My work laptop is becoming almost unbearable lately. After logon the wallpaper appears immediately but the Taskbar and Desktop icons take fully three minutes before they even appear! Add another two or more minutes for the disk activity to slow down and it can take me at least five minutes after logon to be able to open any application. During this time the disk activity LED is essentially solid on, so something is happening in the background. After everything stops the laptop acts normally and is not slow during use. There is one application, FreeCommander, that once launched takes minutes before it appears. The Task Manager shows the process running and subsequent relaunches just show more of the same process. None of these symptoms appeared until recently and I cannot pinpoint any significant change that may have occurred. I have tried reinstalling FreeCommander but the problem stays. Reinstalling Adobe Acrobat did cure its identical symptom to FreeCommander. Tech support suggests replacing the NTUSER.DAT file with the generic one that comes with a clean installation. Any thoughts on that approach or do you have a different suggestion?
