I read that the allocation type flag of MEM_WRITE_WATCH was 0x200000 (Track
writes to memory) and that if it is not supported, then ZwAllocateVirtualMemory
fails with status STATUS_NOT_SUPPORTED (seems quite a difference to what it is
written at the time).

There are quite a few cases of NtallocateVirtualMemory through other dlls than
CsVisual. Do you have an idea which ones would be affected by the virtual
memory if one had to adapt the references to MEM_WRITE_WATCH?

Quote: The flag MEM_WRITE_WATCH is only valid in Windows 2000 (reference about
NT/200). If the system does not support write watching and this flag is
specified, ZwAllocateVirtualMemory fails with status STATUS_NOT_SUPPORTED.
