"a correction was made,you obviously missed."
Yes and no. Yes I didn't go and look to see how ostensibly simple it was. No I went through the installation and I knew what uninstalling would be.
It was late where I am, around 10:30 pm. I went to bed at 11:30 and the thing was still chugging along. When I got up in the morning and rebooted, there was another 40-minute wait. Now it's done and, hurrah, the screen is back to normal so the time was well employed. However, the endless search for INTEL ® ICH9 Family USB Universal Host Controller 293X, to my surprise, still goes on and on at startup. Now I have been able to find some suggestions elsewhere, e.g. http://social.technet.microsoft.com/Forums/en-US/itprovistahardware/thread/15ff094b-2992-4f99-96a7-947fc9ecdbce
, but what surprises me is that all these people are third parties trying to make money out of the fact that HP, INTEL and Microsoft can't make there computers work properly and that you can't tell them anything, only go into some forum where there are no answers available. As they say: Anyway...
Thanks again for the help.
