KB4556803 Windows 10 Insider Preview Slow & RP Build 19041.264 May 12 Insider

Hmmmmm?!
Odd thing about this Release Preview.
I have only the "needs optimization" bug, but damn, this build is stable.
I have had no errors or critical events in Reliability Monitor since upgrading.

Attachment 278882

Yeah there are events in Event Viewer, but those are for things that don't effect the system, or are just timeouts, or because something is either turned off or not present, no big deal if you know how Windows works

So I guess so far it is pretty rock solid.

Mostly stable except a couple of failed downloads, corrected later, and a failure of Firefox to respond. Only real issue for me is the inability to optimize drives with some semblance of a time table

If all of you people using slow ring and fast ring are having problems in VR with Defragmenting drives, what is this going to be like in Hardware? Actually you should not be using this in hardware yet. When it comes to doing this in hardware you should upgrade by backing up and reinstalling the newest version. That would fully defrag all of your System drives. I'm using SSD so no defragging going on.

Actually Windows Defrag is clever enough to know what it should do with SSDs. The real and complete story - Does Windows defragment your SSD? - Scott Hanselman

I am back to 1909 on my work laptop. Is defrag still broken in 2004 with the gui?

Yes.

Do you know where in the registry jungle the Defrag tools store their data?

Hello Toni,

What type of defrag data did you want?

The log file should be in Event Viewer > Windows Logs > Application, right click on Application, click on Filter Current Log, select Defrag in the Event sources drop menu, and click on OK.
