    Than all for replies... have tried different versions of bootmgfw.efi but all except one results in a black screen.
    The graphics card is a Radeon Sapphire se.
    All drivers load and work except graphics and wifi.

    Trivia : Did you Know That Sapphire Radeon Cards of AMD (Up To 6950 XT) Are The Best Candidates To Run MacOS ?

    Tip : For Those Desperate To Run Windows 7 On Sapphire Cards,

    You Can Use MacOS As A Bridge For Running Windows 7 On Sapphire Cards... (Two Bridges To Be Specifically Clear !)

    it can be done through CSM
    the patch was mainly done for pure EFI mobos that has no legacy support whatsoever
    the patch mostly do the same thing as what CSM does
    it momentarily enables bootefix64 to be renamed from the thing.. cant recall
    then it uses a built in win 8.1/10 kernel trick sort of
    idk exactly but for the 70% of the time, this is how it works
    sadly at the end of the day, uefi is not the death of win7 but the eternal tls 1.0 curse
    which many many let it behind
    and while underdeveloped, his elder brother, win 8.1, has some +

    Sure. a quick check through ms docs lead me to this

    reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v Enabled /t REG_DWORD /d 1 /f
    reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v DisabledByDefault /t REG_DWORD /d 0 /f
    reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp" /v DefaultSecureProtocols /t REG_DWORD /d 2560 /f
    reg add "HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp" /v DefaultSecureProtocols /t REG_DWORD /d 2560 /f


    run these in cmd as administrator ;)

    to conclude my post
    download a freeware tool called IIS Crypto CLI
    this will further let you know if any measure are worth following
