This says that there is nothing wrong with Word itself or the cursor but
some outside influence. In Safe Mode, Word is running in its default install
mode bypassing all customisations, macros, templates, printer drivers and
add-ins of any kind.
I initially suspected the printer driver because it is one thing in common
that all three apps you report having this problem: they all need a
compatible printer driver.
I am in two minds as to the problem though, so let's start by eliminating
the printer driver by going to the Printer applet and selecting Add a New
Printer. Choose the Generic Text driver from the Windows standard printers,
install it setting as the Windows default. See if the cursor is back.
If that fails, then my next suspect is a corrupted Word DataKey in the
registry, but I am not sure why Excel & PPt would be affected though they do
all share some common settings.
From Start, Run, type in
regedit
and press enter. Navigate tot he Data key and delete it. Word will
automatically recreate it when it is next started.
