Angels have the Phone Box
Sorry for taking so long to respond to this, but I don't have FAST START enabled anymore (LOL)
I get the explorer error at every shutdown, if I left-click Start>Power>Shutdown. When I right-click Start>Shutdown or sign out, I do not get the error. HOWEVER, if I left-click Start>Power>Shutdown, I get the error again. It doesn't go away for me.
2. I don't have this.
3. I don't use a mail client.
4. I don't have this recurring message problem
and I'll add #5:
I have a setting for the Synaptics trackpad to be disabled when a mouse is plugged in. On each boot, it disables after sign-in, and gives me a sound + message that swipes in from the right. That swiping message used to be at the top of the screen, but now it appears to be at the bottom behind my taskbar and is not visible at all.
