- A new header that precisely documents the packet structure and protocols used for communication between SMSS and CSRSS has been added. The definitions match NT5.2.
- All required registry configuration parsing functions have been implemented in the new SMSS.
- Initialization of many internal data structures have been implemented for the new SMSS, ensuring it will present a properly configured and set up system when it takes over from the old SMSS.
- The new SMSS is now responsible for the initial system configuration, including setting up the environment, pagefile, and registry.
- The new SMSS is able to detect clean versus unclean boot/shutdown.
- The new SMSS can now launch 'native' applications.
- SmpSaveRegistryValue now properly deals with empty lists and correctly compares strings for equality.

- Loading of MENUEX resources has been fixed.
- The memory manager allocates a full 64KB memory block and returns it to the requesting code instead of merely aligning it to a 64KB boundary and returning a block of memory sized to the original request. A hack has been added so that even though the full 64KB allocation still occurs, the allocating code is only informed about the block of memory that matches its requested size.
- The memory manager now correctly deals with file access rights when mapping sections.
- MmFindGapBottomUp and MmFindGapTopDown have been reimplemented to properly create memory areas in the right places.
- MI_REAL_SYSTEM_RANGE_START has been defined to be the canonical system space base address and MmSystemRangeStart switched to a broken value to match behavior on Windows for 32bit mode. MmSystemRangeStart has the correct value for 64bit mode.
- A variety of page table initialization functions have been improved.
- MiRosTakeOverPebTebRanges has been renamed to MiRosTakeOverSharedUserPage and changed to only take over shared memory. Previous implementation did not even take over PEB/TEB memory correctly.

- Pool tag tracking has been implemented for both small and big allocations. Expansion is not yet supported.
- Memory allocation failures are now handled more correctly, with support for various debug and caller flags instead of simply returning NULL.
- Counters for paged and nonpaged pool have been implemented.
- The memory system is now VAD-based instead of using memory areas.
- Page fault handling has been considerably improved to handle a variety of situations and conditions.
