Steps to reproduce

In Edge when you try to enter URL or search as soon as you type first character it starts selecting everything and drop down shows until you click another application. This behavior makes it hard to use Edge at all. This start about a month ago.

    • Hello,

      Thank you for providing this information about the issue. While typing, if you want to get rid of the auto-complete, then please press either Backspace or Delete.

    • Hello,

      If you wish to disable the feature, please go to the Menu (…) / Settings / View Advanced Settings, and under Show Search and Site Suggestions as I Type, toggle the switch from On to Off.

    • My Edge address bar also FLASHES (this is obscene) making me unable to type or search using the address bar. I tried disabling the Show Search and Site…, I did the sfc /scannow, I re-registered Edge… I did the DISM procedures, nothing works.
      I did a Safe Boot and found that the problem disappears, but then I don’t know which program is causing the interference.
      Any suggestions.

    • The issues isn’t the fact of “Show search and site suggestions as I type” or autocomplete. The issue is that once you type the first few letters of a search or url, the search and site suggestions begins flashing repeatedly and you cannot type your complete search term. In other words, the search bar in Edge (also Cortana/Win10 search bar) do not function.

      So if I search ‘Microsoft’ in the search bar, it will stop accepting any keystrokes at “micro” (where it stops accepting keystrokes depends on how fast you type), and the search suggestions begin flashing repeatedly without allowing me to complete my search. If I repeatedly click in the search bar, I will eventually be permitted to type a few more letters, but then the search suggestions will begin flashing repeatedly and prevent me from typing any more letters.

      I also disabled “Show search and site suggestions as I type.” It didn’t help. Of course, even if it did work, my preference would be to have Edge perform arguably its core/primary function without my having to disable features of the product.

      This issue began relatively recently. Perhaps as far back as May.

    • Matt H. is accurate in his description of the what the Edge address bar is doing. I cannot complete any input into the Edge address bar, because as soon as I type in a letter or number the address bar flashes and doesn’t allow further input.
      Microsoft needs to fix this.

    • I have exactly the same problem, Matt H. describes the fault well. It is so frustrating, I am going to install Chrome this afternoon as I can’t work with Edge anymore.

    • Same identical issue here and occurred after a recent update. Not sure if this was a major update which may have corrupted Edge.

      I did the obligatory sfc /scnanow with no issues found, the Pwereshell (admin) script reset (both ways) after checking the W-Firewall is set to automatic, blaa, blaa, blaa and the only thing left suggested was a corrupt profile – whoooraaa wants to do that!

      Did a major update on another PC (SURFACE) as well recently which would not even open a page in Edge. The same suggestions were made for that. I reset to the previous install and all was well again, but obviously w/o updates!

      Google Chrome for now until they fix this…

    • Following up on my prior comment: This issue has apparently resolved itself. I noticed the problem disappeared sometime last week. I did not alter any settings since posting my first comment here. The issue has resolved for the window search box as well as the Edge search box.

      Looking at my Windows Update History, I see Win10 cumulative update installed on July 11, 2017. Perhaps that contained the fix? But I think, though I am not certain, that I had the issue between July 11 and when I noticed the issue resolved.

    • In my case it was a McAfee/Windows Update conflict that that caused this issue. I uninstalled McAfee AV Plus and reinstalled. Instantly Edge & Cortana address/search worked fine.

    • Interesting, Laugh. My issue existed on my work computer, which does run McAfee. I did not have the problem on my personal laptop, and my wife did not have it on her Surface. Neither run McAfee. So that sounds like the likely culprit.

      My work computer is administered by an IT vendor, so it could be that he pushed through some kind of update recently that I do not know about.

    • Hi everyone… ‘Laugh M’ is right. I uninstalled McAfee LiveSafe Internet Security, reinstalled it, and Voila! The problem is fixed!

      I had been getting really frustrated with this issue for a month or so. It must have been from a recent big Windows Update, because everything was fine prior to that, and I’ve never had a problem with McAfee in the three years it’s been installed on my PC.

      Microsoft really needs to get this fix out to everyone, because just looking around online, it’s quite a common problem for anyone who has McAfee and uses Edge.

      Thanks, Laugh M… You saved my sanity!

    • You’re welcome John and great to hear my share helped.

      There is another similar issue where you can’t type anything in the address bar and Edge keeps closing. I found this on my Surface after a major W10 update, so tried all the suggested fixes, but in the end I rolled back the update and it worked fine again.

      I might give it a try again on that PC and uninstall/reinstall McAfee as part of the update was the addition of favorite/bookmark imports in Edge.

      I must admit, as a result of extensive Edge fix failures I tried Chrome and turns out I quite like, but still have Edge even though lacking confidence in it with future updates…

    • Yes, I now often just switch between the two depending on how I feel! Generally Edge is a tiny bit faster, but it can tend to freeze up a little more often for some reason. Chrome may be slightly slower, but it seems to hold itself together more…

      Thanks again!

    • Following up again. The problem came back a day or two after my last post saying it had resolved itself. Based on Laugh’s post, I uninstalled McAfee from my office computer and had IT reinstall. So far, the problem is fixed. So thank you, Laugh!

      IT is going to contact McAfee to see if there’s a patch they haven’t pushed out to the public yet. I’ll follow up here if I learn anything new from IT.

    • We experiencing this isssue too. We also use McAfee. But i would like to know which version of McAfee Matt H> is using. We are using McAfee Endpoint Security 10.5.1 with all the latest hotfixes

    • @Ronald v. - I was using Endpoint, but I do not know which version as it has been uninstalled for a couple weeks now. I have not had the issue since uninstalling McAfee.

      IT contacted McAfee support and reproduced the problem with them live. McAfee said, (1) Edge is not supported with the version of EPO Cloud my firm uses (we use the latest version available) (2) Microsoft must confirm and verify the problem before McAfee will consider working on or investigating the issue.

    • @Matt H. After removing McAfee and reinstalling McAfee we fixed the problem.
      Edge browser is working properly.

    • Has anyone had the “flashing” problem with AVAST software?

    • We are experiencing the same MS Edge address bar flashing & type preventing problem, but we use ESET Smart Security 10.1 antivirus. Uninstalling ESET and rebooting did not fix the issue. Out of 35+ PCs with the same configuration, only one is showing this symptom. If I can find a solution short of a reformat, I’ll post it here.

    • I also have this issue. I have this build (10.0.15063) on 4 machines total but the problem only appears to occur on my primary workstation in the office. The start menu appears to have issues, too, when I try and type a command (e.g. ‘mstsc’) where focus is stolen from the input control waaaay too fast to perform a search. I have tried disabling ‘send key’ functionality everywhere I can but nothing changes. Edge is effectively bricked on this computer.

      Please tell me the problem has been bugged and that a fix is in the works! :P

    • I have this problem too. (1703 15063.674) on my primary workstation (Surface Pro 4).

      Seems to affect Edge address bar and Start menu. I also notice that AutoHotkeys is much slower than normal when filling in fields.

      Uninstalling McAfee agent resolves all these problems.

    • You could try adding dllhost.exe as an exception in “Data Execution Prevention” under system properties > advanced tab > performance settings > Data Execution Prevention tab

      Turn on the option for "Turn on DEP for all programs and services except those I select and add the DLLHOST.EXE, depending on the OS you may need to add this from the default system32 folder, if this gives an error when doing so add the DLLHOST.EXE from syswow64

      If this rectifies the issues it is likely a policy from your AV agent trying to inject code into the .exe.

      Please note, if this works this is not a permanent fix. I would only use this on a short term basis to pin point where the fault is being generated.

    • This is the solution below that was posted at the top. I don’t think this feature was well planned because it makes edge almost unusable until you get to another search engine page. I contemplated switching to Chrome or FireFox until I found this solution. I am sure that there are many others who could not find this solution that made the switch. Perhaps a talk with the development team is required. Thanks

    • @Kevin M.: The solution you reposted does not work. See my July 5, 2017 post. The problem is caused by some interaction between McAfee and Windows. See the numerous other posts above. The only solution that works is to uninstall McAfee. McAfee refused to acknowledge the issue until Microsoft acknowledges it. See my August 17, 2017 post. It seems that Microsoft doesn’t care about the issue given the lack of follow up by anyone at Microsoft after giving advice that doesn’t work nearly 6 months ago.

    • It seems this problem is resolved in the latest version of McAfee Endpoint Protection - / Agent
      Since this was updated last week I have not had the problem with Edge.

    • @Steve E.: That’s good to know. I have not been running McAfee since July or August, and I probably won’t bother reinstalling it unless IT makes me do so.

    • I can confirm that fixes the problem. We have tested it with at least ten laptops. All of them didn’t experienced the issue after the update.

      In the releasenotes this was mentioned as a fix under threat prevention which was, as i believe, the issue.

      1191580 dllhost.exe no longer crashes after deploying a Sysprep image or performing a Cortana search on
      a Windows 10 Creators Update system when Exploit Prevention is enabled.

    • This problem has arisen on my old Dell laptop since the 1709 update. I have never installed McAfee but I do have Malwarebytes. I have this in the edge address/search bar and in the Windows search box. I have the December W10 updates installed. I will uninstall MalwareBytes and report the outcome.

    • Uninstalling Malwarebytes made no difference. I am using no other 3rd party AV software. Firefox is fine. Chrome is fine. Edge is rubbish and so is the windows search box.

    • I have issue in which when you try to type anything on the address bar and search bar on IE edge nothing is showing up. The only thing I found to fix the issue so that what ever you type show up in the address bar is by holding down the capslock key which typing the letters.

    • I am also having this issue in which the address bar keeps flashing when typing. The auto complete feature is off but I do have McAfee also installed. I am unsure how to locate which version I am using. I will try to uninstall and reinstall the program to see what happens.

    • Having the same problem here. Microsoft needs to fix this crap… Can’t search for anything as im cut off in my typing with blinking suggestions “with” them turned off in the menu to the right up top of my edge browser. Any news of Microsoft’s R&D working out a patch rebuild solving this junk to a decent usable internet browser?..!

    • I had this issue maybe some months ago with the 0patch client. The developer said it is some issue with the injecting. I reported it back ago through the Feedback Hub with a capture. But i don’t use the 0patch client anymore as it is mainly Enterprise targeted and doesn’t need it. I have no idea if the issue is fixed. Just posted this so others know about it.

      The feedback hub is the right place to report it guys, here it is for new features of the rendering engine only. Feedback Hub is for bugs and feature requests of the browser UI.

    • Saw where you said to report this issue with edge thru the windows feedback screen.
      It does the same thing, flashes and accepts no input.

    • I am having this same issue with the flashing address bars as well. it is affecting edge as well as my search bar in file explorer. I do not, nor have I ever had, Mcafee installed on this computer. This is also and issue that just sporadicall happens without warning, then will just randomly go back to normal when it feels like it. This is extremely frustrating, as I cannot access my files while it is happening, much less look up anything on Edge. Please tell me there is some other workaround than uninstalling Mcafee, because in my case it obviously doesn’t have anything to do with it.

    • Richey R., I hear your frustration. I had this Flashing issue a while ago, last year in July 2017. I did a lot of research and searching. When I uninstall McAfee, the flashing issue went away. I also realized I had other update issues that were caused by McAfee.
      I completely deleted my McAfee and all the Junk-ware attached to it. My computer runs beautifully.
      I use Windows Defender and IObit software to keep my computer clean and safe.

    • Edge is a total POS. I have the same issue, type one character in the address bar, it’s immediately highlighted and starts flashing. Cannot type anything else. All the suggestions in this tread do not work, McAfee has never been on this machine. Also, the Windows 10 message bar or whatever you call it, slides open and then immediately slides closed, can’t do anything with it, all suggested fixes online haven’t do anything. Conclusion: Windows 10 is a POS. I’m so done with this, hours wasted trying to fix this garbage …

    • You may think you don’t have MacAfee, but it may get installed with other programs or apps. When I’ve done Adobe updates they sneak in a MacAfee program…
      I uninstalled MacAfee, then searched my SSD drive and found many, many remnants of MacAfee.

    • You’re all hung up on this McAfee thing … IT’S NOT MCAFEE … just for giggles I ran the latest McAfee removal tool downloaded from the McAfee site, nothing, nada, no change Windows 10 is still a colossal POS and Edge still flashes the first character entered and refuses to accept any other character … if I didn’t value the hardware so much I’d take this machine out back, douse it in gasoline and light it on fire, that’s how frustrated I am … its a 4 core, 2.4mhz machine with 16gb RAM and a 1TB hard drive so there shouldn’t be any issues with the hard drive. So please get over the McAfee thing … that’s no the problem … if you or anyone else has any suggestions, I’m open to trying them. Thanks for the help though …

    • Sigh … not "issues with hard drive", “issues with hardware” … can’t even edit my post …

    • Can’t even add a new account to the machine, the new user dialog just keeps flashing and won’t let me type anything into the boxes … Christ what a colossal POS … have I already said that, yeah … guess I have and Microsoft wants YOU to pay THEM 100’s of dollars for support to fix THEIR colossal POS … they can just GFT … so done … and does anyone from Microsoft comment here … nope …

    • Im sure glad I migrated to chrome. Its fair till they get to work on these types of flaws “before” releasing it for market. Thats bad business. Small bugs are normal at times, but these major ones, Lol sure should be fired and rehired to a better developer replacing them. Heard rumor the operating system and its co tools like edge is on the back burner nowdays by a reliable source. True I say as they are more worried about their cloud technology focus vs. enough to have ALL R&D in their departments at ALL times paid to do so keeping EVERYthing working. Thats their job, and the high office flying the jet… Trust me. Save the pain, and go either Google’s chrome for a while maybe mozilla firefox. Stuff might change and most likely will be a very long time!..

    • Unfortunately I need to test our software with Edge as a lot of people will use it, otherwise I’d have nothing to do with it. I’ve been using Firefox for a while now, I’m all done with Windows Explorer/Edge AND Windows 10. I use windows 7 on my laptop and will not upgrade it to Windows 10 EVER. I’ll either wait until the next release of Windows and see if it’s any better, or suffer with Windows 7 once its unsupported. Windows 10 is just garbage …

    • Heard that one… Good luck.

    • I don’t have Mcafee, but this problem persists. One day it works fine and the next it does not. I am unable to get to the EDGE settings due to this issue.

      You really need an alternate location to set these settings in case the browser has problems.

    • Confirmed to be virus software related although why… is a mystery. I have Avast and I disabled and then rebooted. Edge worked fine after that. I removed Avast and just enabled Windows Defender.

      Edge is now working normally.

      Microsoft needs to work with the 3rd party venders better so these things don’t happen.
      I posted back to Avast about the problem also

    • Sorry Kenneth W, all I have on this machine is Windows Defender an even with THAT disabled, Edge STILL has the same problem . … drop the anti-virus thing, it’s NOT anti-vires (at least in my case) … still need/looking for an answer …

    • In our case it was combination Mcafee ENS 10.5.2 and the creators update.
      McAfee fixed it with version 10.5.3

      Below you find what caused the issue

      1191580 dllhost.exe no longer crashes after deploying a Sysprep image or performing a Cortana search on
      a Windows 10 Creators Update system when Exploit Prevention is enabled.

    • So Prescott C. It was a antivirus thing for us. So drop the arrogance saying it is not a Antivirus thing.

    • Ronald v. I apologize if my frustration with Edge and Windows 10 comes thru on my post, but it most definitely is NOT just an anti-virus thing and people keep insisting that it is.

    • Prescott C. It is a antivirus thing. Deinstalling McAfee fix the problem for me in the first place.
      But check you’re event logs for errors maybe you get a clue there.

    • Here is the technical document from McAfee what the issue was.

    • Solution for me was…
      I had this problem after the 1709 update on an old laptop (officially unsupported for Win10) where I think Microsoft update had installed a different glide pad driver. The problem was solved by installing a Microsoft wireless Mouse (dongle type). The glide pad then functioned correctly and all flashing in the edge address bar and on the start menu disappeared even when the mouse was not used.

    • Ronald v., it is NOT a McAfee thing. It started after the 1709 update and I never used any McAfee products before, recently I reinstalled 10 1709 and 10 1804 and this issue was on completely clear OS, without any additional software right after installation. Flashing the address bar in Edge, impossible to input any character there, flashing menus in Edge, closing right-button menus in Edge and Explorer, flashing menus in system properties, broken the Search button. So I was forced to roll back to Win 8.1.

    • Sergey. It was mcafee thing for me. It started for us with the 1703 update and Mcafee 10.5.2 It was fixed with Mcafee 10.5.3. So if you saying it is not a mcafee thing is totally wrong.

    • Nobody has answered the question. On any address bar and wwatch it flash, not able to insert any words to search. I have deleted programs to see if there is any conflict…none. Can not access any programs from the desktop…icons will start flashing. Any suggestions…thank you.

    • For most people on this thread it was an anti-virus issue, I have the same issue as you only no on all dialogs only those that I believe that use the Edge browser to access content or Windows 10 options. Microsoft wants to charge me (and everyone else) for support to fix THEIR issue, I refuse and have stopped using Windows 10, I’ve reverted back to Windows 7 for development. I’ve powered off my Windows 10 machine and will only power it back on to install updates that specifically address the issue. Windows 10 is a POS and I tell everyone I can to dump it. Hopefully the next version is more stable and Microsoft is willing to fix their problems on THEIR dime, not mine (or yours).

    • I have this problem in august 2019. I reinstalled Windows 10 using the built in software.
      My computer is almost useless because of the problems that OP described, among other things. But my problems is not mainly with the Edge browser, but with Google Chrome, and Windows 10 itself! I can’t use the search bar at the bottom left because it “autocorrects/autofills” what I’m about to write, and when it has done that I cannot do anything else. It marks the first possible option, and flimmers (!) like I’ve right clicked on it 3 times per second. The only way to get out of the start menu is to press the start menu icon at the bottom left again. This also happens in Google Chrome, which is weird. I left click the Chrome search bar, and it gives me a right click with a roll down menu that I cannot unclick unless I exit the program all together!


      FYI: I have tried 2 different mouses and keyboards, all seperately. I have also installed a fresh Windows 10 (but kept the files).
