Window 11 v24H2 Build 26085.1
I had found this tool , in this forum earlier, presented by well known VIP Member. I used this tool, please find attached herewith, to upgrade from Win 11 22H2 to 22H3 on my unsupported pc, for Win 11 to run.
Extract zip folder. Drag and drop downloaded iso Win 11_23H2_English_x64 from official website of Microsoft, on to Get_Win11.cmd, keeping internet on.
After a few minutes , a new iso is ready to install / to upgrade .
To upgrade from within working current os version of 22H2, run AllowUnsupportedUpgrades.cmd as administrator. This file will be seen after mounting the image created by Win-11-Download-Prep-Tool-Main. New iso will result in OS Build 22631.2428, version 23H2, after installation/Upgrade.
Please find the zip file and other images required to verify the result, herewith.
Thanks everyone for reading this thread.

To fix error of unsupported pc while installing Windows 11 23H2 using iso created by above mentioned tool, using manually created bootable usb:-

If we create bootable usb for Windows 11 23H2 manually (without using third party software like Rufus) in the following way:-
Run CMD as administrator
C:\Windows\system32>Diskpart
DISKPART>List Disk
DISKPART>Select Disk #
DISKPART>clean
DISKPART>convert mbr
DISKPART>create partition primary size=2048
DISKPART>create partition primary
DISKPART>select partition 1
DISKPART>format fs=fat32 quick label="BOOT"
DISKPART>assign letter=x
DISKPART>active
DISKPART>select partition 2
DISKPART>format fs=ntfs quick label="INSTALL"
DISKPART>assign letter=y
DISKPART>exit
Mount newly created modified iso of Windows 11 23H2.
Copy all files from mounted iso except ,sources folder , to Fat 32 partition.
Manually create "sources "folder here.
Copy all files from mounted iso to NTFS partition. Cut boot.wim from sources folder and paste it into sources folder which we manually created in Fat32 partition.
Now boot from this usb , but we get well known error of unsupported pc while installing. Installation stops showing the error.
To fix this error , press shift F10 at this point to bring command prompt.
Now we have
X:\sources>notepad
Click>File>open RegUpdates.reg.
After locating this registry fie right click on it to select Merge.
Registry gets modified and then click back arrow and click accept again to proceed without any error to install Windows 11 23H2.
Please find RegUpdates.reg file attached herewith.
Thanks everyone.
