Hi Cedric EYRAUD,

The issue you are experiencing with the Taskbar and Start Menu search stems from how standard user profiles interact with Windows Appx package registration during the login process. Specifically, the search interface relies heavily on the MicrosoftWindows.Client.CBS_cw5n1h2txyewy package, which acts as the core framework for the Windows Experience Host. Because your corporate environment uses roaming profiles configured to delete the local profile cache at sign-out, the operating system is forced to unpack and re-register this specific package from scratch every time you log back in.

The recent March update introduced underlying modifications to the file and registry permissions required for this specific package deployment. When your standard user account attempts to write the necessary files to the C:\Users[Username]\AppData\Local\Packages directory and populate the required registry keys under HKEY_CURRENT_USER\Software\Classes, the system halts the operation due to insufficient privileges. This leaves the search components unregistered and completely unresponsive. When an administrator logs in, their elevated security token allows the package deployment to complete successfully, which is exactly why the search functions perfectly for those specific accounts.

Attempting to force a bypass of these local administrator requirements is not possible without violating your network's security protocols. This issue requires intervention from your IT department to resolve centrally. Your administrators will need to either temporarily adjust the Group Policy that clears the roaming profile cache to bypass the daily re-registration requirement, or deploy a subsequent Microsoft cumulative update that officially corrects these Appx deployment permission structures for standard user contexts.
