go to:
start, run, 'msconfig'
If you click on the startup tab it will list all the programs that windows starts on start-up. Look for something like sync manage or anything similar. uncheck the box and then re-start. Hopefully it will be gone.
You can google almost any of the programs starting up and it will tell you what it is. I check msconfig at least once a week to ensure nothing is there. A lot of programs put their auto-updater in there. I'd rather do it manually than have something running in the background taking up resources trying to update.

Good luck.
