All that that is is a copyright statement for the C Runtime Library. 
CACHE386.EXE was probably developed with Microsoft C 6.0.  You'll find
copyright statements by Microsoft, Borland, Watcom, and other compiler vendors 
in many applications and utilities.  That doesn't mean that Microsoft,
Borland, Watcom, /et al./ developed those applications, or own any rights to
the application code in them.  Those are the copyright statements for the
runtime library code, written and owned by Microsoft, Borland, Watcom, /et
al./, that is linked into the applications.

Ironically, the licence provisions for use of the Runtime Libraries in
applications developed using the commercial C and C++ compilers from
Microsoft, Borland, Watcom, /et al./ are actually *less* restrictive on what
applications could be linked to them than the original GNU Library licence.  
The compiler vendors generally bend over backwards to point out that they
don't own the code of the applications that are linked to their runtime
libraries.  (Although Microsoft does put in restrictive terms that limit what
*kind* of applications can be developed using its compiler.)

The existence of a copyright declaration for the C Runtime Library for
Microsoft C version 6.0 embedded within the executables does *not* imply that
Microsoft owns any rights to the application code in CACHE386.EXE, BOOTSH.EXE, 
PREPACL.EXE, or any of the other files.

For those interested in such trivia, the OS/2 Command Line Utilities are
members of a very select group of application programs that do *not* contain a 
runtime library copyright statement from Microsoft, Borland, Watcom, MetaWare, 
or any other compiler vendor:
