Sometimes an .exe is just a wrapper for a Windows Installer package (.msi). Inside the .msi, there are tables that define the installation process.
Tools needed: Universal Extractor (UniExtract) or Lessmsi.
Steps:
Note: Modern installers often do not contain a standalone .inf file because they use the MSI database tables to manage driver installation instead of a text script.
Many hardware drivers are distributed as .exe wrappers (e.g., IntelDriver.exe).
You can extract the actual driver files (including .inf, .sys, .cat):
Once extracted, you will find the real .inf file that Windows needs for manual driver installation. how to convert exe to inf file
✅ This is the only true “conversion” possible — extracting the pre-existing .inf.
| Tool Name | Legitimate? | What it actually does | |-----------|-------------|------------------------| | Exe to Inf Converter (sketchy sites) | ❌ No | Usually malware or fake | | Driver Extraction Tools | ✅ Yes | Extract .inf from driver .exe | | Inf-Writer utilities | ✅ Yes | Help you write .inf files manually (not conversion) | | “Convert” as a service (online) | ❌ No | Usually a virus upload trap |
Verdict: No legitimate direct conversion exists. Any online “exe to inf converter” is dangerous.
Based on what the EXE changed, craft an INF. A minimal example:
[Version] Signature="$WINDOWS NT$"[DefaultInstall] CopyFiles = MyFileCopy AddReg = MyRegistryAdd Sometimes an
[MyFileCopy] program.dll,,,0x00000001 ; copy to system32
[MyRegistryAdd] HKLM,"Software\MyApp","Setting",0x00000000,"Value"
Silent/unattended installation

Convert installer to driver package
Create an INF to register files/COM components
Most often, the request comes from:
The Analogy: Think of an .exe as a pre-packaged meal ready to eat. An .inf is the recipe card. You cannot turn the meal back into a recipe card, but you can take the meal apart to see the ingredients.
