How to fix Microsoft Edge crashing issue on Windows 10 build 14942

Windows 10 build 14942 for PC has been released to Insider through the Fast ring. The new update rolling out is part of the Redstone 2 update and brings some small features, improvements, and fixes.

However, we all know beforehand that installing early versions of Windows 10 from the Fast rings means higher chances of coming across bugs and features not working correctly. A good case and point is the recent Xbox sign-in failure after installing the latest Windows 10 Redstone 2 update, which fortunately Microsoft was able to provide a workaround.

Now on Windows 10 build 14942 a small number of users are reporting that after installing the latest update Microsoft Edge keeps crashing every time they try to open the browser.

While the company hasn't included this particular problem in its list of known issues for Windows 10, a workaround has surfaced that it seems is working for those affected.

In this Windows 10 guide, we'll walk you through the steps to prevent Microsoft Edge from crashing every time you try to open it.

How to stop Microsoft Edge from crashing at startup

Important: Before proceeding with this guide, you should know that modifying the registry is risky, and it can cause irreversible damage to your installation if you don't do it correctly. It's recommended to make a full backup of your computer before proceeding.

  1. Use the Windows key + R keyboard shortcut to open the Run command, type regedit, and click OK to open the Registry.
  2. Once the Registry opens, you'll notice the new address bar that lets you quickly know where you're in registry, copy and paste the following command in the address bar and press Enter:Computer\HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\Children
  3. Right-click each subkey (subfolder) key and select Delete.

  1. Click Yes to confirm the deletion and to complete the task.

Important! Do not delete the Children key, which will prevent Microsoft Edge from starting up, only delete the subkeys.

Once you deleted subkeys manually, you should now be able to launch and use Microsoft Edge on Windows 10 build 14942 without crashes.

You can learn more about the new features, and changes included on Windows 10 build 14942 in our dive deep article.

  • Awesome! I've also found that if you have malware bytes anti exploit currently running, deactivating it also allows edge to run normally.
  • I saw that posted here a couple of weeks ago. That fixed it for me.
  • What should I for Edge extensions not working?
    .
    Example: adblock plus is not actually blocking any ads, and Amazon Assistant doesn't show up even though it's installed.
  • Thanks! Edge started crashing for me on the previous build too and I had no idea why. Tried the method in this article with no luck even after updating to 14942. But after disabling MB-AE it works again!
  • A bit late. I manually uninstalled edge then reinstalled. Works but lost all my bookmarks
  • I did the same thing
  • What about the bug with Facebook's apps only showing a quarter of the window?
  • I'm seeing that one, too.  I primarily use the website anyway because the Facebook app is so HORRIBLE.
  • It's not the best but I prefer it over the site because my internet is so bad it cant handle loading page after page, plus performance is better and its just cleaner than the site.
  • That's happening to Facebook, Facebook (Beta), and Facebook Messenger apps
  • Sorry guys, but how is it possible to have this kind of problems when a update is released? MS should be more careful with this
  • Two Words... Insider Preview
  • Exactly.  Report bugs via the Feedback process.  I've given up wasting my time using that tell them about features I don't like or features I want them to add.  They don't care to hear what I have to say.   I just report bugs now.
  • Perhaps they have read your comments here. I wouldn't listen to you either after reading what you have written.
  • Really? There are several changes they've made from public opinion.
  • It's beta software. The people using it are meant to test it.
  • Hi Windows Central!
    This is irrelevant but...
    Today it's my birthday :)
    Don't you have a lumia 950 that you guys not use? :(
    I've been trying to win in every contest to have one of those beautiful phones, but I didn't won :(
    I can't move on from my lumia 735 because problems $$$ :(
    Hope you all have a great day. :)
  • Do NOT waste any energy on getting a 950.  My wife and I both have one.  It's a piece of junk, not even worth its currently reduced price.  Get a 650 so you get decent enough features without the poor performance and jacked up price.
  • Uh, right. The 950 and XL are both excellent phones.
  • Of course, I'm going crazy with the speed that I've seen on videos and the iris scanner looks great!
    Awesome phone:D
  • In fanboy land.  In reality land its slow,  shoddy build quality and mid range spec at best.
  • Wonder what land I'm living in then, because my 950xl is blazing fast with decent specs. Just because you've had a certain experience doesn't mean it's universal.
  • xl is much faster than the 950  but slow as &^*( compared to its competition.
  • It is actually the second fastest one according to benchmarks and a big test at one of our customers the employees found it to be faster than everything im the 810-era. Sorry.

  • but molasses compared to comparable era android and apple phones....SORRY!
  • Wow, that's hard to believe ScubaDog :( I really love both 950 and XL. For me it's like a dream phone. But maybe yes, it has some problems but I think that windows mobile is going up every day and will make the 950 phones a awesome thing. I need to try it out :(
  • My wife has a 950 and I the xl variant. I've had almost every Lumia at one time or another. The 950s are the best by far.
  • I have a Lumia 950 lying around that you can have. What is your address to send to?
  • Send it to me if you want... Here's my twitter handle: JediTWang, what's yours?
  • Rohan? My Twitter handle's JediTwang, I'll DM you my full address details. It's not my b'day, but it is my sick brother's b'day in a week, perfect gift! Like me he's quite interested in W10M, though doesn't have the $ lately. We're in Oz (Australia). Alternatively email = jedi_theone@hotmail.com  Best Regards, James
  • Yikes! that's a bit far. I would have been able to send it if you're in Canada or UK, but Australia is going to cost me a ton to send.
  • Postage is nothing to Oz for something that size, will gladly fix-you-up for it* via PP, where you, US? Cheers *inc. a small handling fee if you want
  • Look for yourself, for something of that size, the difference between Oz & Mex won't be hugely different. And as mentioned, happy to fix-you-up whatever it is (plus handling fee if you want).
  • .
  • I'll PM you in the forums my full address, & an e-mail you can use to send me your Paypal invoice. I'll pay it the minute you've emailed me it, so long as there's a brief explanation of how you arrived at the total cost. Cheers!
  • sorry to bring your hopes up but I was only kidding. I would only do it if you're nearby
  • Well Mex. isn't exactly nearby either, it might as well be the other side of the world, most def. not "local" to any US state. Please consider again, the differences should be negligbale between the two, I've sent you my PM in the forums. Best Regards.
  • Ah hello? A response to my PM at the very least (no matter what you decide), is the right thing to do: http://forums.windowscentral.com/private.php Especially if you were "only kidding" the whole time, and had no real intent to give anything away. I gave you all my details, & when one checks, it's apparent postage to Mex. isn't much less than Oz. And as explained, happy to cover all P&H, if you issue a PP invoice that breaks-it-down clearly. BR.
  • Yeah completely ignore, classy stuff... Says lots about a person's character when they routinely ignore people.
  • It would be AWESOME RohanRonQM this is my FB: Sergs Linares or my email account sergs_linares@live.com PD: I'm from Mexico buddy :S
  • Please post your address here.
  • Hi RohanRonQM, I've been reading above, and it's awesome if you can send it but, I don't want to bother you with the cost and all that. If you can, I will try to pay everything buddy. You can e-mail me to sergs_linares@live.com
    My address: México: CDMX (Mexico city). Magdalena Contreras, La Guadalupe, street: Francisco I Madero #123 CP:10820 I hope everything goes well.
    Have a great day buddy. :)
  • I had edge crash issue, I deleted all edge app files from explorer, then PowerShell to install package again
  • I'm still unable to open Edge on build 14936 (last week's) for mobile. Anyone know a work around for that?
  • Edge browser is one of the main thing in Windows 10 (that's how they promoted during the launch on 2015). After one year MS can't give a stable browser. Ashamed!
  • Right now, it's not launching for some people in a preview build, but Edge really isn't completely stable yet in the current stable release. Take for instance navigating YouTube videos with the arrow keys, which doesn't work like it should. But I guess it's only about a year and a half old.
  • Consumer would consider first stable browser, then performance. Edge is pretty fast in loading pages but unstable. even though chrome eating more ram, battery it is very solid. So peoples like us are sticking with chrome than edge. Google Chrome is still the king of browsers.
  • Chrome destroys the battery on Windows laptops like there's no tomorrow which is why I use Firefox instead.
  • People have the wrong mindset while using anything on insider builds. They compare a release browser like chrome to an pre release version of edge.
  • I used to use firefox but since it has been trying to become chrome i ditched it for edge. Edge is okay until the day wont upload an urgent document then you remember you are using microsoft products. Dont get me wrong I love ms I own ms all through but they have to get their **** together. And my next phone is android until they produce a worthy surface phone( but nadella doesnt seem like he will do it). Ask Cortana on edge is awesome and most useful tool on edge though.
  • Attention WinCen guys! I had this exact problem with Edge after installing the new build.  I found this much simpler fix for it on an MS answers thread.  Just open PowerShell, and paste this command into it: Get-ChildItem 'HKCU:\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\Children' | foreach {Remove-Item $_.pspath -Recurse} and hit Enter.  It does basically the same thing as the above method, but instantly and with less work - and less chance of accidentally deleting something in the registry that shouldn't be deleted..  
  • This blows up your favorites
  • This is an easy fix.  un install flakey, slow laggy windows 10,  and install smooth fast stable windows 7 or 8.   Your computer will run MUCH better...
  • And live in a deprecated world. Thank you, but no. I'm too young to leave the technology evolve while I stick with the old things.
  • ignore him, he's stuck in the flaky, slow laggy world of iOS and has nothing in his life except hating on MS.
  • see,  fanboy bonzeUK,  You can say things like IOS is boring etc,  but its NOT slow, flaky and laggy...thats for sure....It and MacOS blow the doors off windows 10 in speed and stability.  Please come down from fantasy land!  thanks...
  • Yawn.. Yeah pay double and do less. Yeah but brag like you do a lot more. That's what's up with the Mac guys. No touch, crappy for gaming.
  • He didn't say that iOS has more capabilities than Windows. Even myself as someone who doesn't like iOS or OS X (the newer product name is terrible) can see that both operating systems are overall more reliable than Windows, although when Windows isn't having problems, it's fast. Note that I'm talking about desktop Windows 7/8.1/10 and Windows 10 Mobile, not Windows Phone 8.1 and older which is probably more reliable than iOS.
  • Can we sync Microsoft Edge bookmarks with microsoft account that we used to sign on to pc/phone?
  • Yes, you can. Aside from the 10240 release all other versions allow you to sync bookmarks
  • As of Thursday Edge crashes every time I try to load my companies intranet site and it really pisses me off. I've used Edge everyday at my job to get my work done without issue until I came in Friday and all of a sudden it doesn't work anymore. Strange thing is the browser is just fine with any other site. I've tried everything! Nothing has fixed this BS. I even did the file deletion and PowerShell (supposed) fix, losing all my favorites. I'm at a loss and very frustrated. I will try the method this article mentions but I'm doubtful.
  • Why the chuff would you ignore the MS warnings and sign up for the Fast Ring on an important machine?
  • Who the F said I'm on fast ring. You're a f'n idiot!

  • When are we getting edge extensions on windows mobile?
  • Use Chrome.
  • MS Edge is my primary browser due to its fast, good font display. But recently its an headache for me when I open more than 2 tabs and switching from 1 tab to other it crashes a lot. I really like this browser but want to see a perfect browser like Moziall Firefox....
