Nothing because it seems that I run two programs that are imcompatable.
Uses resources but does not seem necessary for anything

Ugh. Process starts seemingly randomly and often takes up 95-99% CPU. Trying to figure out how to solve the problem.
  John Richardson  
uses up cpu time
It runs itself periodically without asking, and creates a 99%+ memory leak the slows every on your computer to a crawl. no answer from HP (it started when I installed a new printer) so I don't know exactly what it does, but my networked all-in-one printer works fine without it. It appears to be a tool to send info to HP behind the scenes without asking you.  
uses all my resources and kills my laptop.
Can lead to IE not working after a PC wakes up from standby - deleting the folder solves the problem. / Der Prozess kann dazu führen, dass ein PC der aus dem Standby aufwacht, nicht mehr mit dem IE ins Internet kann (Process blockiert Handle WininetProxyRegistryMutex). Sobald er gelöscht wurde, startet IE wieder.

It is a high CPU hog that will automatic start after your computer comes out of the sleep mode. On Windows Vista it will pull 50% of available cpu. You then have to bring up Task Master and end the process.

Usless Process which only slows down your computer. Kill this Process(Thread). Some sort of usless software which sends information to HP and is bad programmed. Look like this application has lots of memory leaks.
Probably came with multipass printer
  Clarence Jones  
rename or delete it and you are fine
  Björn Spielvogel  
slowed my comp. to a crawl
It comes with HP Printer, suddenly it cunsumes up to 99% of cpu time or at least 50% if you hav a dual core.
  Peter Enis   (further information)
Takes up 50% of cpu resouces. Killing it gave me back my cpu and had no negative effects.

Best practices for resolving hprblog issues

A clean and tidy computer is the key requirement for avoiding problems with hprblog. 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.
