Those of you interested in the Windows kernel-mode internals are probably familiar with the syscall tables I maintain on my blog: the 32-bit and 64-bit listings of Windows system calls with their respective IDs in all major versions of the OS, available here (and are also linked to in the left menu):
- Windows Core (NT) System Calls: 32-bit and 64-bit.
- Windows Graphical (Win32k) System Calls: 32-bit and 64-bit.
After a few years of inactivity in this area, I’ve found some time to update and thoroughly refresh the tables. The changelog is as follows:
- Added information from Windows Server 2003 (R2, R2 SP2), Windows Server 2008 (R2, R2 SP1), Windows Server 2012 (R2) and Windows 10 (1507, 1511, 1607).
- Clarified some versions of Windows, resulting in removing non-existent Windows Server 2008 SP1 (32-bit), Windows XP SP0 (64-bit), Windows Server 2003 SP1 (64-bit), Windows Server 2008 SP1 (64-bit).
- Removed empty columns with missing information from the win32k 32-bit table.
- Performed a major clean up of the lists, resolving all syscall handler collisions and renaming invalid symbols (e.g. “FsRtlSyncVolumes”) stemming from compiler optimizations to their correct form. From now on, all system calls are represented by their real names starting with “Nt”.
- Unified the layout of NT and win32k tables.
- Added more granular information to the win32k 64-bit table (accounting for all service packs and major releases).
I hope the tables keep proving useful for Windows researchers interested in those interfaces. :-) And of course, all comments, suggestions and bug reports are highly appreciated!
