perflib_perfdata_*.dat ??

[jerry]

Each time I start Windows XP, a .dat file is created in the
c:\windows\temp folder with the name perflib_perfdata_ and a different
number and letter combination. I can delete all of the files except the
last one created. 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.

Does anyone know what these files do and what program creates them?

TIA, jerry

These files are created by System Monitor, the performance monitoring tool
with XP. There's a good thread on them here:

Good luck,

These files are 'orphaned files' usually generated when your pc is shutdown
improperly or a particular process is aborted. It can be any process it is
not specific to one service or process. Obviously something is not shutting
down correctly but as to what is anyone's guess. I certainly haven't got any
instances of the file on my pc - well not that I can see at the time of
writing this post anyway. The only thing I can point you to is :

Although it doesn't give much information and from reading it there is no
indication of a possible solution.
