so as windows xp source code have been publicly leaked, i downloaded that 7z archive.

the architecture of windows xp is way to complex, tons of files and folders exist.

i started simple, by looking for pre-loaded windows programs like notepad, calc .. etc., what really shocked me is even such simple programs have tons of lines of code, like wow!

anyhow moving further, and digging deeper; i figured out that kernel32 and ntdll (and many other core libraries) are compiled/assembled from 10+ files.

i thought i would find ntdll.c and ntdll.h, but no i was wrong, and tracing back all those files is a big overhead.

good stuff is, there are few documentations of the architecture itself.

have any of you messed around?

Why waste your talent in vain?

XP "It's retired, it's still obsolete."

Tons of lines of codes compared to Windows 10?

Just because the OS itself is deprecated, does not mean the source code that was used in it is. Microsoft reuses a lot of code between versions of Windows, so a lot of what was in XP is still used in 10.

There is plenty of interesting and useful information in the leaks.

Mostly just looked around at some things I've messed with for bypasses/anti-cheats etc. but haven't really done any major digging into any of it.

I agree. I quoted what the vast majority of people say about XP.

Hey I still use it in VMware. In fact, XP is way faster (than Win 10) when you want to make a ThinApp portable program.

I heard the same words about CDs, who buys audio CDs today when the vast majority listen to music only in digital format?

im not sure who am i talk to but fyi, mircosoft dont create their windows versions from scratch.

most of system code is same since windows nt 4.0, most core libraries haven not change much between major updates and version releases; so what makes you think its old or deprecated code?

i can bet that 60% of windows 10 code is based on nt4. nt5 and nt6, there are few leaked files from windows 10 source and they are identical to the code seen in win2000...

"I've messed with for bypasses/anti-cheats"
i am mainly interested in ntdll, PEB and TEB.
especially in PEB and TEB as they contain some leaked ring0 addresses.

Windows Internals 4th Edition
