What steps should I take if igdumd64.dll is absent?

1. Transfer igdumd64.dll Manually

The simplest method to recover the missing igdumd64.dll file is by obtaining it from another computer that runs the same version and architecture (either 32-bit or 64-bit) of Windows. The igdumd64.dll file is typically located in: C:\Windows\System32

To proceed, connect a USB drive to another computer, navigate to the System32 folder, copy the DLL to the USB drive, and then transfer it to the affected system. Place igdumd64.dll in the same directory, and restart your computer.

2. Reinstall the Graphics Driver
