Thanks to anyone willing to help me. I own an emachines cpu with windows home edition. After I log on to my CPU it goes to my background but the desktop doesn't show up. I open the Task Manager and manually start explorer.exe and the desktop opens. But afterwards no exe files I download will open, no options in my control panel will open, internet explorer (using Firefox now)won't open, and several other things won't open( saving links with right click(in Firefox), hearts game, cmd.exe opens but closes instantly after, can't use the "open with" command). Everything else seems to be working O.K.. I noticed in the task Manager that certain tasks that start with the desktop didn't start( two I know are alg.exe, and wscntfy.exe). Any help will really be appreciated. Ask for anymore info if you need to, i am more than willing to give it.
