Al,
Thanks actually I did the google thing too. It's not that. This has happended on every computer I've ever put these drivers on except one. These drivers and spyware built into the software packages are the real issue. Bert and I researched this a while ago when I bought the first of two new AIO's as our old monster was slowly dying. There are one or two drivers or processes that load during the boot sequence that get hung up and won't finish doing their thing. So you have to go deep in the the system set up stuff and switch them usually from auto to manual.
I'm convinced these are the parts that are waiting for a return call from the mothership or want to make one, but because I do a custom install and don't install all their "printhead mileage" and auto tracking of supplies, and auto updates, this thing can't satisfy it's prime objective and so they get hung up by my trying to keep them out. Heck on their website where you can contact them or even bitch, one of the check buttons is for "Are you concerned about your privacy with HP?" They know they have a spying issue in their midst because they really are spying on their customers. This is a real HP issue that many have been dealing with for quite some time now... Both the software drivers hanging up, especially when trying to turn off the feedback programs as well as their spying on folks in general.
Anyway these processes that you have to change the settings on are not the svchost.exe that is actually getting hung up and the amount of CPU useage is different for each machine. And they are always perfect parts of 25%. Last night was 25%, another machine was 50%, while another once was 100%. So you change these settings on actually HP parts of the installed software and the svchost issues go away, they even have names that start with HP. Uninstall the stuff and the issue goes away no less. It's no virus. Ii don't think any virus would allow it's self to be uninstalled by a OEM's uninstall program do you?
I'm sorry but until they make a public admission and start fixing these issues, I think these may be some of the last HP products we will ever buy....
