  • Fixed issue where local user accounts weren't locked after a number of failed sign in attempts.
  • Improved support for video playback in certain apps that didn't render video correctly after resuming from sleep.
  • Fixed issue with Windows Phone losing user authentication certificates after upgrading to Windows 10 Mobile in some cases.
  • Improved support of the backup settings of apps on Windows 10 Mobile.
  • Fixed issue where Microsoft Silverlight based apps wouldn't install on Windows 10 Mobile after joining Azure Active Directory.
  • Fixed additional issues in .NET, Windows Kernel, Windows Update, authentication, revised daylight saving time, support for PDF files, Bluetooth, Microsoft Edge, Internet Explorer 11, networking, and Wi-Fi connectivity.
  • Security updates for Microsoft Edge, Internet Explorer 11, Kernel Mode Drivers, Windows Kernel, .NET Framework, Windows Secure Kernel Mode, and Microsoft Print Spooler.

Microsoft notes that "No new operating system features are being introduced in this update."

  • I'm NOT on Insider Preview and am getting it now too on my UK Lumia 950
  • The update applies for those not enrolled on an Insider program as well as Release Preview Ring
  • Yeah. Article's been sneakily updated to say that!
  • when u going to fix the god damm facebook app, people??? when??? is just an app!! 
  • Maybe you should use the Facebook (Beta) app actually published by Facebook like me. Has all the features you could possibly want.
  • For me on Surface Pro 4 Facebook app and Messenger both doesn't respond on touch screen events sometimes. When it happens I just can't use these apps.
  • Bummer
  • I don't think FB beta works with every phone. I'm using the 950 and can't download it.
  • You have to set your region on France, than download and than just switch back to your real region
  • Or U.S.?
  • Don't waste your time. It doesn't appear in the list.
  • The app is no longer available for download
  • Use the direct link from Windows Central article
  • Try with region set on germany. I have been using the facebook (beta) app (the one made by facebook) for about a month along with new messenger and both work great, faster then old apps, more features, stable. Thats all I want from fb apps. Now if only messenger would get call support
  • I have this app. It worked the first few days but then the app crashes when opening. I amgetting really tired on getting 3rd rate apps on my 3rd rate OS. Damn. I'm surprised I said that. Maybe I'm just sick and tired of being a loyal MS follower.
  • Facebook beta is a big piece of crap. It crashes on startup if u even get it to start. Slooooowwww. Omg people! How effing difficult is it!? Posted via the Windows Central App for Android
  • You could be the next WM dev rock star by finding out how effing difficult it can be.
  • I had the same problem.  Solution: Simply move the Facebook app to internal memory. No more crashes on startup.
  • Its a great app but its really buggy and takes a lot of time to load up. Almost always crashes the first time it loads. Hoping for a good bug fix and performance improvement update soon :)
  • And btw...no need to get angry
  • I'm on the Release Preview Ring and get these 10586.xxx updates on my Lumia 635 DS.
  • That's because it's for everyone
  • Same I got it on my Lumia  830 UK. I still have the bug that causes the screen to get stuck on the windows logo when it restarts everytime I have a update which is wierd. I rolled back from the Insider Preview cuz my phone got bricked due to that very same bug. I'll have to deal with it lol.
  • Updating my L925 right now
  • Lumia 925 getting this update? Or have u used xda hack.
  • No hacks. My Lumia 925 is on the Insider Release Preview Ring and gets all OTA updates for this branch.
  • Mine as well, still love my Lumia 925
  • x20 series can get treshold updates but not redstone. 
  • Correct
  • redstone only via xda hack
  • Is this for insiders only?
  • No.
  • What about dttwu on US 950XL? Why they take it too long to release?
  • Since that's a firmware update it's your provider that has a say in when you get it.
  • My phone is unlocked, carrier free.
  • I got it on my US 905xl couple of hours ago. Check it once again.
  • Daniel - Can you please provide a quick link on the site for users to refer what insider builds are what version is it currently on and what is latest production stable release etc., 
  • Search about it in Wikipedia under "Windows 10 Mobile" & For complex view - https://support.microsoft.com/en-in/help/12387/windows-10-update-history
  • Been trying to keep this up to date with just that info.   http://forums.windowscentral.com/windows-10-mobile-insider-preview/41960...
  • If this build is not for either insiders or release preview ring, then does this mean we should be expecting an Anniversary update build for the release preview ring? ☺
  • But it IS for the release preview ring. It's not for the slow ring or fast ring though
  • I don't understand the meaning of this build if the fast ring build is supposed to become anniversary update (RS1) for all the insider rings and production build!!!
  • The meaning of this update is to make stuff more stable and prepare it for the redstone. You peeps are complaining on everything. 
  • For everyone
  • Nope
  • Misinformation. All those on the stable branch of W10M get it.
  • Cumulative updates are for stable production releases. (10586.XXX). Insiders are in Redstone builds. This is not a Insider release. This has been mentioned over and over and over and over.  
  • +1, and it's the same EVERY second Tuesday of the month!
  • Nice, thanks.
  • Test
  • Stuck on 50% downloaded, Desktop version
  • Rebooted pc, now it's stuck at 2%
  • For how long? These update need time.
  • im waiting for almost half hour here thats the time it takes me to download almost 1GB file
  • Wow
  • Stuck 92% mobile version
  • Won't even download through Update catalog directly, stuck at 0%
  • Just relax...let it sit for a while. It will finish. My L925 took a bit but is done now.
  • You are getting impatient . . .
  • 30 minutes waiting for a download on 100MB internet connection isn't impatient it's a problem with the download
  • So, download PC version from MS Catalog OR wait for Anniversary Update
  • Great to see monthly security updates.  What other mobile does that?
  • Actually, Android did start monthly security updates recently.
  • To every phone automatically?
  • No. It's up to your service provider. If you have a budget phone, you can pretty much forget it.
  • My Samsung S6 gets monthly OTA updates too. And I believe Nexus devices too. Don't know about other brands.
  • My Note 5 is receiving updates for last two months...
  • all insecure ones
  • No I'm non insider lumia 950 XL DS
  • So the last Windows 10 build for my Lumia 720. Lumia 950 takes over the role :-)
  • I hope the battery is improved on mobile. After the last update I noticed my battery running down a lot faster than normal.
  • It depends upon your usage AND
    They didn't tell about less battery drain for this update...
  • My usage is not very high and it hasn't changed since I've used this phone AND sometimes a simple adjustment in the code can make things more/less efficient (an indirect effect - hence no mention of a "fix").  I simply stated that I noticed my battery running down faster than normal with the last update.  I don't see how that warrants a down vote?  Any ways, Cheers.
  • I'm in the same boat. Just yesterday my phone decides to go from 100% to about 30% in a matter of three hours without me even touching it. I have noticed it is something to do with Messaging+Skype. It was having very heavy use in the background.  Once I disabled background usage for it, the issue went away, but I also started missing skype messages.  Weird thing is that my skype usage is pretty even throughout the day.  It doesn't always happen to that extreme, but it's definitely the biggest battery drain on my phone.  It's an interesting problem I'd love to spend more time troubleshooting if I had, well, more time.
  • In short... Less Battery drain not fixed yet.That's why I only installed it on Mobile not PC yet.. Cheers ;)
  • I've already know the date of this update... ;)

  • I'd like to see an update that brings back the ability to install android apps Then we don't have to hear about Snapchat and Pokemon GO anymore lol.
  • iOS Bridge is the answer to your request, in theory all iOS apps will be ported without coding effort to Windows Mobile and this will allow companies to save costs by having 1 single developer team to support both iOS apps and Windows Mobile apps.
  • Actually the coding required is much more than you think. The iOS Bridge just gives you a head start for developing the full Windows app. With the Android Bridge, developers just had to replace Google APIs with Microsoft ones. This approach was much simpler but it involved putting an Android subsystem in Windows which was eventually removed due to performance issues.
  • Thanks for letting us know, I really thought it was the opposite, that iOS Bridge would require less coding efforts. It looks like Microsoft's Mobile team has a huge challenge to get iOS Bridge ready for 2017 Primetime, when new hardware by Microsoft is announced for Surface Phone.   
  • No ****! I've had enough of those. Posted via the Windows Central App for Android
  • But still no new firmware for US unbranded 950XLs lol
  • Yeah gotta wait on carrier
  • Carrier phones are "branded" phones. The new firmware is for all unbranded phones, like what I said mine was.
  • also dont have the firmware in 950 UK cv
     
  • Mine is unbranded also, OS updates are gonna come no problem,firmware still have to go through carriers or use Wdrt once it's on those servers
  • Nice, still waiting for the double-tap-to-wake firmware for my 950XL here in the UK though.
  • Call me a cynic but isn't that what every cumulative update change log reads? What am I missing here. Okay I'll contend with under the hood changes that makes my experience better (not).
  • This change log seems pretty specific and unique to me. And behind the scenes fixes can't be a bad thing...
  • Off topic. I would like to know what is Apple's opinion on letting iOS Bridge to port Pokemon Go for Windows Mobile, are there any legal issues which Microsoft ingringes on Apple's source code if they are using iOS API that can't be used outside the iOS ecosystem?  The reason I'm concerned about legal issues is that iOS bridge can become the salvation of Windows Mobile ecosystem by 2017 since Pokemon Go, Rovio and many other apps will be supported and carriers and consumers will be happy to get support on 100% of their apps, but in other web forums, some say Apple may not like this idea of having Windows Phone to circunvent a mechanism to run iOS code inside Windows Mobile.  I think this should be the responsibility of Windows Mobile team in charge of iOS Bridge.
  • An iOS API can only be used in iOS. Microsoft is making native APIs to replace the iOS ones.
  • No. A lot of the Apple API is open source and the bridge actually includes and uses it.
  • This has nothing to do with Apple. This has everything to do with app developers agreeing to use the iOS bridge to recompile their applications for use on Windows 10 UWP. Microsoft has simply coded .NET equivalent APIs that match the names of the iOS APIs so that when iOS source code is compiled in the .NET compiler, any iOS API calls are simply executed by .NET APIs.
  • Size ??
  • 77MB on Mobile.
  • Means nothing much really for mobile
  • For me it was of 722mb on mobile
  • downloading now.. thanks Dan.
  • sounds like the other past months list. they probably copy paste for the people who complain about no release notes haha. it's good we will finally get new features next month.
  • Downloading...I am also waiting for the firmware update for my unlocked Lumia 950 in US.
  • Would be an awesome treat if they brought back phone number links in emails and calendar!!! Please!
  • Oh hey this is nice. I've been spoiled with constant updates in the insider program so it's great to see my moms Alcatel one touch finally get an update.
  • Just 3 weeks for Anniversary, hang on.
  • Downloading now..640 dual sim India.. Stuck at 28%
  • Am I the only one, who whispered "I Want That Wallpaper" while reading whole article? XD
  • Doesn't seem much for mobile, what's the size though
  • Hey...can any one tel me why I cant get update of windows phone 10 update to my lumia 1320 in India..
  • Coz it's not officially supported
  • It isn't supported due to performance limitations. Download the stable build if you wish to by joining the Release Preview ring in the Windows Insider app. You'll get the same update that everyone else is getting, so no worries.
  • Yeah I've been running windows 10 on my L1320 since build .29 and works like a charm.
  • Oh..really...so when will I get it official support to Lumia 1320 india, any idea???....thank q "" windowbyddies625"..!
  • The 1320, 520,1020,920,820, and others agent supported do to a plethora of issues. So only stable builds will work, by joining the insider program. Redstone will not be pushed to these phones either. Lol I'm sorry bro, I had a lumia 928 that ran windows 10 mobile better than many supported devices, but that's just how it is.

  • My phone has stopped downloading at 57% and my Surface P4 has stopped downloading at 47%. Anyone else encountering this?
  • My PC sat at 57% for quite a while, but then it continued successfully. The phone update was applied with no apparent delays.
  • Thank q thank q "Akhil rockstar"...! Actually I'm a doctor so I dnt knw wel abt al these..! But I like windows OS...:-)
  • Miracast improvements? Don't mind if I do!
  • This update received but firmware update which came out few days ago still not.
    950xl unlocked UK. Its only me like that?
  • I have not had firmware update either. 950xl uk.
  • Same here. Can't have hit us yet, but eagerly awaiting!
  • My 950xl on release preview and its has lots of freezing and unresponsive live tile (tap on tile but it doesn't open the app). The major issue I notices after latest firmware update through WDRT. Not sure its caused by OS or firmware or a combination of both. Maybe I will get out of any of previews and use this updates.
  • What is fixed for mobile
  • Read the article!
  • Fixed issue where Cortana finally starts sending weather and sports card notifications again? I guess not. I might as well wait for the official Redstone release, hard reset (again!), and start fresh with my phone.
  • Works fine here
  • what about the constant freezes and reboots? I have sent them the issues and still. it's been happening since a few builds back.
  • No issues here on the L925 running this line of builds
  • PC Build.
  • Oh ok. I apologize. Sometimes I forget about the PC side. I can't vouch for this build on PC because my laptop is on the Fast Ring.
  • My PC is on the fast ring also. But from last nights new build 14388 I haven't had a freeze or reboot so, fingers crossed.
  • It looks like a hardware issue. I bet on the powersource ☺
  • That must be something particular to your install because in general Windows 10 Desktop is rock solid.
  • Updating now .. on my L635 (512Mb) and L520 ... Don
  • thanks for letting us know....
  • Is this the last Cumulative update for 10586 branch? since we will be having Anniversary Update next month.
  • Yes
  • Don't get hopes high on Anniversary updates, their main goal is to bring Redstone updates on PC's, they care much less about mobiles which are in production.... there is a possibility that we may not get an update at all on Aug 2nd. It may get delayed.... Has to see will MS keep its word or not....
  • The update will come on the 2nd. They wouldn't have announced a date until they were confident.
  • Its good if they release update on Aug 2nd but its better not to keep any hopes bcz if they postpone it like Win10 we start abusing them again....
  • They'll start rolling out the update on aug 2nd. That doesn't mean, you'll get it then. You might, but you also might not.
    If you don't get it on aug 2nd, that doesn't mean, the update didn't come out. :)
  • I am an insider fast ring build 10586.420 Lumia 920 and not having anything
  • Read the article carefully
  • You won't get anything on the fast ring for your 920 anyway. Fast ring is for RS builds and x2x devices aren't getting those. :/
    If you switch to the release preview ring though you should be able to get the last (few) th2 builds. :)
  • Downloaded in 5 minutes and now installing! Progress is done about 25% on the gears screen. Hope battery drainage is fixed on the Lumia 550!
  • WTH!  I have an Icon and have received an OS update twice in a couple of weeks!  I'm not used to all this activity!!
  • Can I get this on my Lumia 920 guys? with insider preview or a hack?
  • Why don't you just try it?!
  • How can i use insider preview?
  • You don't need insider preview. Its a regular update
  • My phone is a Lumia 920. I am not stupid. I asked if there was a way around microsoft not releasing updates for my phone.
  • You should be able to get it in the release preview ring.
    Download the Windows Insider app and choose the afore mentioned ring. Your phone may restart. After the restart check for updates. :)
  • Just finished installing.... Thanks Daniel!
  • Now, I'll just have to wait until August 2! :)
  • im using production build in my lumia 1020.i also downloaded now this build .494 if ever you experience stock your update to 50% try to turn of the wifi and closed the setting menu then turn on again your wifi and check the setting again and you will see become 80-90%downloading
  • Hows the performace in L1020? Battery life and stability?
  • moved back from insider to production.... everything fresh installation , I didn't used any backup..... so far mobile performance is good, has to see its battery backup, app crashes which were very frequent in last prod. build
  • im using lumia1020 and production build. now start downloading
  • Installed no issue on top of 10586.420 950XL dual sim unlocked USA.   Now just need that firmware upgrade and.....pokemon...yes i feel left out.  :(
  • Me 2
  • fix the damn data usage!!!!!
  • so true!
  • Downloading the updates know. Hope these updates don't cause the continual login boot loop other security updates have caused in the past. Looking forward to Anniversary update too.
  • No one called you stupid, I miss understudy. Use the inside preview. Chill out brush.
  • Hope my 930 stops heating up occasionally :)
