We received an update from Hewlett Packard on our other computer (Compac) and downloaded it. What a mistake!!! The browser hardly moves and now I can't get any website to load, it comes up timed out! I did a virues scan and apparently it found adware *MultiDropper-DU* with the download.
updates some HP Sofware (eg. HP Printer)
I had something similar happen to me as Diane. I (ahem) upgraded to a newer HP driver for my OfficeJet, and now when I try to change the print Properties (e.g., change paper size or switch between B&W and color), the system hangs. If I do this when not connected to a LAN/WAN, I can access this with no problem. I think this HPWuSchd.exe is the culprit, or whatever is loading this file is. The HP tech was no help to me at all...he just sent me a link to show how to install a network printer (!!!).
This is a valid program but it is not required to run on startup.
constantly dicks the hard drive & network -- prevents laptop drive shutdown thereby hogging power. Apparently related to HP 4215 printer drivers. not required for function of printer. EXE file has some other name.

Required scheduler for HP printers to keep updates for best possible driver configurations
Right click the process and go to the root folder. Running "config.htm" will open a page with updating settings. Check never and be done with it.
installshield update service
Typical useless clutter
The HP printer drivers, particularly the update features, are incredibly annoying. They interrupt the user with pointless crashes and Windows 7 security/update requests and I suspect significantly slow boot and shutdown. Despite years of persistent crashes and nonsense, no useful updates from HP have come through. I'm removing it.
hpweschd.exe repeatedly caused blue screen crashes until I went to msconfig and eliminated it from the startup options. Trial and error in the startups helped me find this culprit.

Best practices for resolving HPWuSchd issues

A clean and tidy computer is the key requirement for avoiding problems with HPWuSchd. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
