Windows 10 Search not working after performing an in-place upgrade

This article discusses a fix for the Windows Search bar / Cortana not working after an in-place Windows 10 upgrade.

The Problem

Upgraded Windows 10 to find Windows Search Not Working? The symptoms may include:

  1. Clicking on the search bar in the task bar does not launch the search user interface pop-up
  2. Opening the Start menu and immediately typing does not launch the search user interface
  3. When you click on the search bar in the task bar, Cortana momentarily appears on the ‘Apps’ tab in Task Manager and then exists
  4. Clicking on the search bar causes SearchUI.exe to launch on the Details tab in Task Manager and then immediately exit
  5. The search bar on the taskbar flickers, flashes on and off or even vanishes completely; leaving a display artefact.
  6. The Events Viewer > Application log records the following event under Event ID 1000:
Faulting application name: SearchUI.exe, version 10.0.18362.1, time stamp: 0x5c90179d
Faulting module name: SearchUI.exe, version 10.0.18362.1, time stamp: 0x5c90179d
Exception code: 0xc000027b
Fault offset: 0x000000000015bf3e
Faulting process ID: 0xb50
Faulting application start time: 0x01d5229682a57780
Faulting application path: C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe

In my case, the upgrade was from Windows 10 1703 to Windows 10 1903 and the user account was a Roaming profile (local profiles were all fine).

Am I the only person who is beyond fed-up with this nonsense? I digress…

Yes, no doubt you are equally frustrated with seeing Microsoft supports unhelpful and generic “run DISM’s Restore Health command followed by running SFC.exe /ScanNow[1]. Microsoft Product Support are just ignoring the problem and trying to encourage people for format the system by means of finding a zero-effort fix. This attitude helps no one.

The Windows shell is a mess. The Windows Modern App paradigm – while improved on 2015 – is still not in a fit state to be able to replace Win32. With these kinds of issues, is it any wonder that even in 2019 no one is writing Modern Apps? Microsoft themselves were forced to acknowledge this. Microsoft’s one success to encourage the use of Modern Apps has been to create a Win32 wrapper. Allowing Win32 programs to be released via the Windows Store. It says it all doesn’t it?

The Fix

As the search bar works fine for local users, the issue had to be profile, not system level (for anyone paying attention this rules out SFC /ScanNow and DISM).

Event Viewer tells us the application version involved as being “Microsoft.Windows.Cortana_cw5n1h2txyewy”. For a test user this happens to map within their profile to:


I then proceeded to delete data from within the directory until search worked. The culprit was the contents of the Settings folder. Clearly between version 1703 and 1903, Microsoft have changed a lot here. There has not been any settings migration through Windows Store auto-update as “Cortana” (Windows Search) is only upgraded during feature updates.


Automating the Fix

If you are experiencing the same problem. I have put together the following PowerShell scripts to solve the issue on both a per-user and per-system basis. The script does the following

  1. Searches for all Settings folders present beneath any version of Cortana on the system
  2. Attempts to kill the SearchUI process, if present
  3. Deletes the contents of the Settings folder and the Settings folder itself

The SearchUI process/deleted data will be restored the next time the search bar is clicked.


For the currently logged on user

$settings = dir $env:UserProfile\AppData\Local\Packages\Microsoft.Windows.Cortana*\Settings
$settings | % {Stop-Process -Name 'SearchUI' -Force; Remove-Item $_.FullName -Recurse -Force}


For a named user profile

$profile = ‘joe.bloggs’

$settings = dir C:\Users\$profile\AppData\Local\Packages\Microsoft.Windows.Cortana*\Settings
$settings | % {Stop-Process -Name 'SearchUI' -Force; Remove-Item $_.FullName -Recurse -Force}


For all users on the system

$settings = dir C:\Users\*\AppData\Local\Packages\Microsoft.Windows.Cortana*\Settings
$settings | % {Stop-Process -Name 'SearchUI' -Force; Remove-Item $_.FullName -Recurse -Force}


Things to note

Working search bars will have file locks on the Setting folder. If you do not wish to see file lock errors messages use:

Remove-Item $_.FullName -Recurse -Force -ErrorAction SilentlyContinue.


Deployment Options

Your options for deployment of the script(s) are:

  1. Inject the script into a HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce entry for the system
  2. Inject the script into a HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce entry for the user
  3. Process the script as part of a logon script
  4. Use SCCM to deploy the script as a SCCM Package to the system/user
  5. Fire the script as a one-off/recurring Task Scheduler script via Group Policy
  6. Execute the script at the end of your MDT upgrade task sequence

WorkFolders Folder shows Sync Error even though its contents are fully synchronised

WorkFolders allows you to perform policy based file HTTPS synchronisation between corporate servers and BYOD devices or teleworker devices. This article discusses a workaround to a problem where an anonymous sync error appears on a directory despite all of its contents synchronising successfully.

Outline of the Problem

Assume the following directory structure

C:\Users\CompanyUser\WorkFolders\Documents\WorkFolders Test

The following files/folders are present within WorkFolders Test:

WorkFolders Test\Problem Folder
WorkFolders Test\Problem Folder\File in Problem Folder.docx
WorkFolders Test\This file is OK.txt

Windows Explorer will display a Green circle with a tick for file/folder object that is synchronised and a Red circle with a cross for a faulted file/folder. After synchronising, the sync results will display as follows:

WorkFolders Test\Problem Folder [CROSS]
WorkFolders Test\Problem Folder\File in Problem Folder.docx [TICK]
WorkFolders Test\This file is OK.txt [TICK]

No errors are displayed in the Control Panel WorkFolders applet. There are no related errors in the clients WorkFolders Management/Operational Event Viewer logs. No relevant errors are present in the file servers SyncShare Operational/Reporting logs.

WorkFolders Error Screenshot - outer folder
The parent folder shows that its sub-folder has a sync error
WorkFolders Error Screenshot - inner folder
The contents of the error’d folder are however correctly synchronised.


Although WorkFolders is indicating that the issue is being caused by the “Problem Folder” directory. The issue is being caused by the “File in Problem Folder.docx”.

The following symptoms will be true:

  1. Renaming “Problem Folder” will not fix the issue
  2. Altering the filename of “File in Problem Folder” will not fix the issue
  3. Changing the “File in Problem Folder.docx” file extension (e.g. to .txt) will not fix the issue
  4. Opening and saving the “File in Problem Folder.docx” will not solve the issue
  5. Moving “File in Problem Folder.docx” out of “Problem Folder” will clear the sync error, but the error will immediately migrate to the new location
  6. Rebooting the client computer will not help
  7. Restarting the server will not help
  8. The file does not have any connected temp files or lock files associated with it in the client file system


There is nothing wrong with the file itself. It is not corrupt, pay-loaded with a virus or violating any policy. It is my (unproven) belief that the record for the file in the WorkFolders synchronisation database is corrupt. Performing any of the above steps will not alter the record in the WorkFolders client database, thus the problem cannot be ameliorated.


Fixing the problem

One you have identified the problem file(s). You can use one of the methods below to correct the error.

Save the file as a completely new file

  1. Open the file in its associated editor (e.g. Microsoft Word for docx files)
  2. File > Save as…
  3. Save the file in its original location, but with a different file name (do not overwrite the original)
  4. Delete the original file
  5. Allow WorkFolders to re-sync
  6. Rename the new file as required

This approach is easy for an end-user to perform, but can be very time consuming if you are troubleshooting a large number of such issues. It requires you to know which file is causing the problem in the first place.



  1. Compress the file using Windows Compressed folders (Right click > Send to… > Compressed (zipped) file)
  2. Delete the original file
  3. Wait for the folder to re-sync and clear the error
  4. Extract the original file from the zip back into the desired location

This method will create a new record in the WorkFolders synchronisation database and the error will not reappear. You can use the technique to fix an entire folder structure without having to first identify the problem file. It is also easy for an end-user to perform.


Move the file

  1. Move the file outside of the WorkFolders monitored file system. For example, move the file to C:\ or into the Recycle Bin
  2. Allow the original folder to re-sync and clear the error
  3. Return the original file to its original location and allow it to re-sync

Again, this method will create a new synchronisation record. In a managed environment this may be harder for an end-user to perform due to permissions. It is however easier for an administrator to perform as you can cut/paste the entire file structure out and then back into the WorkFolders sync root.

If you use this method, remember to move it to a location within the same drive letter. If you do, the move will preserve permissions, file dates and will not physically copy the underlying data to the new location (just update the MFT).

Unable to update NuGet or Packages in Powershell due to “WARNING: Unable to download the list of available providers. Check your internet connection.”

When attempting to install or update PowerShell Modules, NuGet or NuGet packages in PowerShell 5. You receive one or more of the following errors

WARNING: Unable to resolve package source ''.

The underlying connection was closed: An unexpected error occurred on a receive.

WARNING: Unable to download the list of available providers. Check your internet connection.

Equally, you may receive the same error when attempting to run a WGET or an Invoke-WebRequest command e.g.


You are unable to install/update the software component or make an outbound internet connection.

This issue may be especially prevalent on IIS installations serving HTTPS websites.

The Fix

Conventional troubleshooting is fairly well documented on-line

  1. Ensure that you are actually able to open a https webpage in a web browser
  2. Ensure that your DNS is working correctly.
  3. Check to see whether wget can connect to a non-https site e.g.
  4. Check to see whether or not you need to use a Proxy server. If so, you must configure PowerShell to use your Proxy Server before you proceed. This may require you to to configure PowerShell with your Proxy Server credentials.
    $webclient=New-Object System.Net.WebClient
    $webclient.Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials

A less obvious issue to explore related to the default operating system security configuration for using SSL.

More Info

By default, Windows Server and Windows client will allow SSL3, TLS 1.0, TLS 1.1 and TLS 1.2. The .net Framework is also configured to allow these protocols, and, by default, any outbound request for a SSL site will attempt to use SSL3/TLS 1.0 as its default protocol.

In secure environments, where system administrators have enabled recommended best practice on Windows systems to disable the use of SSL1, 2,3 and TLS 1.0. PowerShell is not currently clever enough to internally compare its configuration to that of the operating system. consequently, when attempting to make an outbound https request in such an environment. PowerShell will attempt to use one of the older protocols which has been disabled by the operating system’s networking stack. Instead of re-attempting the request using a higher protocol. PowerShell will fail the request with one of the error messages listed at the beginning of the article.

As NuGet and Update-Module both attempt to make connections to Microsoft servers using HTTPS, they too will fail.

Encountering this issue on a SSL enabled IIS install will be more common, as it is more likely that system administrators will have applied best practice and disabled legacy encryption protocols on these servers. their public facing, high visibility should demand such a response.

To fix the issue there are two options:

  1. Reconfigure and reboot the system to re-enable client use of TLS 1.0 (and possibly SSL3) via

    DisabledByDefault = 0
    Enabled = ffffffff (hex)

  2. Alternatively, you must set-up each PowerShell environment so that the script itself knows not to use the legacy protocol versions. This is achieved via the following code which restricted PowerShell to only using TLS 1.1 and TLS 1.2.
    [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]'Tls11,Tls12'

Create a Slipstreamed Hyper-V Server 2019 installation image with working Remote Desktop for Administration

If you have been following the saga of the non-working Hyper-V Server 2019 release from November. You may be aware that the most prominent issue – that of Remote Desktop Services for Administration not working – has now been resolved in the February 2019 patch release cycle.

This article outlines how to create updated media for Hyper-V Server 2019 using the original installation medium and patch it into a working state.

Note from the author

Please note that if you intend to use Hyper-V Server in a production environment, you should wait for Microsoft to re-issue the office ISO. Once it is released, it will be made available in the Microsoft Server Evaluation Centre.

View: Microsoft Evaluation Centre


You will need access to a Windows 10, Windows Server 2016 or Windows Server 2019 system in order to update the installer.

Obtain and install the Windows ADK 1809 (or later) selecting the Deployment Tools option (providing you with an updated version of DISM)
Download: Windows Assessment & Deployment Kit (ADK)

Retrieve the original Hyper-V Server 2019 ISO
Download: Hyper-V Server 2019 (1809)

Download following updates from the Microsoft Update Catalogue
Note: This is correct as of early March 2019. It is suggested that you apply newer cumulative and servicing updates as they are released in the future.

  1. KB4470788
  2. KB4482887
  3. KB4483452

View: Microsoft Update Catalogue

[Optional] If you wish to apply any language regionalisation (e.g. EN-GB), source the CAB file(s) for the language features that you require. For example:

Updating the Installation Image

To update the installation image:

  1. Create a folder on C:\ called ‘Mount’
  2. Add a second folder on C:\ called ‘hvs’
  3. In the hvs folder, create a subfolder called ‘Updates’
  4. Extract the entire contents of the ISO from the Hyper-V Server 2019 ISO into C:\hvs
  5. Place the three MSU files from the Microsoft Update Catalogue into the C:\hvs\Updates folder
  6. [Optionally] Place the CAB file for the language pack into the C:\hvs folder and for convenience rename it ‘’
  7. Open an elevated Command Prompt
  8. Issue:
    cd /d "C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64"
    To navigate into the working folder for the updated version of DISM.exe
  9. Issue:
    dism.exe /mount-image /ImageFile:"C:\hvs\Sources\install.wim" /Index:1 /MountDir:"C:\Mount"
    To unpack the installation image into the C:\Mount folder
    Note: Do not navigate into this folder with CMD, PowerShell or Windows Explorer. If you leave a handle open against this folder when you try to re-pack the install.wim, it will fail.
  10. Once the mounting is complete, patch the installation by issuing:
    dism.exe /Image:"C:\Mount" /Add-Package /PackagePath:"C:\hvs\Updates"
  11. [Optional] Apply the language pack by issuing (change en-GB to your language as applicable):
    dism.exe /Image:"C:\Mount" /ScratchDir:"C:\Windows\Temp" /Add-Package /PackagePath:"C:\hvs\"
    dism.exe /Image:"C:\Mount" /Set-SKUIntlDefaults:en-GB
    If you intend to use ImageX, DISM or WDS to deploy this image, you can skip the following command. If you intend to create a new bootable ISO or UFD, issue:
    dism.exe /image:"C:\Mount" /gen-langini /distribution:"C:\hvs"
    This will create a new Lang.ini file which must be included in the ISO/UFD media (but is not required for other deployment methods)
  12. Dismount and re-package the install.wim file by issuing:
    dism.exe /unmount-image /MountDir:"C:\Mount" /Commit
  13. Once DISM has processed the installation image, the new Install.wim file can be found at:
  14. At this point you will have a working installation image which you can use to create a new ISO, UFD or install via WDS. You should delete the Updates folder and [optional] from C:\hvs before creating a new ISO or bootable UFD.

If it goes wrong at any point, issue the following command to abort the process and go back and try again:
dism.exe /unmount-image /MountDir:"C:\Mount" /Discard

Delete the C:\Mount and C:\hvs folders once you have finished creating you new deployment media.

Final Word

If you follow the above, you will have not only a fixed RDP experience, but also a current patched version of Hyper-V Server. Eliminating a little time spent waiting for Windows Update to run.

If you are going to enable RDP for Administration. As ever, do not forget to enable the firewall rule in PowerShell. SConfig.cmd does not do this for you!
