UPDATE: June 21, 2016 – Microsoft has released a free repair tool for the Windows 10 START menu.  You can read very brief explanation and download it here.


It was a dark and stormy nighty in April when I installed Windows 10 build 10041 (on the fast ring) and the START button stopped working… ok enough fun.  If you have installed a recent Windows 10 build you may find that the START button and all of the modern apps either do nothing or error out with messages about .NET or PARENTAL CONTROLS.

In my case I just installed a free START menu utility (I like START 8 or CLASSIC SHELL) that you might have install on Windows 8, and waited for Microsoft to release the next build of Windows 10 that I hoped would be installed automatically as I am on the FAST RING.   It did not because Microsoft changes Windows Update to be a ‘Modern App’ which means it will not run.  Soooo, I thought was pretty smart to just download the build 10074 ‘.EBD’ upgrade file from a site and run through the conversion to .ISO and then do an in-place upgrade (which just means run SETUP from the DVD and tell it to upgrade).  That did work… for 3 days.  This morning my START menu was dead again, AAARRRG!

Microsoft needs to get its Application developer jobs to fix this but until they do, here are solutions that have worked for us:

1: Delete Corrupted AppLocker Files

The I found the fix:

  1. Right-click at Start and run Command Prompt as Admin
  2. Type command:
    ren %windir%\System32\AppLocker\Plugin*.* *.bak
  3. Restart Windows
  4. Be happy

Thank you UHLIK from THIS thread on the Microsoft Forum after reading THIS thread on the forum.


Another fix for the The Start Menu Does Not Work problem is:

  1. Right-click at Start and click RUN
  2. type SERVICES.MSC and press the enter key
  3. right click on APPLICATION IDENTITY and select START
  4. Be happy… a reboot is not required

3: Use DISM Command

UPDATED: August 19, 2015: A third fix I have used successfully is:

  1. Create a new user and log into it
  2. Right click on the START button and select COMMAND PROMPT (RUN AS ADMINSTRATOR)
  3. Type dism /online /cleanup-image /restorehealth
  4. Restart the PC
  5. Log back into the problematic profile hopefully you’ll find the store and apps work again

4: PowerShell Command to Reregister Packages

A forth fix I found came directly from Microsoft Partner support:

  1. Press Windows Key + R on your keyboard.
  2. Key in PowerShell and hit Enter.
  3. Right click on the PowerShell icon on the taskbar and select Run as Administrator.
  4. Now paste the following command in the Administrator: Windows PowerShell window and press Enter key:
    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
  5. Wait for PowerShell to execute and complete the command. Ignore the few errors (in red color) that may pop up.
  6. When it finishes, try hitting Start and hopefully it’ll start working.

5: Replace the “TileDataLayer” Database – Added Sept 24, 2015:

If none of these fix the Start Button, you can try our advanced solution to the Windows 10 Start Button not working, which has solved the issue for me twice already this month and you can read about it here. 

If you have had enough, you can just give up and REFRESH you machine.

  1. Right click on the START button
  2. Hold the shift key while selecting RESTART
  3. Select TROUBLESHOOT from the recovery menu

This will reinstall Windows 10 but it will keep all of your files (Documents, Pictures…) but it will kill all of the programs that have been installed.  Everything that is dead will be in C:\WINDOWS.OLD so you can fish out anything that is missing, but you will have to reinstall your programs, like Microsoft Office.

Many thanks! My start menu itself worked (as in, I could use it to sign on/off, power on/off, etc.) but none of my default apps like the calculator or alarm clock functions. The PowerShell fix (#4) worked perfectly with no restart necessary!

Katawan · February 16, 2017 at 1:08 pm

Solved with the solution n°3 thank you !

Roberto Guerrero · February 15, 2017 at 3:14 pm

Thanks a lot, After several hours without any positive result, item number 4 worked wonderfully

Khalil · February 10, 2017 at 1:29 am

Tried almost everything, all the tricks via powershell, regedit etc… etc.. – nothing helped except:
Run -> Regedit -> right click HKEY_CLASSES_ROOT -> Permissions -> Add -> Advanced -> Search -> pick both CREATOR OWNER and ALL APLICATION PACKS -> OK -> OK
Select CREATOR OWNER and give full access
Select ALL APPLICATION PACKS and provide read access
Apply and OK
no reboot needed
click start button and enjoy!
PS: excuse any incorrectness (made on the go translation from russian language), I’m pretty sure you’ll manage to get it right…

    Thanks Khalil.

    Your solution worked for me.!

    Thanks a lot

    Wow… U just saved my ass..thanks man

I recently faced this problem. About 10 minutes after a fresh install, all the above functionality (Edge, Start Menu, Calculator, Notification Center, Search, etc) stopped working. For me the troubleshooter mentioned Microsoft.Windows.ShellExperienceHost and Microsoft.Windows.Cortana were not installed correctly. None of the proposed fixes worked for me (creating new user account etc…).

SOLUTION: I finally traced it down to a conflicting NVIDIA graphics driver being automatically installed by Windows (for my external video card). After installing the latest driver update from the NVIDIA website (+restart) my problems were resolved and the troubleshooter completed without finding any issues…

So if none of the above works for you, it may be a driver related issue. Also mentioned here:

So #3 solved the issue with the start menu and Cortana. After trying multiple things, from using powershell to running a batch file, I’m glad that the menu is working now. The problem is that some apps are still not launching and appear blank. These apps include: Windows Store, Photos, stock Music app, stock games. Some stock stuff that wasn’t working before is working however: Start menu, Cortana, Edge, Settings, notifications, weather, calendar. What I can’t figure out is why this corruption happened in the first place.

One more SOLUTION – If no solution is working, as it was for me, try that:

Hope that’ll work.


    Ian Matthews · October 14, 2016 at 7:39 am

    Hi PP; “…delete the NVidia driver and reboot…” I have not heard of the video driver causing an issue with the START menu so I am glad there is yet another option for our readers with NVidia hardware to try.

Jestin · September 29, 2016 at 3:22 am

Thanks a Lot…Method one worked for me.

Mark · June 13, 2016 at 12:58 am

I have tried 2,3,4 but it doesn’t work. I like to try no.1 but I’m getting an error when I hit enter. I’m executing it in C:/windows/system32>. did I miss something?

    Ian Matthews · June 26, 2016 at 8:12 pm

    Hi Hermano;

    We could troubleshoot this but I think the brand new START BUTTON REPAIR TOOL from Microsoft will likely clear up your issue:

    Please let me know if this works.

Mushahid kazi · June 6, 2016 at 10:05 am

Hey Friends ,

I’m Mushahid, If you’re not able to open Start Menu, Action Center, Calendar & Batter Status in windows 10 then try this steps as given below.

1.) Log Off the user in which you’re not able to open start menu, action center, calendar & battery status.

2.) login to any other user and then press windows key + R Key (Open Run).

3.) Type this in Run “%LocalAppData%MicrosoftWindows” ( without ” ) then click ok ( Enter).

4.) One window will Open (popup) there you have to find UsrClass.dat & rename that file to UsrClass.dat.old .

5.) And then restart your system and login to user which u were not able to open action center, calendar & battery status. ENJOY

    hello sir, what if i only have 1 account?

      Ian Matthews · June 21, 2016 at 11:41 pm

      Try the START MENU REPAIR TOOL that MS put out today:

    Arya · June 11, 2017 at 2:40 am

    Thank you very much. Your approach worked for me.

Jim Norris · June 5, 2016 at 7:47 am

Unfortunately none of these are permanent fixes. Everytime windows does an update it blows up again on me. Come on Microsoft get a fix or I’m back to windows 7.

Bernie H · June 2, 2016 at 7:45 am

Fixed the missing APPS for a client with a more comprehensive set of PowerShell commands from
IMPORTANT: I did NOT run PowerShell as Administrator, the issue occurs with the User’s account and so should the fix.

Workaround: Edge Crashing With Roaming Profiles Enabled

It’s not necessary to add the Domain User as an administrator. You can use the following steps.

In many cases, just running the PowerShell script is enough:

reg delete “HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage”

Get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode -ForceApplicationShutdown ($_.installlocation + “\appxmetadata\appxbundlemanifest.xml”)}

$bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname

get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode -ForceApplicationShutdown ($_.installlocation + “\appxmanifest.xml”)}

    Mark · June 13, 2016 at 1:10 am

    1) Get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode -ForceApplicationShutdown ($_.installlocation + “\appxmetadata\appxbundlemanifest.xml”)}

    2) $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname

    3) get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode -ForceApplicationShutdown ($_.installlocation + “\appxmanifest.xml”)}

    Do I need to run this commands one at a time?

      Ian Matthews · June 21, 2016 at 11:46 pm

Katarina · May 20, 2016 at 8:25 pm

I had the same problem with my start button not working.
I did File -> Run New Task in Task Manager and browsed to C:\users\\appdata\local\ and deleted the entire TileDataLayer folder
And now I do not see settings is missing from Win 10 start menu.
PLS Help!

Mitch · May 5, 2016 at 1:35 pm

i wish I could find a reason for this. I have 10 PC’s all Dell t5500 Precision and I did clean installs on all of them and put Windows 10 on and two of them, once I install windows and finish, stop functioning with the start menu, nothing fixes it. When I clieck the menu the mouse cursor turning into the round circle then back to the mouse and I cannot get the start menu, search (cortana) nor the stuff on the right (action center) to pop up. But alas, everything else seem to work other than I can’t get to applications.
