Windows 10 Taskbar Disabled

Shawn
After reading the caveats in the "Windows repair without losing anything" guidelines about conflicts that could mean nothing is saved, I'm afraid I "chickened out" a bit. The problem isn't serious enough to risk losing everything, especially as there is no certainty that it will fix the anomaly. It seems a pity that programs with a pedigree like Windows don't have the necessary tools to unravel these sort of problems, although that may result in a vast increase in support for live systems. Thanks very much for your assistance.

I "took the plunge" today. :)
I did a Macrium backup, followed by Windows Repair/Reinstall. I am pleased to say that it all went well, and so far the Task Bar has not misbehaved. I was hoping that my problems with Internet Explorer 11 might be related to the task bar issue, as they seemed to occur together. However even after the repair, my IE11 issues remain.
I will report back in a few days as to whether the task bar issue is solved, as of course the IE11 problem is not part of this thread.

I'm pleased to say that since I did the Windows repair you suggested, the Task bar has not given me any problems, and we can now mark this thread as solved. Thanks very much for your excellent support on this. :)
