SymStore

This repository contains header files with structures, unions, enums, global variables and functions names from the symbol files for the core Windows operating system components, and tools to help get and compare the files.

Note: Because there is no correct way to get information about nested unnamed structures and unions, some structures and unions are not the exact copy of the original.

How to install tools

Symbols Explorer

1. Download Symbols Explorer.
2. Copy SymExp.exe to a Debugging Tools for Windows folder. For example: C:\Program Files (x86)\Windows Kits\10\Debuggers\x64.

Tools

1. Copy SymStore folder from the Tools folder to "C:\Users\%UserName%\Documents\WindowsPowerShell\Modules".
2. Copy Diff.bat from the Tools folder to "C:\Users\%UserName%\AppData\Roaming\Microsoft\Windows\SendTo".
3. Install Visual Studio Editor.

Copy-Item -Path SymStore -Destination "C:\Users\$env:UserName\Documents\WindowsPowerShell\Modules" -Recurse
Copy-Item -Path Diff.bat -Destination "C:\Users\$env:UserName\AppData\Roaming\Microsoft\Windows\SendTo"

How to compare header files

1. Select two header files.
2. Right click on the first file and then select "Send To->Diff" from the context menu.

How to download symbol and image files

Get-Symbols -FilePath "C:\SymStore\Manifest.txt" -Destination "C:\SymStore\Symbols"

Note: Unfortunately, some symbol and image files are missing from the Microsoft symbol server and some image files are stored with original name and SymChk from Debugging Tools for Windows is not able to download those image files.

How to store image files by version

Add-ImageFile -FilePath "C:\SymStore\Symbols\ntoskrnl.exe\a45bf00aa6f000\ntoskrnl.exe" -Destination "C:\SymStore\Binaries"
Add-ImageFiles -Path "C:\SymStore\Symbols" -Destination "C:\SymStore\Binaries" -Recurse
Add-ImageFiles -Path "C:\SymStore\Symbols" -Destination "C:\SymStore\Binaries" -Include *.exe -Recurse
Add-ImageFiles -Path "C:\SymStore\Symbols" -Destination "C:\SymStore\Binaries" -Include hal*.dll -Recurse

How to get header files

New-HeaderFile -FilePath "C:\SymStore\Binaries\ntoskrnl.exe\10.0.17763.316\x64\ntoskrnl.exe" -Destination "C:\SymStore\Include\ntoskrnl.exe"
New-HeaderFiles -Path "C:\SymStore\Binaries" -Destination "C:\SymStore\Include\ntoskrnl.exe" -Include nt*.exe -Recurse
New-HeaderFiles -Path "C:\SymStore\Binaries" -Destination "C:\SymStore\Include\ntdll.dll" -Include ntdll.dll -Recurse
New-HeaderFiles -Path "C:\SymStore\Binaries" -Destination "C:\SymStore\Include\hal.dll" -Include hal*.dll -Recurse

¹ Header files are not present because there are no symbol files on the Microsoft symbol server.
² Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files.
³ 64-bit version of ntoskrnl.exe contains implementation of hal.dll.
