There are many threads here about slow boot in Windows 10, and at least one very long one. This was a problem reported more often last year. I would suggest you read through some of that and see if there's anything that helps.
E.g.
Solved Slow boot on Win10 compared to Win7 - Page 3 - Windows 10 Forums
Solved Very slow startup after Windows Anniversary update - Windows 10 Forums
Solved Windows 10 10586.3 and slow login problem - Windows 10 Forums
- there are plenty more.
Otherwise I can only suggest technical analysis using MS's tools as per my previous post.
