How to Install Windows 7 on Computer with Less than 512MB RAM
InformationThis is a process by we can install Windows 7 on computers with less than 512 MB of memory.
This is only for 32-bit version of Windows 7 because it is nearly impossible to run 64-bit version of the OS in a computer with less than 512 ram.
Although you can install Windows 7 Ultimate edition, but I recommend to install Home Premium, Home Basic, or Starter editions. Use at least 256MB ram.
WarningThings you need:
1) Windows 7 32bit ISO
2) A HEX editor. I prefer Free Hex Editor Neo.
3) UltraISO or powerISO.
Lets get started:
1) mount the ISO and copy the file "winsetup.dll" from the sources folder to any of your local drive.
2) Now open winsetup.dll with the help of Free Hex Editor Neo.
3) Under 0008e528 on the left side, find 77 07 3D 78 01 string as in the screenshot below.
4) Replace 77 07 3D 78 01 with E9 04 00 00 00 and save the file.
5) Now open the windows 7 32bit iso with UltraISO or PowerISO. Open sources folder and replace the winsetup.dll with the file you just modified. And delete ei.cfg file to unlock all windows 7 SKU. And then save the ISO. Burn it and Install.
