    So any SLP key labelled "Microsoft" from this post ? >>> "Windows Server 2025 OEM SLP Keys" : https://forums.mydigitallife.net/threads/windows-server-2025-oem-slp-keys.88365

    Procedure has changed between previous versions of Windows Server ?

    I tried multiple possibilities in the VMX file but never saw any SLIC table showing up in RWeverything // See attached screenshot

    My VMX file contains this :
    • virtualHW.version = "21" >>>>> So let's assume I need the EFI20-64.ROM modded ROM file
    • firmware = "efi" >>>>> Entry was already present in the VMX file
    • efi64.filename = "EFI20-64.ROM" >>>>> I have added this line to get ESXi to load the necessary ROM file
    Any idea ?
    I'm pretty sure this is the reason why I'm not getting the SLIC table and/or the activation successful in Windows Server 2025

    I just noticed:

    efi64.filename = "EFI20-64.ROM"

    it should be

    efi20-64.filename = "EFI20-64.ROM"

    Hello and MANY thanks !
    Surely a careless mistake from me ... sorry for that.
    + I went to read the instructions (PDF file) again and found out that I just misread.

    Hello, I would like to know if it's possible to install my old recovery CDs from an HP Pavilion DV6-3022EK running Windows 7 Home Premium on VMware. If so, what is the procedure for adding information such as the version, model, serial number, etc. to VMware? Thank you in advance.
