I have an additional problem beyond the one that I reported before. Not only has my system task bar disappeared again, in spite of removing that upgrade, but one of my most important pieces of software has become nonfunctional. I'm disabled after a stroke, and I have been successfully working with Dragon dictation software since. Although my typing ability has been coming back, I still rely on dictation every day, and I'm sorry, but Google speech doesn't work well enough for me.
You can see that I'm typing these days, but it's difficult and time-consuming for me. In addition, Dragon dictation is a function that is turned on and off with an icon in the system task bar. I also control several other functions that I use daily that way, such as turning my screen saver app on and off through a system task bar icon or turning on an app that allows me to hotkey Spanish letters.
All of these things are now nonfunctional. As a disabled person, Microsoft has done violence against me, today. What's wrong with you people? Have you no shame?
