar' in the sound settings but the error message 'Windows cannot display the volume control on the taskbar because the Volume Control program has not been installed. To install it use the Add/remove programs in Control Panel'.
I'm rather stuck with what to do.
