run on startup - snap in Group Policy

Dave is right in one regard. You should configure programs
after you install them to "not" start at windows startup.
On the other hand you certainly can use msconfig along
with the regedit to clear programs from the startup.
gostart\run and type in msconfig then click ok. Now click
the startup tab and uncheck any program you don't want
starting when windows starts. Then gorunregedit and
click the + signs beside the entries in this order.
HKEY_LOCAL_MACHINE\Software\Microsoft\SharedTools\ StartupFo
lder and StartupReg. Click StartupFolder first and right
click on any program you don't want in the Startup folder
and click delete and do the same for StartupReg. Be
careful in the registry. When in doubt export the key to a
folder of your choice and then you can double click to
reinstall it if you made an error. The registry is the
heart of your OS so editing it should be done with
caution. On the other hand it isn't the big dark secret
that most MVPs make it out to be. Good luck.
