5 min delay on cold start between login screen and bg screen

Empty the prefetch folder and disable the AppXsvc from the registry.

Change the start key value from 3 to 4. The restart twice to be certain it has taken effect.

Then take another boot trace, to check the difference.

It worked! A split second signing in without black screen! Thanks so much zinou, you know what you are doing! Boot trace www.transfernow.net/17j8k8s1lt7d

Here boot trace with boot www.transfernow.net/71985261nedj

[EDIT] that previous record doesn't tell the truth, as I did it from new admin account which wasn't when this post was started. Sorry! I did new boot trace now from same account as where black screen was and it's here www.transfernow.net/89hix2p9qzfz

The boot trace shows a net improvement in the boot time; your desktop shows up a few seconds after you validate your credentials.But you should consider that this is a workaround and not definitive solution. AppXsvc disabled, you'll not be able to install applications from the Windows Store. If you don't mind, then let it as it is. Otherwise open another Thread to solve your Windows Store program.
