Personally, I'd first use Task Manager and enable the "command line" column (I'm sure PE has it, too). There, it is possible to see the command line the process has been started with. I'm also using a tool named "Process Lasso Pro" that additionally shows the parent a process has been launched from. The command line for the batch file (.cmd or .bat) shoulöd reveal its path where it is located. Further clues: The file is either a .cmd or a .bat file, plus it includes a call to the Windows "TIMEOUT.exe" utility and the "AvastAntivirusWorldwideE.exe".
Thanks.... Task Manager is the very first thing I tried. There is no .cmd, no .bat, no Timeout.exe and no Avast...exe As I understand a lot less about computers, than probably everyone else here, I am probably also a lot less surprised that this, for one reason or another, cannot be solved. But I did learn a lot again. Right now, I want to try everything suggested, but I suppose, sooner or later I will have to re-install Win7 again. What is the best tool to (again) wipe the SSD that you can recommend, before the clean install?
That is what I usually do. And still..... many files and folders from "Fujitsu" remained installed...
Not sure how it's possible that you still have folders after deleting all partitions since a folder can't exist without a partition. So I assume it's a fujitsu SSD? If there's not a fujisu utility to erase the drive you can do it with gparted or parted magic booted from a usb flash drive.
It is at this point and after reading previous posts which show contradiction with our "normal" experience with drives erasure, managing partitions, reinstalling Windows, etc, when I wonder whether the OP is doing something wrong or many things wrong. Honestly.
Yes, like not actually deleting all partitions during install. If folders are surviving then all partitions aren't being deleted. I guess that could possibly be because of a bad drive but I don't know. The only way to know for sure would be to boot from a usb flash with windows install media, PE, parted magic, gparted, or linux; then delete partitions. Then reboot with the usb drive and see if the partitions are really gone. If the partitions aren't really being deleted it would be the first time I've heard of it.
Strange. If a cmd is open, there must be a cmd.exe process running. In case of Task Manager, you need to show processes of all users, of course.
I always backup my drivers with double driver once I have everything working right. Then after a clean install just update drivers in device manager and point to the double driver backup folder. Works perfect every time on any version of windows.
