781. You don't want a dying mouse in your house

Tonight my wife said the mouse was broken, it didn't display a pointer on screen. Well, it had power. The touchpad was also not functioning and the system was locked up. So, power off/on should clean it up. It didn't. Here are some of the problems existing:
1. Right-click from anywhere should bring context menu up promptly. It took about 10-20 seconds to see menu
2. Went to Windows Updates to see what went on. It said "No updates have been installed". Yeah, right. This is a know problem starting in August 2017.
3. Regedit would not allow expansion of entries. Now we're talking major problems!
4. System Restore to checkpoint yesterday FAILED. 0x80070091 error. Also a know problem! Hello, Microsoft! You can look these up. This supposedly has a solution that requires a simple rename of WindiwApps folder.

After screwing around with all this, the recovery failed, but this time the restart it required somehow cleaned up the other problems. Go figure! Except, the Windows Updates still indicate No Updates.

Below are some website hits for problems mentioned:

Followup: I am going to contribute most of the problems to the mouse battery being about 99% depleted! Although never experiencing problems like this, I would guess the weak battery, hence potential right-click failures or delays, propagated problems with mouse driver which caused performance problems throughout. However, the Restore problem remains Microsoft know problem that some people claim the temporary solution is renaming WindowsApps folder prior to restore

780. Logitech Mouse does its own thing

Here's a weird problem: You perform actions with mouse, i.e., move the pointer to some hypertext and your system erratically performs as if the mouse does a left-click on its owns. For example, I have a dictionary on my system and to look up a word I simply double-click the left mouse. Well, I started to see definitions appear without doing so! Another example, I do a click on something, like a file, and it acts as though I double-click. Now the worse scenario so far was I ordered something, thankfully not anything of value (only a free book from Kelloggs rewards which should have taken one of my 2 credits) and it double-clicked and ordered the same book twice. You never see it happen its so fast. 

Anyway, my first inclination was to power off, reset the mouse. I chose right. I removed the battery from the mouse and after 1 minute reinstalled it. It cleared up everything. Gotta love guessing right. I may have achieved the same result by disabling mouse and restarting. But, removing a battery was so much easier. It seemed like a hardware error, but most likely the power off/on sequence reinitialized it.
