Each time I start winXP home edition, a file is created in the c:\windows\temp folder with the name perflib_perfdata_ and a different number and letter combination without the .dat extension but it is listed as a .dat file. All of the files created can be deleted except the last one created. I can delete it if I reboot to safe mode with command prompt and use the del command. When I reboot another file is created. I am not having a problem, but I haven't been able to discern which service or program creates the files and prevents them from being removed. I have searched the net and I think they are some type of network performance data files.
Does anyone know what these files do and what program creates them?
