A collection of combined Windows NT syscall tables covering ntoskrnl and win32k service tables across Windows versions from XP x64 through Windows 11 builds. It provides reference data (in C and browsable HTML) mapping syscall numbers for x86-64 Windows kernels.

Use cases

• look up syscall numbers for a specific Windows 10 or 11 build
• build a Windows kernel research or hooking tool that needs SSDT indexes
• resolve win32k syscall IDs when writing security research tooling
• compare syscall tables across Windows versions
• find the syscall number for an Nt function on Windows Server 2022

When to choose

• you need authoritative syscall number mappings for x86-64 Windows kernels
• you are doing kernel-mode security research, rootkit analysis, or EDR development on Windows
• you want precomputed tables instead of extracting them from ntoskrnl/win32k binaries yourself

When to avoid

• you need 32-bit (x86) syscall tables
• you target non-Windows operating systems
• you need a runtime syscall-resolution library rather than static reference tables
