Yesterday I got a message in the solve PC issues icon tray that I could optimize performance by turning off startup programs.
I did turn some off but I cannot remember what exactly. Today my PC has started with errors. On the taskbar most of the icons have been replaced by Windows live mail icons and when I click on them only Windows live mail will open. If I find the exe file on the hard drive like WinWord and click on it I still get Windows Live mail opening instead. Even in control panel etc if I try and open system config I only get Windows live mail. Many other options don't work at all when I click on them or open windows live mail.
Don't know if my problem is a result of my editing the startup thing or not. I can't get to them now to check.
