    Inge,

    Awesome graphic!

    That really cleared it up. Did you make any progress on creating a utility to update the SLIC in the HyperV exe?

    Thanks.

    It's working as expected :eek:

    Just install W7 as "Generation 1" guest and install a valid license :D

    Is it? Hope it helps ;)

    The tool is working so far and does always a good job, but the Gen2 implementation is missing :(

    But Gen 2 is only for Win8.x / Server 2012 R2, so no issue there then...

    Inge,

    You do have a utility that adds the SLIC in the exe for Gen1?

    you're right, no issue here but it's worth to mention it ;)

    Yes, but it inserts only the missing MSDM table and puts the well known SLP1 strings in their
    valid range. If I remember (the source is written some years ago), the SLIC/RSDT/XSDT tables
    are already present. You just need to overwrite the SLIC table and adjust the RSDT/XSDT pointers.


    MSDM table structure:

    Code:
    Signature[4]
    Length[4]
    Revision[1]
    Checksum[1]
    OEM ID[6]
    OEM  Table ID[8]
    OEM Revision[4]
    Creator ID[4]
    Creator Revision[4]
    Version[4]
    Reserved[4]
    Data Type[4]
    Data Reserved[4]
    Data Length[4]
    Data (KEY)[29]

    Usually my tool installs the exe, but this should also work:

    • Shutdown (don't save) all your guests and open a command prompt (admin privileges required)


    Then type:

    Code:
    01.) net stop vmms
    02.) icacls c:\windows\system32\vmwp.exe /save C:\windows\system32\vmwp.acl
    03.) takeown /f c:\windows\system32\vmwp.exe
    04.) icacls c:\windows\system32\vmwp.exe /grant:r %username%:F
    05.) rename c:\windows\system32\vmwp.exe vmwp.old
    06.) copy c:\PathToYourModded.exe c:\windows\system32\vmwp.exe
    07.) icacls c:\windows\system32\vmwp.exe /setowner "NT Service\TrustedInstaller" /c
    08.) icacls c:\windows\system32\ /restore c:\windows\system32\vmwp.acl
    09.) del c:\windows\system32\vmwp.acl
    10.) net start vmms
    

    You can also put these commands in a batch file and execute it with admin privileges...


    Close the command window and restart the VM's - done!


    Please let me know if it works...

    Thanks! I will take a test tonight(+8:00). I am sure I had not shutdown the VMs when I replace the vmwp file.

    If you don't restart them, how should they read the new bios?

    I had restarted some VMs(not all) later. And the restarted VMs need to active. The others is OK.

    I normally change the VMWP.exe by hand, but tried your DOS cmd's for fun.
    They work perfectly and are a lot quicker ;)

    You need to uncheck the downloader of Datafilehost; Inge's posted checksum is correct.
