Setting a Copy-File Flag to Support PnP Stop
A new copy-file flag is required for display drivers that are written to the Windows Display Driver Model (WDDM) in order to properly support Plug and Play (PnP) stop (that is, driver upgrades that don't require a system restart).
The following example shows the new copy-file flag that is added to just the copy-file section for user-mode display drivers and not display miniport drivers:
; ; File sections ; [r200.Miniport] r200.sys [r200.Display] r200umd.dll,,,0x00004000 ; COPYFLG_IN_USE_TRY_RENAME r200umd2.dll,,,0x00004000 ; COPYFLG_IN_USE_TRY_RENAME
