Ok, i have found out that it is by api patching. Like I said before, and like Koko did, it just modifies the gettickcount and timegettime functions to make it seem like more time has passed than...

Maybe this is beating a dead horse, but does anyone know how it works/know anybody who would know how it works?

Thanks! Hooking the api seems interesting, if not daunting.
I still don't know if it hooks time functions or uses a completely different method...i dont see any additional drivers in the directory...

Good idea. I looked and discovered that it uses functions like SetSpeedTimes and SetAPIHook in its hook.dll, and in its INPROC module. Though i could disassemble it, it would not glean any...

Is it a crime to inquire how an application works? I have been trying to say all along that you can't change process speed through priority. I just want to know how it works, that's all.

That's true. You wont be able to identify what's causing it, but you WILL know it's there...

Can thread priority be fined tuned or is its concept the same as process priority, ie the 4 levels? EDIT: And yes, i am sure it works the way i want it to...that's really the reason why i was so...

Yes, i understand that part. But in speeder xp has fine tune values, anywhere from 50-20000. Priority only has a few levels, so speeder xp does it a different way. Does anyone know the way speeder xp...

Ah, but you forget a good keylogger would have rootkitted itself and otherwise be hidden completely from the user, which means you couldnt monitor it through normal means.

Thanks for the reply! I'm well aware of the fact that it does not really speed up the CPU, i'm just wondering how exactly it fools to application into running faster.
For all those interested,...

That's what i'm referring to. Though i know the cpu speed is controlled strictly by hardware, greg_dolley's post stated that it would be possible to artificially speed up an application. For an...

Thanks to everyone who replied. However, i still don't understand how to change the cpu speed using setpriorityclass. This only modifies the priority class...how do you finetune the cpu speed change?

The first program, speeder XP, uses 6 dlls:hook.dll,ntperf.dll,ntport.dll,Softwrap.dll,babout.dll,inproc.dll. None of these really stood out to me except hook.dll, but i don't think hooks could be...

This is a good idea; you could use a blank window and use postmessage to send hordes of useless keystrokes; the log would have the real keystrokes scattered between the useless gibberish.

At first i thought it was set process priority too. But what appears to be happening is that it is artificially speeding it up using some other means. This is because you can select the amount of...

Hello,

I have seen programs like "Speeder XP" and "Xelerator" that actually change the speed of a process. I'd like to know how they did this, because i have scoured the windows api and have found...

All right, its about a month later, I aced all of my midterms, haha, and i still can't solve this program. I can send an individual keypress, but i cannot make it stay down. If i send a KEYDOWN msg,...

Hi guys,
Yes, I am well aware that this topic is over 10 months old. However, I have some information that might revive it, as sending keypresses to an alternate application has always been a big...
