my ssd is recognized as internal sata drive, and i did reinstall sata drivers.
i did boot a duplicate drive as internal drive and refreshed it - it removed all aps i had installed but did make it no longer a 'windows to go' system.
thanks
i did use 'mini tool drive copy' to make a duplicate of my ssd, and then tried to start windows using the (usb)duplicate drive.
but i never changed the ssd - maybe using duplicate drive triggered some change of my internal ssd.
