# Who knows what's goin' on?

Who in this group, the whole PF for that matter, knows what's goin' on during a Windows XP startup? What does it take to have a real good understanding of everything that's goin' on while Windows XP starts up?

I have "Autoruns" and even that is a bit complex.

Can or is anyone willing to summarize for me in a short paragraph, the boot-up process for Windows XP?

You know, I see what those chopper dudes see in stripping down a motorcycle to it's barest bones. That would work for me with my PC.

Thank you Ranger. That however only describes the boot-strap and what the operating system first does when it gets loaded. Mainly I was interested in the procedure (exact sequence) in which all the varous application programs startup in windows. Like, all the ones in Windows Task Manager.

Well you go Ranger! I think you got the dibs in here dude. Other people in here too. Don't wish to offend anyone. That's a good start for me. I just need to sit down and spend some time with it.

Thanks.

You may also check out Windbg, I say Win debug but some say windbag. Not at me, thats what they call windbg. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tools/tools/windbg_debugger.asp [Broken]

The other thing to do is get whats called a "Checked Build" of your XP as opposed to the free build

What I though was interesting to read is that during the loading of the operating system kernel, NToskrnl.exe, the "HAL" files are loaded . . . hummm . . . interesting. Does that mean HAL is in everybody's PC?

That just looks like a debugger Brad. I've used the debugger with MicroSoft Visual C++ a ton debugging applications I've written.

Wanna' tell me what a checked build is and how to get it?

HAL(Hardware Abstraction Layer) - This is the code that produces the interface between the hardware and any software using it; for example, a graphics adapter, and an API.
Definition from www.futuremark.com/community/hardwarevocabulary/[/URL]

Well according to that definition, it sure seems so. On my linux system, I can recall seeding a "HAL daemon" load at boot time.

Well, I'd like to take this one step further if I can:

You know how when you use a debugger, you can "step through" all the calls to the various functions?

It would be nice to have that ability to "step through" the boot process for XP. I realize that's the "cart before the horse" (what's gonna' run the debugger"). But it doesn't have to be real. It could just be a simulator that you run which "simulates" the boot process but you could "step-through" it just like you would an application in a debugger.

Any body have any ideas?

Oh yea, the reason for having such is to learn about the boot process in detail. That to me gives you more control on your PC. Frankly, I do not like using a PC in which all kinds of stuf is runnin' and I don't know what it is. Also don't want to slow down my PC.
