Windows 10 PC and Mobile preview build 14915 released for Fast ring Insiders

Microsoft has released the latest preview build for Windows 10 on both PC and Mobile for Insiders in the Fast update ring.

The roll out of the latest preview build will have the version number of 14915. This is just the latest such update for Insiders member since the global rollout of the Windows 10 Anniversary Update for both PC and Mobile earlier this month.

Windows Insider head Dona Sarkar has posted what's new and improved for PC and Mobile users in this latest Windows 10 preview build

Improvements and fixes for PC

  • We fixed the issue with being unable to use the power button on the Start menu.
  • We fixed the issue causing Cortana's text to speech capabilities to not work. Cortana should be able to read text messages out loud for you, tell jokes, sing, or give verbal prompts as expected.
  • We fixed the issue causing the Settings app to crash on certain editions of Windows 10 when navigating to different settings pages due to a missing .dll file.
  • We made a number of improvements to translations, including fixing an issue in Windows Update where it would say "your phone is up to date" in French when confirming that your PC was up to date.
  • Changing functionality via Settings > Update & security > Windows Insider Program such as your ring settings should now work again on this build. For more information – see this forum post.
  • We fixed a compatibility issue from a recent platform change that causes apps such as Yahoo Mail, Trivia Crack, Google and the Skype Translator Preview app to crash.
  • We fixed an issue resulting in some Insiders experiencing a delay in Mail notification toasts appearing.
  • We fixed an issue where the "Open with" dialog's "Look for another app on this PC" link wasn't working if the dialog appeared after using the "Run" dialog to open a file with an unassociated file type.
  • We have updated the Connect flyout so that the clickable area for each device listed now spans across the full width of the flyout.
  • We fixed an issue where if a Chinese Input Method Editor is active it could result in logging in to not succeed after device goes into and is woken up from Connected Standby.
  • We fixed an issue where for certain websites in Microsoft Edge, using CTRL + A to select all text and then copying it and trying to paste it into Notepad wouldn't paste anything.
  • We fixed an issue where importing favorites into Microsoft Edge from Internet Explorer would fail if the Favorites folder had been redirected to another folder, for example "C:\Users\ [[ user ]] \Documents\Favorites".

Improvements and fixes for Mobile

  • We fixed the issue causing apps to get stuck in a pending state if you move apps between a SD card and internal storage (either direction).
  • We fixed the issue causing Cortana's text to speech capabilities to not work. Cortana should be able to read text messages out loud for you, tell jokes, sing, or give verbal prompts as expected.
  • Changing functionality via Settings > Update & security > Windows Insider Program such as your ring settings should now work again on this build. For more information – see this forum post.
  • We fixed a compatibility issue from a recent platform change that causes apps such as Yahoo Mail, Trivia Crack, Google and the Skype Translator Preview app to crash.
  • We made a number of improvements to translations, including fixing an issue with Store app install notifications, where the wrong verb was used in German when letting you know to check out the app.
  • We have updated "You need to fix your MSA" notification toast logic, so it will no longer notify you multiple times in quick succession.
  • We fixed an issue where examining Microsoft Edge's advanced settings would result in subsequent downloads in Edge saving to the default locations, rather the preferred locations set under Settings > System > Storage.
  • We fixed an issue for Continuum-capable devices that could result in being temporarily unable to connect to a previously paired Windows 10 PC.
  • We have updated the settings for sounds so that .mp3 or .wma files downloaded straight from OneDrive or copied from File Explorer to the phone's Ringtones folder will now display automatically in the list of available sounds for ringtones, alarms and notifications.

Known issues for PC

  • Adobe Acrobat Reader crashes when you try to launch it.
  • You may experience a black screen when signing out and switching to another user account and will be unable to log in to that account. A reboot of your PC should allow you to log in to that account. Bash may not work after upgrading to this build. To get it working again, go to "Turn Windows features on or off", scroll down and check "Windows Subsystem for Linux (beta)" and click ok. After a reboot, Bash should work again.
  • The Settings app may crash when going to Settings > Personalization.

At the moment, there are no know issues for the Mobile version of this latest Windows 10 preview build.

  • Ooh fresh download now for my Lumia 650 and pc later
  • Guys no known issues for mobile...Yeah...Might we have to find few if there are any left...Lets squash them all...
  • Gotta squash em all! PokePC!
  • Certainly I still have problems with messaging, that the message send freezes and you have to wait up to a minute to be able to send another text. Already put in a bunch of tickets.
  • That part took me by surprise. No known issues for mobile? Or maybe those are Coming Soon :) Pretty excited though, loving the current build and this one seems like it will be quite nice.
  • It took all of us cynical ba$tards by surprise.
  • Issue 1 found: After scrolling action centre all the way down it doesn't go away when scrolled up from the middle of the screen.. Gotta grab it from the bottom and throw up to get rid of it... :'(
  • I've never even known that was possible to begin with
  • I agree.
  • Thank you!!! I thought i was imagining things. Its now like the way it was on 8.1 you need to pick it from the bottom, so annoying.
  • How is your progress going on? I can't wait to install this build, If you have find any issue plz dictate it here.
  • Seems like after updating I can't add a veiw all of my reminders within Cortana on my 950
  • Yep... You are not alone. Reminders are not working. You can add, but then you can't open them.
  • Same here, I can't even add a reminder. It just crashes cortana app when I click on reminders. Loads of other issues on this build too.
  • Can you share your experience with the build? Also, does your phone lag? My 650 lags on anniversary update.
  • I have 640 xl last build i have updating problem and from store does it solved in this build
  • Hopefully. I had the same problem on my 640. It's related to the sd card and internal storage problem they mention so hopfully that fixed it. It wouldn't update certain apps if you had set the default save position for new apps to SD card. Older builds usually told you that the app had to be saved to internal storage and asked if you wanted to overwrite the setting for the app involved. The problem appears to be that the new build doesn't do this anymore. I had to change my app install location setting to internal to fix the issue.
  • Yaaaaggggaaaaa
  • Also downloading on my beautiful Lumia 650.
  • How is the phone?
  • Perfect for that money, I migrated from Ativ S and this one is much better with the similar specs. Design, display, thickness, premium feel in hand ... gorgeous!
  • Like others said, perfect for that money. The only downside I experienced is stuttering notification centre on start screen, seems to be fixable but dont know if MS is aware of it.
  • I usually just show selected banners but disabled nearly all notification in action centre...
  • It's a great device
  • Please write your experiences later when you try it. Good luck :)
  • Shout it out in feedback app
  • downloading on my 950XL and SP3 :) Happy camper here :) eager to read a changelog =)
  • Yeah, I'm hoping that the Cortana voice response and text reading features are back. I have *really* missed those the last few weeks on build 14905.
  • Yep, and the start menu to shutdown is hopefully fixed as well
  • If you take 2 minutes to read the article you would see Cortana text to speech and shutdown issues were fixed
  • those comments were written hot of the press when the changelog wasn't published here yet :)
  • My bad :( downvoted myself if that's even possible
  • No worries :) all is well.
  • Crickey! Research is king! Also, if you take "2 MINUTES".........
  • Me too, so annoying having to right click start to shut down
  • Yeah. I wish we had the friggen Cortana in our market to even begin with...
  • Which market is that, out of interest? With the Anniversary Update, Microsoft made it a lot simpler to choose a supported region and stick to your preferred language dialect. I know it's not quite the same as having Cortana truly localized, but it's better than nothing at all.
  • Glad to see her back...
  • She runs around in the forums mostly.
  • Jessicator: Is that really you in your avatar?
  • Downloading on 950LX but will delay on the SP3 after you post a review. :)  
  • Always good to know that there is someone out there who has the same devices as i do.
  • Change log please. Im excited lol
  • Here's the change log

  • Pulling it down!
  • Ohhh. Hope this fixes my auto dim and lock screen issues
  • Not just me having those issues then.. I'm Nokia 950 xl on release build though
  • Nope, It's slightly improved on RP, or rather it got worse on Fast... I rolled back to that from Fast cos it was killing me.
  • This has been an issue for me since the launch version of windows. I have to reboot my phone a few times a week to get brightness working.
  • Nice, been waiting for this news. Downloading as soon as I get home. Can't wait to see changelog :-). Had the SD card not recognised issue return and also a new one whereby the action centre goes crazy loading all notifications at once. Minor things in the grand scheme of things tbh.
  • Certainly minor, but when that reload all notifications at once thing happens at 3 in the morning. The noise... Oh, the noise!
  • Lol, mine is set to vibrate so I don't get the noise but man its a shock when you access the action centre first thing you when wake up and the phone feels like its going mad.
  • My Mrs had hers on vibrate. That was an awkward conversation at 3am!!!
  • Well, *that* escalated quickly!
  • Lols
  • Go to bed!
  • Ggg
  • Ggg
  • You spelled egg wrong. Hth.
  • Its downloading on my lumia 540
  • Finally!!! Man I missed using my Surface 3!
  • Hope this fixes my outlook settings out of date issues.
  • What about battery draining problem solution, my Lumia 1520 automatically switch off when battery below 50%
  • Exactly same has started happening to my phone L1520 (from two builds earlier)... Not sure if thats OS fault or battery hardware fault
  • I am using Lumia 1520 green. Phone started shutting down abruptly on build 14915 and it's predecessor 14905! Phone would not turn on thereafter. It would turn on only after I connect to power. To my surprise, remaining battery percentage is 30-85 depending on the day. It looks like OS bug but only way to tell is to replace the battery with a new one. I wouldn't replace the battery until I try next build.
  • My lumia 1520 having similar problem. It would say Goodbye sometime before going dark and sometime it would go dard w/o any message. I doubt it is a battery issue becasue I see phone has enough better level after I connect to power. Hope Microsoft is listening this.
  • No new features is really disappointing :-(
  • It first gets core updates than new features and makeup changes.
  • Hmm... Ok. Let me wait for the landscape start screen. I'll jump into fast once I see that....
  • Yeah! Would really like to have landscape notifications menu. I mean they show up in landscape but you can't pull the shade down - it's crazy!
  • I assume the guys who down vote won't install the update if they see any new features since they don't need it.
  • Stop worrying about this website downvotes xD its just some fanboys who can't handle that some people have high standards xD ​Let the downvotes to my post begin :D Hoping to get to -100 :D it would get me really proud! it really would :D
  • I have standards. They are probably the same as yours. That being lower than a rattlesnakes' arse. ;-)
  • New features = new bugs, lets first deal with the ones we have before adding more problems
  • Yes, Cortana issue solved, and no known issue. Looking forward for this. Love 14905, ready for 14915.
  • Yeah new update....i miss this....everytime I update I feel like I got a new mobile
  • I hate battery issue, still problem not resolved
  • Battery issue is one of the biggest issue
  • Until n unless if it will not resolved soon I change my Lumia 1520 into iPhone 7
  • Okay, thank you for letting us know. We were all on the edge of our seats waiting to see if you were going to an iPhone 7. Have fun :)
  • My xl battery does a whole day now, and sometimes a day and a half at a push! As for kicking off about the 1520, maybe its knocking on now. Batteries have a finite life you know, just like iPhones. You gonna diss your nice 7 in 18 months when it happens again?? I had a 930 from new and the battery was shocking!! I didn't run off to the latest 'fashion' icon just because everyone else has one. And yes, I do use iOS an iPads.
  • Lumia 950XL stuck at 41% for the past 10 mins
  • Stuck downloading at 66% last 20 minutes.
  • Stuck downloading at 0% last 30 minutes because I haven't pushed the download button yet.
  • That's a known issue no. 1
  • "At the moment, there are no know issues for the Mobile version of this latest Windows 10 preview build." You must be kidding me.
  • What about fast battery draining issue by the way latest update come few mins before than how can you say it has no issue
  • Maya is quoting the article. Hence the speech marks. Also the part about no bugs is what MS have said. Of course there are new bugs hidden in places... It's just MS aren't currently aware of them
  • Nice one @shadowwolf. Someone who understands the insider deal. Do we 'have to' go through this every damned release
  • It clearly states on the disclaimer but im guessing people dont like reading
  • They have a great sense of humor :D
  • The give away there is "at the moment". How would they know until we get our grubby little mitts on them? We always find something, that's why we do the insider thing.
  • Wait, no known issues for mobile??? Does this mean it's PERFECT??? Let's find out...
  • No known issues means next build is new features? :)
  • Is the bug for custom message alert tone fixed in this build? Please confirm, anybody. I will definitely move to this ring if it is.
  • Downloading on 950XL.
  • 5GHz wifi does not work if airplane mode is turned on or there is no cellular connections on mobile build. The problem has been a few builds already
  • WiFi, 2.4 or 5ghz wouldn't work if in airplane mode. I have had no cell signal and still had WiFi. Strange.
  • Downloading............
  • Preparing to install updates 5% on Lumia 640 XL  
  • Size
  • Although I'm glad to see it fixed Cortana, it did NOT fix the problem with renaming tile groups.  Start just crashes every time you try.  I see this on five different devices.
