New Windows 10 Insider Preview Fast+Skip Build 18885 (20H1) - April 26 Insider

Used UUPDUMP.ml to DL and install, no issues.

Is anyone having problems connecting to a network Drive on this build? I have a USB drive connected to my router and when I try to connect to it my desktop Green Screens and reboots. The Green Screen flashes to fast to read it so I don't know the error code.

No, I used MR to backup to a network drive and I have accessed other resources on the network with no problems.

No 20HI button. 4 buttons, Slow, Fast, Release Preview and Skip. Fast was (and still is) preselected.
So for laughs I selected Skip, got this
Attachment 231831
Fast remains selected and the red message has reverted to the one shown in my earlier post (#57)

Sorry for saying 20H1. I should have said "Skip" which boils down to the same thing. At least your move From "Fast" to "Skip" has allowed us to learn something about the closure of "Skip Ahead" for now. This fact alone tells us that we cannot get to more advanced builds at the moment until MS changes the equation once again.
This Insider Program's cadence about the updates and their naming is getting more and more confusing with time, as MS keeps changing the rules of the game (metaphorically speaking). Sooner or later, we will find the real explanation and interpretation of this message in Insider Settings.

Thanks for the reply. I think I fixed it. I disconnected the drive and remapped it and I was able to to open it in file explorer. I'm going to try a restart and see what happens.

I restarted my computer and have tried accessing the mapped drive a couple of times and no GSOD. I bet that's why I was getting the GSOD when I did the Search hack to get the last release to install.

It would have been nice if MS had explained exactly what was the problem that was causing the rollbacks., but then pigs might fly.
