Echoing the same problem. ctfmon only fixes keyboard, not task scheduler (or software protection) failure (UBPM.dll fault). Restarting explorer and removing Parallel Tools does not seem to have any impact.
Windows update (2017-08 Cumulative Update) was possible by running the Troubleshooter and fixing a database error. Did not fix the problems.
UBPM.dll fault is likely behind everything. AppCrash logs show:

Update: I did find one reference in a Windows forum that this might be related to a C++ Redistributable library, and I noted that my Visual C++ 2012 Redistributable was listed in the Apps as being installed in July 2017. Removing it had no effect. This problem is all over the Windows forums and may be completely unrelated to Parallels.
I have also tried removing my second monitor, operating in Windowed, full screen and Coherence mode.
