Black Screen For About 15-20 Seconds Then Lockscreen Appears?

I've been running the official Enterprise build of 8 for a few days now, but it seems some things are glitching on me that didn't in the RP and a glitch is occurring that has been occurring since the CP.

For starters, in metro IE 10, there's sometimes a text lag where I type but it isn't instantly shown. It happens on a random odd occasion. That didn't happen with the RP but did with the CP.

Another odd one is with Recycle Bin. If there are several items in it and I delete them, the progress bar appears and shows the operation is complete (in the address bar). But there are still like five things left in it, but refreshing the view shows everything is gone, seems likes a render issue that has been prevalent for me since I think the DP.

Also, there's an awkward amount of time from the boot screen to the lock/logon screen that normally and socially accepted. There's just a black screen for about 15-20 seconds then the lock screen appears.

I've found a bug in Task Manger in the Startup tab. I know for a fact that there has to be AT LEAST five startup items, but in the Startup tab, it doesn't report any startup items.

Other than that, everything is working fine. But it seems boot time isn't as fast as usual, maybe due to the startup items issue, but it's all solid.
