You were on the right track, spapakons. I tried reinstalling the original Windows 7 drivers and the USB mouse began tracking. However, the Synaptics touch pad would not disable. I tried editing the registry files in the prescribed manner which has worked in the past. However, this time, editing either the "Local" or "Machine" software registries for the touchpad did not disable the touchpad. My USB mouse is a microsoft wireless Intelli-mouse. In WIndows 7, when the wired transceiver sensed the signal stregth from the mouse was significantly diminishing, you would receive an on screen warning to check the batteries. I never received that warning in Windows 10 and after I had loaded the old WIndows 7 driver the mouse was recognized and worked and then abruptly stopped. I turned the mouse over and, sure enough, the tracking laser was completely out.
As I installed the new batteries, I began to wonder if this may have been the source of the problem all along (though the transceiver should have been recognized I would think even if the mouse batteries were dead). So I deleted the Windows 7 driver and installed the manufacturer's updated Windows 10 driver. It changed nothing except that the USB mouse was again not recognized. Instaed of "uninstalling" the Windows 10 driver and manually reinstalling the original Windows 7 driver, I used the "roll back" feature and clicked the "restart" button once it appeared in the Device Manager. As my notebook restarted it wouldn't let me choose the OS in the first screen and automatically started to open the Windows 10 OS after the 30 second timer expired and that was the end. It repeatedly froze at the Date/Time screen and I was unable to reach or log into the Windows log-in screen.
Spent all day yesterday trying to get the software to repair the "disk errors" and that completely failed as usual. Thought the software had created a restore point, yet when I tried to run a "restore" once again (since this happened to me several times a few months ago) it responded by saying there were "no restore points" found. I finally had to bite the bullet this morning and start from scratch reloading my copy of Windows 7 Ultimate.
I received a notice while waiting for updates to be found and downloaded that Microsoft will end the free period for upgrading to Windows 10 on July 29. I'm not sure I care anymore. The one lesson I can say that I learned from this experience is that I will go back to my original treatment of Microsoft Updates and never again allow my settings to be automatically updated & installed. This has cost me dearly in lost and unreplacable files as I had limited space left on my hard drive when this unexpectedly happened. I was in the process of copying and transferring files from the earlier crashes when Windows 10 was unintentionally installed.
Hopefully, lessons learned will not be forgotten. Thanks for your assistance, spapakons. I will retrieve what files I can that have not been lost and then wipe the drives clean and repartition the entire thing strictly for use with WIndows 7. If and when I can purchase and build a new computer that uses a touch screen and can take advantage of the newer OS, I will purchase my own copy then. Perhaps, Apple will finally win me over after all these years with PC's.
Again, you have my thanks, spapakons.
Pressing the physical eject button on my optical drives tray locks up Windows 10. I have to force a shutdown with the power button. I was hoping to kill two birds with one stone. Laptop still locks up if I press the eject button but now f9 shuts off my track pad.
Go to manufacturer's support site and see for a utility called Quick Launcher or similar. This is the one controlling all the extra keys. Install that and you should be OK
To spapakons & alphanumeric:
Many thanks to you both for your suggestions. I greatly appreciate the help you have offered. It will probably be a few weeks before I can backup what's left to save on my hard drives as I sort through them to determine what is junk and what is relevant to me and to copy all of it onto a travel drive. Once completed, I will repartition the drives and save one area for my Windows 7 Ultimate OS & one for use with a Windows 10 OS. At that time I will refer back to both of your replies and work from there.
You may hear back from me then, but until such time, know that your assistance was & is greatly appreciated.
