Weird problem with wife's computer. In the last 3-4 weeks she would click an icon to start a W11 app from the taskbar and two occurrences of that app would start, like 2 Chromes, or 2 Thunderbird. Matters became worse during Excel spreadsheet when she was unable to copy-paste because she couldn't highlight words to copy and then right-click. How about more issues? Using the mouse to select numbers on the Calculator app would perform a different number.
Well, one would think this was a mouse (USB Wireless) problem. It wasn't! Now this is strange. After checking all settings against my same computer brand computer and finding them all the same on the same W11 Windows level, I moved Device Manager to examine the Mouse Hardware settings. Bingo! Mine ONLY had the USB Mouse Driver present. If I recall, I had problems over a year before with my Touchpad not functioning properly, and checked the driver for the SINGLE device, USB HID, I had. On her computer she had TWO mouse devices: USB HID and I2C HID. BOTH were using the same driver from Microsoft. Could it be that BOTH were functioning on the same action performed by my wife? And colliding? Well, it appears that was. I deleted the I2C HID entry to make it configured like my PC and the issues went away!
So, what really caused this collision/conflict? I could guess that it was a Microsoft update. Seems it started the same time my computer started to get a BSOD randomly dur to an update, that when backed off disappeared -- specifically KB5055523 on 24H2 Build or KB5055528 on my 23H2 Build. Backing that off fixed the problem. This went on on the special once per month security updates day (I think 2nd week in a month). I paused updates for 4 weeks and am on it again now -- hopefully fixed!
Getting back to the issues of this article, this time period was also when her PC mouse got "sick". Could it also have caused her problem? If so, it still isn't fixed today. Except for my change to delete the I2C HID. However, I2C was rebuilt (installed) next cold boot!
Thus, now I kept the 2 HID entries, but DISABLED the I2C one. Note: my Older Lenovo only installed the USB Hid, whereas, the newer (Wife's) Lenovo installed both a USB and I2C entry under Device Manager, Mic. Only the new Lenovo caused the problem and only in last 4-5 weeks. Now we are again in test mode. BOTH Hid are present , but only the USB Hid is enabled and working so far.
Scratch that. Now I switched mouse devices between wife and mine. I just hit her problem on MY Lenovo now. So, it appears it is the mouse or related to her mouse. In addition to switching the devices, I had also changed her Mouse Settings to make the Single click faster and the Double Click slower. No more incidents on her's PC with my mouse. However, I just changed the settings the same on my PC with her mouse and will see if it is setting related only. If not, time for new mouse I guess. I want to mention that an additional problem we have is single clicking and nothing happening. Specifically, I clicked the START Icon in taskbar and no menu came up. My wife reported that similar things on hers where a single click had to be done more than once.
Still, a bigger problem when all this started that only happened on my PC was a BSOD due to a MSFT Update. Which could be related. See here
SOLUTION:
Mouse itself. It acted the same on another PC. Needed to get a new mouse.
