Well, I finally solved the vermin mystery and to say I’m unhappy with myself is putting it mildly. I feel like an idiot for not solving it sooner but an even bigger idiot for not remembering what should have been a red flag of what broke it in the first place. It proves I’ve lost some of the edge I once had. Once upon a time I didn't forget stuff.
This was all done in bits and pieces over the last week.
Booted into a Linux live distro and scrolling worked fine.
Using my old m.2 to test with, I restored my last image of 21H2 made last November. Scrolling worked. At that time I used XMouse button control to control my mouse button actions and it had worked correctly for me for years.
I then restored the first image I made of 22H2 last December, scrolling still worked, but when I restored an image of 22H2 from January, it didn’t work. I was sick of dealing with it so restored the December image again and set about getting a year’s worth of Windows & apps updated, and tweaks for the last year reapplied. Once I did, I made an image which I restored to my new working m.2. OK, I’m back in business.
This morning I had to work on my husband’s computer. Under all the piles of crap he keeps on his desk was an 8 button ergonomic monstrosity given to me last Christmas that I absolutely hated, as did he. That’s when a light bulb finally came on.
I used that horrible mouse for one day in January. I had uninstalled XMouse and programmed that mouse from hell buttons using Logitech’s software. When I shucked the mouse, uninstalled the Logitech software, and went back to my old mouse, I reinstalled XMouse and restored my old XMouse profile. The 2 pieces of control software were never installed both at the same time….I thought…. because when I did a clean boot only XMouse showed up in startup folder.
Now at this point, any rational person would have left it alone since everything was finally working, but it was driving me nuts to know the WHY of what caused it and why setting scroll lock would make it work. I was on a quest and am not always sane when I am questing. I become obsessed.
I've worked most of the day trying to figure this out.. I re-installed the old m.2 again, restored the January image to it again, and set about searching. I found a lot of registry entries relating to Logitech as well as remnants in appdata and programdata, but not in program files, which indicates to me the software did not cleanly uninstall. I usually use Revo, but I must not have in this case or all this stuff would not have been left behind. Though I can't be certain I am assuming this to be the cause of my scroll problem. I'm telling myself that anyway so if you think differently, please don't tell me. Leave me to my delusions.
The only thing I know to be 100% true is this entire ordeal has whipped my butt.
