It writes a log file in C:\Documents and Settings\All Users\Application Data\hpqLog, and this can get very BIG. Mine was 67 Mb before I noticed after using the Laptop for 3 years. You can delete the log file and it will just create an new one next time it runs.

Best practices for resolving pthosttr issues

A clean and tidy computer is the key requirement for avoiding problems with pthosttr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
