Search Feature in remoteapp mode (no explorer.exe)

Currently, users cannot type into the Windows Search field in Explorer or standard Open/Select File dialogs when connected through TSPlus RemoteApp.

We confirmed that starting explorer.exe within the user's RemoteApp session immediately restores search functionality. However, this also launches the Windows taskbar/desktop shell, so it isn't a practical solution for RemoteApp deployments.

from my understanding and testing this issue exists on windows server 2022,

An easy way to reproduce this issue is by going to any windows 2022 server, killing the explorer.exe process for that user and then via the task manager opening notepad and using the “open” feature (ctrl+o) and finally typing into the “search” box.
