Thank you Thorsson! I believe I understand what you're telling me. Since I have no previous clone/backup of my system anywhere...
I assume it's useless to do it now as it will only save a fubar'd version of my system. I uninstalled the new update after the flickering screen of death and other problems, and I THOUGHT it was back to it's original state.... but not so!
It worked great for a few hours after the uninstall, but seems remnants of the new update are in there somewhere and wreaking havoc once again. I'm waiting for locusts to start emerging from my machine!
I wish you LUCK on your bravery by reinstalling W-10 tomorrow. Let us know how it goes! I'm tempted to do it myself, but TBH, I'm in no mood to go through what I did when I first got the update. Perhaps we could all roll back to MS-DOS and start from there! Have to keep a bit of a sense of humor or I'll go batsh*t crazy with all this.
I looked at your link and for sure it says BACK UP before installing in more than once place. It says: "If you have personal data and files that you want to save, back them up to an external hard drive, USB thumb drive, SD card, or cloud location (such
as OneDrive) before you begin to reinstall Windows 10." I lost faith in MS at this point, so I would not use their OneDrive. Another program where they will say 'oopsy' when your files disappear. How comforting.
Appreciate your reply and insight. TY again!
