### Bug description

Overlay icons like the share icon (marked green) are missing


in Windows Explorer if Windows account is logged in already.
Virtual files are activated.

This bug report is a byproduct of the comment in that bug https://github.com/nextcloud/desktop/issues/5301#issuecomment-1768009683 and behaves in the same way.
I suppose the solution will be analogous.

### Steps to reproduce

1. Log into a first Windows user account with Nextcloud Client installed and check that overlay icons are shown.
2. Log into a second Windows user account and check the Nextcloud folder. No overlay icons (like the share icon) are shown.

### Expected behavior

Overlay icons should show for every user account on the Windows system, even if another account is logged in already.
