  • Win10 Anniversary Update bug turns into “Turn off Cortana” feature

    Posted on August 17th, 2016 at 10:31 woody Comment on the AskWoody Lounge

    Remember when we were talking a couple of weeks ago about the bug in the Win10 Anniversary Update that kills Cortana?

    Ends up that our idle speculation was correct – the registry setting that triggered the bug does, in fact, disable Cortana.

    NetDef posted the original hack (although he fingered BingSearchEnabled as the key, uh, key).

    Ed Bott just posted the definitive answer on ZDNet. In Win10 Anniversary Update, if you set HKLM\Software\Policies\Microsoft\Windows\Windows Search\AllowCortana to 0, Cortana disappears. Symptoms are the same as the ones I describe in my InfoWorld bug post from two weeks ago.

    If it were anyone but Ed, I’d approach the tip with caution — there are lots of hacks that end up breaking things. But Ed has the eyes and ears of the Dev team behind him. Count on this being a good hack. For now, anyway.

      This group polcy registry is known since first Windows 10 release in July 2015 🙂

      Great news. I have one question though. Does this setting prevent Cortana from running as a background process? When you “disabled” Cortana pre-Anniversary Update, it still ran as a background process.

      I believe it does – but if you can try it, I’d love to hear the results!

      By Jove, there it is! I’ve been wary of manual registry hacks. With Ed’s blessing they should be OK. (GPEdit has always been OK.)

      Hello woody,it seems that intel has fixed bluetooth problems with the famous patch:

      You can post it if you like in infoworld or here.

      I do not have the Registry key you suggest. Maybe you have to create it?

      But when Build 14393.10 made Cortana disappear on my TP, I sent you some screen shots. Here’s what I found:

      HKLUSoftwareMicrosoftWindowsCurrentVersionSearch
      BingSearchEnabled had been set to 0. Setting it to 1 made Cortana return. Either way, the search box in the taskbar worked, even there was no Cortana “O”.

      However, CanCortanaBeEnabled was set to 1. If it was instead set to 0, the search box appeared in the taskber but clicking it did NOTHING.

      I created the key and DWORD, set to 0.
      Cortana and Cortana Background Task Host still appear in TaskManager.

      Yes, you do need to create it.

      Wonder what the difference is between CanCortanaBeEnabled, vs BingSearchEnabled vs AllowCortana…

      Yep, I’m thinking of doing a roundup of the fixed and still-open problems. Maybe tomorrow.

      I haven’t got the AU so I can’t test just yet but I’ll take PKCano’s word for it. The trick I’ve been using this whole time is to remove execute privileges from searchui.exe and that seems to kill it completely, at least it does on 1511.

      (Blush) . . . I really can’t take original credit for what should be considered a bug. Pretty sure there were others that found it an hour or so earlier than I did when I did a WinDif on registry hive dumps between a working profile and a non-working profile re: Cortana.

      Anyway, here is what I “think” the differences are for the aforementioned registry key values.

      At the profile hive level: (HKCU)

      CanCortanaBeEnabled appears to be a hacky method (by MS) to store an internal check setting that controls whether the user can enable/activate Cortana. (This is part speculation . . .) I think it’s set to ‘1’ when a Local Only user links to a MS Account in account settings – or when a new profile is created directly with a MS Account. On a new profile that meets the requirements of using an online MS Account this setting appears to trigger the Cortana Setup dialog/wizard when the search bar is clicked.

      AllowCortana is the correct key to enable/disable Cortana for that profile – which only works on enable if certain other requirements are met — such as the user is logged on with a linked or direct MS account and whether Bing Search is enabled.

      BingSearchEnable is the key that was discovered to be set to the incorrect value during the upgrade from 1511 to 1607 on some profiles (no idea why yet) that “broke” Cortana. As far as I can tell, this is a BUG, and is not the “official” supported method to turn Cortana off/on. But it’s tied into the fact that Microsoft disabled the ability for Cortana to use any alternate search engine other than Bing. (I smell an EU antitrust suit in the making here.)

      As always I highly recommend the use of local machine or domain group policy to make any of these changes, which I know leaves Home editions in the dark. Hack the registry at your own risk folks. Leaving the umbrella of officially supported methods can lead to future unexpected (and very difficult to diagnose) problems on patch days.

      Off topic, but because I am still peeved about something:

      What can we do to pressure MS to restore the ability to turn off Consumer Experiences (aka pushing unwanted random crap-ware tiles onto a users start menu) in Windows 10 Pro by Group Policy?

      I don’t think there’s any way to convince Microsoft of the error of their snooping ways. I’ll continue to push back, but they’ve come to expect that. Even the EFF is now telling them that it’s a really poor choice:

      https://www.eff.org/deeplinks/2016/08/windows-10-microsoft-blatantly-disregards-user-choice-and-privacy-deep-dive

      But as far as respecting customers… I think we’re long past that point.

      No Cortana in taskbar context menu
      Search ocon is mag glass
      Search box says “Search Windows.
      Search bos settings still has Cortana language selection. History view, clear history, search online still options.
      No Cortana “O” in search box popup menu.
      When I type in the search bok I see activity in Cortana in Task Manager.

      This has me concerned. You set AllowCortana to 0, yet Cortana is running in the background (you can see it in Task Manager) and when you type in the Search box, the Cortana app is showing activity?

      Yesterday I was blessed (sic) with Windows AU on my desktop. So far I have encountered no major problems. I had MS Cortana turned off before and she stayed turned off. All of my other “turn offs” were also left off. The only visible change was the Windows Defender icon which is now a white shield instead of a fortress wall and the start menu shortcut for One Drive no longer works. One Drive has disappeared from Windows Explorer, etc., as well. I don’t use it so don’t miss it.

      A check with regedit showed that the HKLM key provided by Ed Bott was already set to “0”.

      I had Windows 10 installed almost since the Insider Program started. I went through all the iterations until November 2015 – release 1511 on my “production” laptop, imagine how much I trust my Windows skills to do such thing without backups. It was all good, but too much trouble with the betas, so after the 1511 release, I stopped the Insider program on that machine and stayed with the system with the regular updates until not long ago when I had enough and rolled back to Windows 7. Now you guys drag me back into Windows 10. What should I do now that Windows 7 is fully sorted for me (with your help for the last few months) and not challenging any more?

      Hmmm, Mac is the gold standard by far for end-users… but being a Mac expert is not paying as well as being involved with Microsoft technologies.

      If you’re asking about Linux, I believe Linux Mint is on Version 18, and I know Ubuntu Linux is on Version 16.04 LTS. Depending on your hardware resources, either of these Linux versions will keep you busy for a long spell.

      That’s probably because Mac doesn’t have as many problems to fix. I love my Macs. Windows in a VM!!!

      No, I am asking about Windows or other commercial product. Linux is good and solid for professional implementations like servers and virtualisation platforms where ease of use is not the main reason to be implemented. I made up my mind about Linux and if I have to use one distribution, that one would be based on Red Hat/CentOS and not what is popular today and may not be around tomorrow.
      Windows 10 has its own version of Linux based on Debian I believe right now 🙂

      Windows Subsystem for Linux in the AU is an Ubuntu 14.04 command line environment, not Debian.

      My daily driver runs Linux Mint 18 Cinnamon. After nearly 40 years of computing, 30 of them using every *nix system imaginable, I appreciate that LM just works, no fiddling. It’s certainly what I would recommend to any newbie or win10 refugee. I can count the number of problems I’ve had with LM 18 on no hands 🙂 Windows? Not so much, that’s how I ended up here.

      LM and Ubuntu have both been around for more than a decade and neither is in any danger of disappearing any time soon. You wouldn’t think that MS would be working with Canonical if they thought Ubuntu had an uncertain future.

      Ubuntu is built on Debian like Fedora is built on Red Hat.

      Microsoft has their own Unix version called Posix which was very much discontinued. Recently Microsoft wrote off Nokia assets in value of 7.2 billion USD. Was there any guarantee that when Microsoft bought Nokia, Windows Phone would be a success? Like any company which works with innovation, there are failed steps in the process.

      Actually, both Red Hat Fedora and Ubuntu are in the Debian Family of Linux distros. They share a common kernel and much common code, and can generally run the same apps.
