Does Windows 7 Pro have all the security around the bootscreen that Ultimate has? Can the OSXML be converted into XML ? Where did Thiamin get his info? hacking? John

I just made my own compressor / decompressor for BOOTMGR; LZNT1 Tools (compression in bootmgr and ntfs) - reboot.pro and downloadable from; LZNT1_Tools.zip It uses winapi and works perfect both ways. Windows 8 up until 6.2.7955.0 are verified working. After that compression method changed, but I believe support for it is found in the same winapi (on that particular OS though). Sources included in download.

@thaimin
Do you plan on releasing your sources too? And have you looked at the latest Windows 8 version?

Hi All! Apparently I stopped receiving emails about new posts...

@joakim - Funny thing about the compression. I just decided to write up LZNT1, LZX, Xpress (Lz), and Xpress Huffman compressors and decompressors and release the source (see Coder for Life - Microsoft Compression Formats for a summary of research I did).

The LZNT1 one is almost exactly what I have in bmzip, which provides that exact same compression ratio as RtlCompressBuffer but adds a single extra null byte as required by Windows 7 bootmgr - so no improvement from Winapi. BTW, my implementation is at least 25x as fast at compression but half as fast at decompression (working on that).

The Windows 8 bootmgr uses Xpress Huffman. I have a decompressor for this already, and am working on a compressor. Windows 8 does indeed include a Xpress compressor with RtlCompressBuffer however the decompressor always fails in v6.2.8102.0 x86 (even if I use RtlCompressBuffer then RtlDecompressBuffer).


Current status of compressors:
LZNT1: 50x faster than Winapi with identical compression ratio
LZX: No compressor yet
Xpress (LZ): No compressor yet
Xpress Huffman: Much slower than Winapi but comparable compression ratio (sometimes better, sometimes worse)

Current status of decompressors:
LZNT1: Half as fast as Winapi
LZX: Works, but no Winapi to test against
Xpress (LZ): Works almost as fast as Winapi
Xpress Huffman: Much slower than Winapi


I am thinking of releasing the source for the next version of my entire program. However it would be difficult for others to look at since it is written in C, C++, C++/CLR, C# and asm.

Sounds very good. I'll have another look at the latest Windows 8 version and try something, hopefully this afternoon.

Do you happen to know the values for COMPRESSION_FORMAT_XPRESS and COMPRESSION_FORMAT_XPRESS_HUFF?

@joakim - Yes I do! Found through IDA (although it ended up being obvious...).

#define COMPRESSION_FORMAT_XPRESS 0x0003
#define COMPRESSION_FORMAT_XPRESS_HUFF 0x0004

Both accept COMPRESSION_ENGINE_STANDARD or COMPRESSION_ENGINE_MAXIMUM as well (haven't tried COMPRESSION_ENGINE_HIBER since the MSDN says that doesn't work).

You need to use RtlDecompressBufferEx() with XPRESS_HUFF (and maybe XPRESS, I am now using the Ex version always). The workspace buffer I use is the maximum of both values for both engines given by RtlGetCompressionWorkSpaceSize.

OK, but I'm stuck now and will continue tomorrow night. FYI, I just noticed you can also use lznt1 on the newest Windows 8 if using this stub; LZNT1_big_stub.zip

Hmm, the 0x0003 seems mentioned here; http://undocumented.ntinternals.net/...essBuffer.html although with a different name.
