I recently cloned my Windows 10 partition from HDD to SSD.

I cannot open the Start Menu, Notifications, or anything that uses ShellExperienceHost. This includes things like the Calculator app, Edge browser and the metro style right click menu when you right click on an app in the taskbar.

Every time I try to open one of these, I get an error in the event log:

I have already tried:

  • Dism /Online /Cleanup-Image /ScanHealth

  • Dism /Online /Cleanup-Image /CheckHealth

  • Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

  • Deleting %LOCALAPPDATA%\TileDataLayer\Database and rebooting

  • Creating a new user

Short of refreshing Windows 10 and losing all my installed programs (I have a dev environment installed that would take a long time to replace), is there anything else I can try?

I am getting by with replacing the Windows Start Menu with Classic Shell, but it is quite annoying not being able to see the notifications area.

  • Sometimes waiting for the next build of windows via windows update cures issues, you might struggle with it until then, see if the next build corrects the issue. I consider W10 Beta software and is not stable on all hardware configurations.

  • This might work. In the APPDATA folder is a folder that starts with the name Tiled something. Delete it and reboot, and see if that helps.

I've been struggling with this for days and went through hundreds of pages of solutions. Nothing worked, until I hit this page, where at page 22 user PaulSturm recommended to run a repair using Tweaking.com - Windows Repair Free/Pro.

I was obviously very suspicious of this, but quite a few people said it worked for them and I was willing to try anything after spending so much time with this, thanks to Microsoft's despicable support.

You will need to install it, start the application, restart in safe boot mode when it asks and then run the default selected repairs. No need for the pre-scan, sfc scan or anything outside the repairs section (other than the strongly recommended backup and system restore point). It took about 20 minutes for me but everything was back to normal after a restart following the repairs. I don't know exactly which fix did it, but it's the ONLY thing that worked for me.

Again, I don't expect you to trust me on this, but there are quite a few people on that Microsoft page that vouch for it. Make sure you're comfortable with using this and do make a backup and a system restore when asked.

    +1. For me NO approach really worked. Even this. BUT, doing windows upgrade-repair via MCT restores shell* functionality partially: Cortana and ShellExp* still were reported as broken by troubleshoot manager and search didn't work, but at least the start menu showed up. At this point the windows repair tool worked and fixed the problem. It didn't work before I did repair-upgrade.

  • The error came in with one of the post 1709 updates. From this thread it's an issue not update version specific, but something likely wrong with the configuration of the current user. Dec 19, 2017 at 20:08

    This fixed both shellexperence host and action center and some minor issues. Still working today.

    Begrudgingly (shared same suspicions), this program fixed the problem for me. I ran it without safe mode, as safe mode was also broken (blurred image on login screen, no password box). The problem was fixed immediately without restarting, after it had completed the first 5 repairs. For me, the issue initially occurred after a RAM stick went bad, and it was isolated to the Action Center (notifications popout thing) not working, I did not have the issue with start menu, calculator etc described by the original poster.

Looking deeper at the problem, I was getting this error in the event log every time I clicked on the start menu

Faulting application name: ShellExperienceHost.exe, version: 10.0.10586.306, time stamp: 0x571afaa5
Faulting module name: Windows.UI.Xaml.dll, version: 10.0.10586.306, time stamp: 0x571af9f6

This event would appear after every time I clicked the Start Menu. I ran Process Monitor from SysInternals, clicked the Start Menu, and saw that ACCESS DENIED was showing for the User Accounts Package settings.dat for ShellExperienceHost. This file is located under:


(localappdata is the environmental variable for C:\Users\USERNAME\AppData\Local\)

I deleted the settings.dat file, clicked on Start Button, and it still wouldn't open due to settings.dat being deleted. So I renamed Microsoft.Windows.ShellExperienceHost_cw5n1h2txyewy (the entire folder) to .old and reinstalled the ShellExperienceHost UI App using the following PowerShell Command from an elevated PowerShell Window:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "C:\Windows\SystemApps\ShellExperienceHost_cw5n1h2txyewy\AppXManifest.xml"}

This then reinstalled the Local Package for my user profile, putting settings.dat back in place. Now no more errors and start menu is now working.

  • I had to muck a bit with these steps but I have a start menu again. (The creators update was required for VS UWP, which is what broke this for me)

  • If I run the first part of that (before the pipe), assign the results to a variable, and then look at the returned packages. ShellExperienceHost is not one of them. Aug 29, 2017 at 20:19
  • Also an issue with explorer and system handles on the folder. Restarting Explorer isn't best practice. This looks like a potential Mr Fixit script for M$S. :Hollers: Mr.Fixit! Why have you abandoned us?! Dec 19, 2017 at 13:49
  • But it worked after a reboot without the folder rename at any rate! Thanks Dec 19, 2017 at 14:45

After months of trying to fix this, I was finally able to by downloading a .img (like a .iso) file for Windows 10 for the exact build number that I had installed (Build 10240).

Once I had the right .img file, I was able to use it to do an in-place upgrade to the same version. Trying to do the same in-place upgrade to the latest version kept failing at 40% with error 0xC1900101-0x30018.

My start menu, notification center and Edge are all functional again.

Thanks to @magicandre1981 for all your help.

To see which file/registry key can't be accessed, run ProcessMonitor, filter for ShellExperienceHost.exe and look in the Result column which operation fails with an Access denied error.

Also try to run this update which repairs the ACL which also can cause the errors.

  • That ACL update sounded promising but did not fix the issue. Thank you though. May 17, 2016 at 20:37
