User Comments

hphmon05.exe is a process relating to the Hewlett Packard software HP PHotosmart, and provides easy access to flash card reading functions. This program is non-essential process to the running of the system, but should not be terminated unless suspected to be causing problems.
it's causing a lot of page faults and I/O other.
This file allows the user, through HP Photosmart software/program, to access/use the computers SanDisk (SD/SDisk; ) card reader (usually reads any size SanDisk memory card [to allow user to display/view digital camera photos, transfer digital images from camera to computer, etc.). This is one file (of however many that make up HP's PhotoSmart application/program) that should be kept on the computer after (correctly) being installed, remain unmoved (to avoid becoming lost, corrupted, or deleted accidentally or otherwise), and to have continuous availability for future use.
I know that it's running all of the time when I'm not using this program. It makes me nervous,
I know nothing about it, but its making my computer go super slow, I have to end process everytime i boot up my computer
When looked under "Task Manager" it shows up as an application with an increasing amount of Memory Usage, and eventually leads to the 'Virtual Memory Too Low" message, even when no other user-active program is being run concurrently. It is easy enough to kill it just by using "End Process", but the question remains how did it show up in the first place and why does it behave the way it does.
It has a bug in it where it drains system RAM. I'd boot up and ctrl-alt-del and you can watch it's RAM usage increase by the second. This causes eventual error messages saying virtual mem too low. Essentially, it renders the computer unusable after some time, where you can't even ctrl-alt-del to end it. I had to hold down the power button.
HP printers are good but then again when you install them, it loads a lot of crap at startup consuming resources.
About this file - the sluggish like all of the HP software. Next time DO NOT buy HP
It only uses 960k in my Task Manager, check for some updates for your product(s)
This process is continually loading advpack.dll over and over even when successful. This is what is causing the slow down noticed by some people. It's a harmless process, but another shoddy Hewlett Packard program.
Hp Printers are good quality from the hardware but the amount of system resources software which the hardware uses is uncalled for. I have uninstalled all irrelevant HP software now since the above file was generating 4 times the number of page faults as explorer.exe. VERDICT: Good Printers/Bad Software
It has been causing a lot of page faults. I think my system has it because my HP printer has a multi-card reader built in.
if not turned off opens door for others to hack ur pc unless u have better than windows firewall!!! shutting it off wont harm anything i shut it off right when i installed printer!!
I researched it, and have experimented with it.. none except CCleaner ( which allows easy disabling and re-enabling of startup items
Is responsible for advertising some "privacy suite" software randomly on my computer, is reason enough for me to disable it right there.
I get a hphmon.exe application failed to initialise message popup and its annoying

Removing it from Windows/System 32 improved PC Doctor's performance rating from serious to good.

Best practices for resolving hphmon05 issues

A clean and tidy computer is the key requirement for avoiding problems with hphmon05. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the hphmon05.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
