Solved!!

been researching this since upgrading and updating and vista machine on the side … tried the services and startups, no good, tired xbootmgr from the toolkit, just a big gap after login and black screen reaching desktop … triend the disabeling rootkit boot, protection and delayed load for avast, still no good … from the link tried adding AlwaysConnectedWaitSeconds=360 to the INI file … Little better performance … Wait for it … Disable Streaming Updates under > Settings > Cloud Services …

Booted stright to desktop as expected without the black screen delay …

your all welcome, I only post because I didnt see the answer elsewhere … good luck
