Jim,
For startup you can use a program called Autorun:
http://www.microsoft.com/technet/sysinternals/utilities/autoruns.mspx
Click the LOGON tab
If there are things like Messengers (not MSN) then you can delete them
Also delete Real Media Updater, Adobe Speedlauncher, Quicktime Task,
Microsoft Office OSA.exe etc, but do not delete anything like your virus
software or firewall because you'll be unprotected if you do. Maybe it would
be better to untick those entries, restart the computer & then if all is ok
then use the autorun application to delete those entries
You can also look in your startup folder (START | All Programs | Startup).
If there is something in there that needs deleting then right-click the
START button | Explore or Open then navigate to the startup folder & delete
the links there.
If you have MSN running on startup then you will need to open MSN/Live
Messenger | Tools | Options (General or Preferences tab) & remove the tick
from Automatically run this application when I log onto Windows. Click
APPLY, click OK & then right-click the system tray icon to exit the
application
You have to do MSN the above way as when it exits it replaces the link for
startup.
Hope this also helps,
