Why does Windows 10 take a long time to boot?

Windows 10 long boot time

Hello,

I've installed Windows 10 on release day and I've noticed that my boot time went from about less than 15 secs to more than a minute. There was a black screen before the welcome screen and it was just unusually long.

I have a lenovo laptop and I'm not sure what other details I should include here (not very tech-savvy). That's why I'm not very sure what happened and what I should do.

Thank you in advance for your help.

Re: Windows 10 long boot time

My boot time with W10 was a horrendous 6 minutes. I have a Z570 Lenovo. I've switched back to W7 for now. Boot time 10 seconds.

Sorry, I don't have an answer.

Re: Windows 10 long boot time

I had to do another defrag / optimize after upgrading to W10. It did help with boot time, still not as fast as windows 7 but better than what it was after the initial upgrade.
