|"It's a modified windows xp."|
I note your System Properties screen/window is not the standard one for XP. The Windows logo looks like the one for Vista.
Did it have SP3 updates built into it?
If it didn't , did you install Microsoft's SP3 updates?
In my standard System Properties screen, and on my standard System Information screen, it shows SP3, and in System Properties it shows version 2002, for a computer that has XP MCE 2005 (has SP2 updates built in) that was updated with the SP3 updates.
