  VCache is the virtual device driver (.VXD) that manages the use of
some memory -- memory not already in use for application code or data
-- to hold blocks recently read from or written to disk.  There's a
reasonably good chance that, as a program runs, many of its requests
to read information from disk can in fact be satisfied from this
memory instead of waiting for the disk hardware.

  The question typically arises in one of two contexts:

1.  In Windows 3.11, .VxDs were loaded individually.  In Win95, many
of them are bound into IO.SYS, and load automatically at boot time.
If you start up with a boot log, you'll see a couple of failed
attempts to start VCACHE.VXD individually, because it was already
successfully installed.

2.  You can specify the minimum and maximum amounts of memory that
VCACHE should use, in WIN.INI.
