Me too...in the end I re-ran my 17133.1 iso and tried again with the update and it installed fine...strange.

Failed with error code 0xc000021a each time previously.

This was on my main Windows...

Think the Insider Dev Team took an early Xmas break...Firefox audio and Setpoint issue main two for me. Rollback to 17046. Anyhow guess that's why we tinker with test builds!
Seasons Greetings...

Installed OK but no sound with firefox chrome is OK, TuneIn Radio etc OK very strange...anyone else with anything similar?

Me too...I just rebooted as it started to initialize 17017 then it downloaded 17025 on my 17004 build. Installed fast with no problems...so far so good.

Me too Kari...Using FCU on main partition with 17004 on Insider partition. Nothing I've tried allows me even to install this version.

Hopefully an update will soon arrive that fixes the obvious...

I've made at least 5 attempts and several through ISO all failed shortly after initial boot. Insider drive still on 17004.
Back on my main partition running 16299.19...oh well....

Had this problem too with Hyper V...decided to delete it completely and install
16226 on a separate partition. Better experience apart from the ongoing blurry text/scaling issue: At 125% device...

Thanks for your prompt reply...its late here I'll give it a shot tomorrow

Restarted from prompt box within settings>windows update inside virtual machine. Updated from within the VM as per any normal update...no ISO

Downloaded 16226 on my hyper V machine...awaiting restart so I restarted but booted into installed version: 16215. Its done this a half dozen times...not much experience of virtual machines, any...

Been using dpi fix for blurry text...was playing nice until this build now borked again.

Back to my Creators Update build :really:

16193 incoming...

124492

:really:

Dream on...XPExplorer sorts it though

Thanks, works for me too but the shortcut in Action Center doesn't appear to work anymore.

So many install issues...I always grab the ESD from Wzor and decrypt tool then install is a breeze plus you're in control of the whole process. Why put up with the heartache?

Main feature I use as...

Build 14951: Oh well...Start still reluctant to open and my PC blue screened so quickly I had trouble changing boot back to Anniversary.
Safe Boot did the trick in the end. Both installs exactly the...

Can't disagree with you...faster than Anniversary but it appears to have critical bugs.

Both my set ups are the same but Insider Start Menu is buggy, Setpoint crashes and Task Manager is buggy...

Come on MS...pull your finger out. We're all fans but this build seems rushed out!

Are you Samsung in disguise?.... :really:

I forgot that one...yup, me too. Bit of a dog all round really!

Me too...also start menu will fail to open for several minutes after a reboot.

Installed 14946 twice now still a problem. Also Setpoint (Logitech) crashes. Back on Anniversary!!

This is the OEM version of the 960 EVO 256GB: http://www.novatech.co.uk/products/components/harddrives-internal/ssdsolidstate/pciexpress/mzvlw256hehp-00000.html

Its in the basket...ready to pull...

Just installed and can't choose an account picture :really:

Boot on main partition is 7secs from windows logo with insider at least double that...would have thought it'd be faster not slower!!

Does anyone find that boot times for this Insider Build are noticeably slower than for the main Release Build?

I'm running a couple of SSD's and Insider is considerably slower...makes me wonder if...
