i have an MSI GE73 Raider RGB 8RE and win10pro
i can modify text in search box as well as cut and paste. i just discovered that the right click does not bring up a cut/copy/paste menu on mine, but it will cut/copy/paste using the standard keyboard shortcuts (ctrl+C [copy], ctrl+Y [undo], ctrl+X [cut], ctrl+v [paste]). i am used to using the keyboard to cut and paste, so it is not that big of a deal for me anyways.
