What causes Event ID 454 error in Windows 10

Windows Esent

As part of Microsoft Windows 2000, the ESENT transactional database engine was first provided to developers and has been available ever since. Structured or semi-structured data can be stored using ESENT if you need high performance, low overhead, and reliability.

This error usually occurs in one of three scenarios.

Mdm Configurationmanager Caller Did Not Specify User To Impersonate To

The caller failed to specify the identity of the user that he wishes to impersonate. The targeted user sid was (NULL), resulting in the error code 0x86000022, indicating an unknown error in Windows.

Mdm Configurationmanager: Command Failure Status

Windows Event Viewer contains the following information about enrollment status:

What Is Esent

All Windows versions since Windows 2000 have included the Extensible Storage Engine (ESE) as ESENT.DLL. As soon as you log in to Windows 10, you get the ESE Runtime (ESENT). Microsoft moderator says it is capable of searching and indexing a media catalog in the operating system.

I configured several custom configuration profiles in my Demo tenant, including some of those settings, to configure Windows 10 devices by Intune. Microsoft is adding more and more configuration service provider (CSP) settings. On this site, I set up a custom policy to block Third Party Suggestions in Windows Spotlight. I assigned the policy below to a user group.

In Windows 10, Windows Server 2016, or Windows Server 2019, new users log on to computers using the default profile that you create and activate.

The following problems may occur in this scenario:

  • The desktop displays icons slowly.
  • Microsoft Edge and Internet Explorer perform poorly when launching or browsing.
  • In this event, there are ESENT errors (database transaction tool, available to developers since Microsoft Windows 2000) that appear.

The event log ID is 454 taskhostW: (pid) webcachelocal: ‘Restore database with unexpected error -1907’.

The full event log message may also indicate an assignment to a location other than the user directory, such as C: UsersAdministrator.

Source Esent

You can access the full set of ESENT features using the Microsoft.Isam.Esent.Interop namespace included in EsentInterop.dll.

Here’s a recommended fix for the error Event ID 454, if you experience performance issues with user profiles.

The hidden files must first be viewed before you can begin.

Event 454 and 809 gave me an unknow Win32 error, but event 824 gave me: Per user policy has device wide scope specified. The policy was assigned to a device group, first I removed that group and assigned an user group. Nothing changed. I started searching on Google, but nothing pointed me in the right direction.
After a while I realized I deployed another Experience policy (Experience/AllowWindowsConsumerFeatures) to block some consumer features on all Windows 10 devices. I compared both OMA-URI`s:
./User/Vendor/MSFT/Policy/Config/Experience/AllowWindowsConsumerFeatures
./Vendor/MSFT/Policy/Config/Experience/AllowThirdPartySuggestionsInWindowsSpotlight

These steps will show you which files are hidden:

  1. The File Explorer can be opened by pressing Windows + E.
  2. Select File, then Options in File Explorer.
  3. To view hidden files and folders, switch to the View tab.
  4. (Recommended) Remove the checkmark next to Hide protected files.
  5. When the problem has been resolved, you must select both options again.

As a next step, follow these steps:

Log in to each affected computer

The following hidden files and folders can be accessed and deleted by logging in with a user account with administrator privileges on each affected computer:

Tip: WebCacheLock.dat and WebCache are the files and folders to delete, respectively.

  • DefaultAppDataLocalMicrosoftWindowsWebCacheLock.dat – WindowsWebCache in C:UsersDefaultAppDataLocalMicrosoftWindowsLock
  • WindowsWebCache in C:UsersDefaultAppDataLocalMicrosoftWindows

For each user account on the computer

You must be completely logged out before you can delete a hidden file or folder. If applicable, make sure the user’s profile is fully unloaded.

  • User(affectedUserFolder)AppDataLocalMicrosoftWindowsWebCacheLock.dat
  • AppDataLocalMicrosoftWindowsWebCache in C:Users(affectedUserFold).

You need to repeat this process for each affected user account on the computer in order to remove the files and folders from that location. Replace the (affected user folder) location with a valid user profile folder name.

Windows Intune client data is collected using this package as well as Microsoft Support One Data Collector (ODC).

As a result of a locked copy of another user’s cache database in the default user profile, performance issues related to event ID 454 can occur.

A new user’s default user profile is copied to their new one when he or she logs on. Using the database causes applications to experience negative performance or report errors when the Windows shell and desktop start loading. The database cannot be properly initialized once it starts loading.
