HP representatives can claim their software doesn't cause problems but I'm here to tell you they do. my HP that I am using as we speak that I have had for almost 10 years had problems every time I have tried to let HP software update do it's thing to my computer and right afterwards my computer would start to lock up and I would have to RE-wipe the HDD. I say re-wipe because I would only do let HP software updates run or I would run them myself. So, fresh copy of factory original software then updates from MS and HP and I have a computer that won't travel the web let alone play solitaire.

I have several different HP printers on several different PC's; No problems, no impacts, but not necessary. Run it monthly at a Low Priority.

I'm using a non HP notebook. I guess I got this process after installing the drivers for a HP printer.
It is just a hp printer service
It is harmless. You can change the settings so that it connects once a week, month, or even longer. The only information it sends is OS, language, location and device id's. Suzanne, you had a virus by your own admission. Don't blame HP update for that!

The HP Windows Updates Scheduler task is automatically installed as part of the driver and software package of some HP printers and peripherals, periodically checking for updated drivers for these devices. In practice, drivers are not updated very frequently, and so it is not necessary to keep these sorts of update checker programs running constantly, though some people find them a worthwhile convenience. If you want a detailed security rating about your hpwuschd2.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager. Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!
