The "provided by..." is just a leftover from the installation from your previous ISP. Nothing to get worried about...actually, you can just disregard it and move on to your slow boot problem.
If your computer is slow to boot, you might want to take a look at running a Disk Cleanup, first. Just use the default settings. Run that first. Once you're done, run a disk defrag as well. See if there is any improvement and post your results here please?
