You can manually remove these entries, however it is advisable to create a backup "checkpoint" first. Search M$'s site for "create checkpoint" and look for an instruction page.
Remove the entries by right clicking on each one. Each time a warning message will come up and you have to click "Yes", then after removing the entries another message will ask if you want to "Restart Now". You can remove all of the entries before you restart, so you only have one restart.
