Hi NSchwender. Just wondering possible program conflicts. Are you using for example Zemana Antilogger or other similar programs? When i was working with this issue, i didn't try to remove Zemana. I ended up to install another AV to my mom's laptop and it's working well, so i have not bothered to work with that issue since. But this possible conflict issue came to my mind and might help other with same problem. I also have Zemana antilogger and the latest avast, but with W7 there's no slow boot issue.
