Would you mind sharing your modified files?

In addition, how can this work in win 8.1 ?

Sorry, the modified files are too big, the igdumdim32.dll and igumdim64.dll totaly around 180MB so I couldn't upload them here. And if you choose different version of drivers, you need modify it again, they are not universal to use. This is why I didn't publish a complete drivers here. But I think follow my quick step you can easliy got it to work.

 

If you want driver's working on win 8.1 or other windows version, you just need add the device description line into the other section of system, for example, win8.1 you need add this line 

 

%iKBLULTGT2%        = iSKLD_w81, PCI\VEN_8086&DEV_5917

 

into the section [IntelGfx.NTamd64.6.3]

I have your answer, see my post here:

Hi there,

 

    This is the quick step, if you don't want read more:

 

   1. download intel graphics driver 21.20.16.4839

   2. Do the inf hack, looks into the Graphics directory, find the file igdlh64.inf, modify it. Add this line into windows 7 install section [IntelGfx.NTamd64.6.1]

             %iKBLULTGT2%        = iSKLD_w7, PCI\VEN_8086&DEV_5917

   3. Find the file igdumdim32.dll, edit it by a hex editor, like winhex or ultraedit. Search this binary string in it:

             83 F8 13 75 43 F7 42 04 00 00 00 02

       modify the following two bytes into

             90 90

   4. Find the file igdumdim64.dll, edit it by a hex editor, like winhex or ultraedit. Search this binary string in it:

             01 76 17 83 F9 13 75 44 F7 42 04 00 00 00 02

       modify the following two bytes into

             90 90

   5. install the driver, restart.

   6. install/reinstall the discrete video card driver, not recommend a newest one. I use nvidia 397.64 driver on my MX150.

   7. enjoy it with full fucntion works.

 

Start from here:

 

     As you know Intel didn't support graphics drivers for 7th and 8th CPU on windows 7, I do lots of research on web found some inf hack to resolve it like this:

 

    https://www.youtube.com/watch?v=J6nPLoRtipA

 

    This way looks  work, but not perfect, I found when I playback video, player always crash on my UHD 620 (Embedded in I7 8550U) , whatever I used.

 

   And someone said replace some dll file will let playback work normal, but 3D function couldn't work, like this guy:

 

    https://www.techinferno.com/index.php?/forums/topic/12141-intel-core-i7-8th-gen-with-windows-7-intel-uhd-graphics-620-driver-dell-inspiron-5770/

 

 

    I try all methods in the post found the same issue, so I try to dig into this problem, and finally I hack the driver binary file(DLL file) successfully.

 

    I must say this is not easy, you need some hacking background to understand how it work.

 

    First things, choose a right driver version. I do a lot testing work to test different version.I try to merge some of them but all of them couldn't work stable enough. Finally I did some research the about the  display drivers difference between winows 7 and windows 10.

    Basically, the display drivers support windows 7 must follow WDDM  1.1, but on windows 10 it support WDDM 2.0+. This means you must choose a version which support WDDM 1.1 and it support 6th or 7th CPU at the same time. Another words, your driver version must support both windows 7, and then  can support graphics like HD 620 on windows 10. 

    Drivers can match this demands isn't too much, the newest you can found officially is version 15.45.23.4860 (21.20.16.4860):

 

    https://downloadcenter.intel.com/download/27360/Graphics-Intel-Graphics-Driver-for-Windows-15-45-

 

    This version is OK, but I didn't use it, because I found drivers in same series 21.20.16.xxx, which is 4839 is listing on the windows update catalog directory by Microsoft. This means it should be more stable, you can download it from here:

 

    https://www.station-drivers.com/index.php?option=com_remository&Itemid=352&func=fileinfo&id=3256&lang=en

 

    The windows catalog version is here:

 

    https://www.catalog.update.microsoft.com/Search.aspx?q=21.20.16.4839

 

    Then, the inf hack work, this is most easy part. You can learn how to do it on youtube from my first link. Here's some notice, the UHD 620's device ID is PCI\VEN_8086&DEV_5917, add the line in windows 7 section which should be like the following part. Here I use a new marco iKBLULTGT2R , and this can let you name your device, but not use HD 620's name,

 

;=====================================================================
;    Windows 7 Install - DT Only
;=====================================================================
[IntelGfx.NTamd64.6.1]
; SKL HW
%iSKLULTGT1%     = iSKLD_w7, PCI\VEN_8086&DEV_1906
%iSKLULTGT2%     = iSKLD_w7, PCI\VEN_8086&DEV_1916

...
%iSKLWSGT4%    = iSKLD_w7, PCI\VEN_8086&DEV_193D
%iKBLULTGT2R%        = iSKLD_w7, PCI\VEN_8086&DEV_5917

 

      And add some lack parts for UHD 620, this is not really important thing, if you don't do it's OK. Add these lines follow the 5916 section:

     And don't forget add the new display name at the end of this file:

 

; KBL 
iKBLULTGT1     =   "Intel(R) HD Graphics 610" 
iKBLULTGT2     =   "Intel(R) HD Graphics 620" 
iKBLULTGT2R     =   "Intel(R) UHD Graphics 620" 
iKBLULTGT2F    =   "Intel(R) HD Graphics 620" 
iKBLULTGT3E15  =   "Intel(R) Iris(TM) Plus Graphics 640" 
iKBLULTGT3E28  =   "Intel(R) Iris(TM) Plus Graphics 650" 
iKBLULXGT2     =   "Intel(R) HD Graphics 615" 
iKBLDTGT1      =   "Intel(R) HD Graphics 610" 

 

    OK, now save the file and run setup to install the drivers, it should be work. After restart, you will found the Aero came back again. And run dxdiag to check if the 3D function can work, it should work. Here you even can play some 3D game now. But the player crash couldn't stop. And the video tab of intel configure panel will crash too.

 

   Most tutorial  on web will end here, but my hacking is just begin. Here I must claim someone wants try to merge file to let this work, I don't think this will work. Because the different WDDM support in diffferent system, if one driver only support in windows 10 it couldn't be run on the windows 7.

   I tried merge the windows 10 driver into windows 7, and resolved tons of DLL missed and function redirect, modify tons of improt table of DLL, The drivers can be loaded, but it won't work. Just like you install a defalut VGA driver, no 3D function will work correctly.

 

   I started from the player crash, it reported that it crash in igdumdim32.dll @0x59c4EA0C,  the igdumdim32.dll and igdumdim64.dll is the Intel's user space graphics drivers' core file, the Intel's graphics has a small kernel part called miniports, it only open the tunnel between userspace application and the hardware, the real working part is in the DLL, like 3D function, video acceleration  and Direct draw. Use a debuger like ollydbg to debug it I found it's a function do some  setting work:

    This function is setting some thing according a flag which read from call on @59C4E95F, and the following part is a complex branch to select correct arguments for the function call @59C4EB0F. I tried some trace route and found we need let  branch @59C4E9C2 goes false, so here we make it to nop like this:

 

59C4E9B1    83F8 16         cmp     eax, 16
59C4E9B4    74 17           je      short 59C4E9CD                   ; igdumdim.59C4E9CD
59C4E9B6    83F8 13         cmp     eax, 13
59C4E9B9    75 43           jnz     short 59C4E9FE                   ; igdumdim.59C4E9FE
59C4E9BB    F742 04 0000000>test    dword ptr ds:[edx+4], 2000000
59C4E9C2    90              nop
59C4E9C3    90              nop
59C4E9C4    C746 18 AC05655>mov     dword ptr ds:[esi+18], 5E6505AC
59C4E9CB    EB 31           jmp     short 59C4E9FE                   ; igdumdim.59C4E9FE
59C4E9CD    8B42 04         mov     eax, dword ptr ds:[edx+4]
59C4E9D0    A9 00004000     test    eax, 400000
59C4E9D5    74 09           je      short 59C4E9E0                   ; igdumdim.59C4E9E0

 

    OK, the most important part comes, translate the RVA into file address, and modify it. Sounds really hard isn't it? Good news is there is a more easy way, and this is the signature about this fix:

 

    83 F8 13 75 43 F7 42 04 00 00 00 02

 

    Search this hex string in the file, modify the following two bytes into "90 90"

     We need the do same thing for file igdumdim64.dll, but because this is 64bit dll, so the signature is different:

 

   01 76 17 83 F9 13 75 44 F7 42 04 00 00 00 02

 

    The modify should like this

 

002d56f0h: 73 09 48 8D 05 1F AD A7 04 EB 6D 0F BA E1 1D 73 ; s.H?..雖.横.s

     OK after modify the two file, replace it into the windows directory, if your windows is 64 bit, put igdumdim64.dll into windows\system32, and  igdumdim32.dll into windows\sysWow64. This must be done under the safe mode, restart windows and press F8 before windows startup, goes into safe mode to replace it.

 

    After reboot, you will get all things work.

 

   PS: In my system the nvidia's video card cause some problem, it will let system hang sometime, I highly recommand to reinstall the nvidia's drivers after install the Intel's drivers. and choose a lower version, but not the newest version. I have UHD 620 and MX 150 in my system, and after I reinstall the 397.64 nvidia drivers the problem gone away and the laptop works like a charm.
