    For Windows 11 home PC support, live chat with a Microsoft agent is available through either the Get Help app or the Microsoft Support website.

    1. Open Start, search for Get Help, and open the app.
    2. Describe the issue, for example: Windows 11 class not registered.
    3. Continue through the guided steps.
    4. If available for the case, choose Chat with a support representative or Request a callback.

    Alternative path:

    1. Go to the Microsoft Support contact page.
    2. Type Contact in the search box.
    3. Select Get help, then Contact Support or sign in to contact support.
    4. Choose the product and issue category.
    5. Select Chat with a support representative or Request a callback.

    If the issue is related to Windows Update on Windows 11, these Microsoft support paths are also available:

    • Use the Get Help app in Windows.
    • Use the Feedback Hub app to report the problem.
    • Use Microsoft Support for direct help with a home PC.

    Thanks!

    It appears there are several issues affecting various Windows apps. This Search-related symptom is usually linked to a corrupted user profile. Check if these problems also occur with a new user account.

    1. Go to System Settings (CTRL + I) > Select ''Accounts'' > 'Family and other users'' > ''Add another person to this PC'.
    2. On the Accounts screen, choose the option ''I don’t have that person’s login information' > Then select ''Add a user without a Microsoft account''.
    3. Click on the newly created user > Click "Change account type" > Under Account Type, change the option "Default User" to "Administrator" > Click "OK".
    4. Enter the username, and password (optional, leave blank if you do not want to put password) > Click ''Next'.
    5. Press the shortcut CTRL + ALT + DEL (DELETE) > Select ''Exit'' option > On the Login screen, choose the new user created.
    6. See if the problem will occur with this new user.

    Hi!

    Are you getting this error in a specific application? When opening File Explorer or starting Windows?

    Or does this error occur with anything you try to do?

    Please send me a screenshot and provide more details.
