Windows 10: Announcing Windows 10 Insider Preview Build 14955 for Mobile and PC

I don't rely on Windows if I need to roll back to the previous build, but on a Macrium backup. Since I keep the last half dozen build backups, I want each as small as possible. I not only run Disk Cleanup, but CCleaner. Then I delete remaining files from AppData\Local\Temp, Windows\Temp and Windows\SoftwareDistribution\Download that aren't needed. Reboot, give Windows about a half hour to recover any files it didn't want me to delete, then backup.

 

Getting to it later, rather than sooner. Too many big deadlines this week. But the desktop got to the "Setting things up" screen without any help from me, and the Dell tablet is downloading the update right now. Desktop appears to be OK, I'll jump back in if any tablet issues manifest.
Cheers!

I have trieds installing this (and a few previous versions) but am once again stuck on a build (14926) as they all fail on second boot. After many tries with USB ISO and direct upgrade I got to 100% and it froze... then restored the 14926 again! GRRRR This upgrade process is so unreliable!

 

Habit, for me. No scientific reason. I'll stop, though, now that you point it out

 

It took me long to quit doing it myself*Redface
That and any other "cleaning", except, where something wasn't working properly or responding correctly.
And...
to feed the Browser Cookie Monster once and a while:

 

I had the option to update and close down last night, but chose to just shut down. This evening it updated successfully.

 

After a clean install of build 14955 syncing the time (Internet Time) to Windows Time or NIST fails. It's an annoyance to have to access the Control Panel using Settings but I can live with that.

The time sync problem is SERIOUS. Anybody else seeing this??

 

I have been getting an Access Denied each time I am trying to sync the Time on this and the previous Insider builds.

Screenshot showing this.

 

I see the same time update issue as well.

Control Panel is in Windows System on the start menu/screen as it has been and can be pinned to the start.

 

I have had an annoying issue with this build and also ealier builds (not in 14951 though). When I want to install a program and the UAC prompt rises, wanting me to accept that the program can make changes to my system, it just hangs there. Black screen. Only thing I can do is to hit the power button. I can't even send a shutdown command to the pc from another pc.

 

Anybody else have issues with WU failing here:

• Definition Update for Windows Defender - KB2267602 (Definition 1.231.531.0) - Error 0x80070643

I just installed Avast latest beta and will disable Windows Defender. Perhaps then I'll be able to get updates.

 

Why do you need Avast if Windows Defender itself is anti-virus program and can do same things?

 

No, Avast will not let you get updates. I believe it was an issues with the servers. I had the same error, then it went away.

 

If you took the trouble to read the release notes on #1 you would not have had this problem....see attach.

 

still no update
got last update 2 days after it was released so maybe it's the same this time
