I run SP2 with all the updates. I run Spybot S&D and Avast! Antivirus frequently. I recently upgraded SECRETMAKER (a SPAM/pop-up blocker), which I have been using without problems. My Taskbar, Start button, and Desktop icons disappeared immediately. Right-clicking the screen does nothing. Re-booting brings me back to the wallpaper I use for my desktop. Ctrl+Esc does nothing. Re-booting in Safe Mode does nothing. ScanDisk (from a command prompt) no longer functions. I HAVE RE-INSTALLED MY OS BUT I STILL HAVE THE SAME PROBLEM.
My Task Manager still works. Is there anything I can do with it? Can I somehow get into System Restore (and restore my previous settings)?
