OK. Closed down Windows 10, went into the VMware settings, found that I had 4 processors and almost all the RAM allocated to VMware, so went back and changed this to 2 processors and the recommended RAM (2048 MB), leaving 14000 MB for the Mac. No improvement in opening times for things like MS Word.
Opened the Task Manager and found that it was running at 99% or 100% CPU most of the time.
