Thanks for reading... I found it
http://www.microsoft.com/hwdev/driver/sfp/wfp.asp

but i realy want know if disabling this will improve the system performace.

As per the guide;

Disabling WFP
For the more performance hungry users out there disabling WFP is seen as a pretty good way of freeing up some resources, though has obvious drawbacks as stability may be concerned. Still if disabling it appeals to you it’s not too hard to do, though personally I’d recommend against it.

Perhaps most critically is that since the release of Windows 2000 Service Pack 2 & Windows XP the procedure for disabling WFP has changed considerably, most sites you may have visited on this subject still show the old Windows 2000 pre-Service Pack 1 method which no longer has any effect. Given that I don’t recommend doing this at all, should you require instructions check Axcel216’s Guide (http://members.aol.com/axcel216/2k1.htm) out which covers disabling it in Windows 2000 Service Pack 2 & Windows XP – scroll down to the DISABLE FILE PROTECTION section.

Performance wise there shouldn't be too noticeable a performance difference, few percent maybe at best.

thanks Thomas!
