renew9x does work, but it shows the winipcfg windows, which is not what you want.
The last one i did (renew9x2), doesn't show the windows, and it only works on win9x, not tested under win95 thou.
For win2k/XP you'll have to use the one you already have (renewhide.zip)
As for the log file, i don't know how how it works, you'll have to check it out, and if it happens to append, just delete the winipcfg.out file after 6 months.
