There are a number of variables that could be involved in various
combinations, but with no more info than you provide it's impossible to tell
which may be involved in your case. You make no mention of which version of
the program, which version of Windows, what size documents, detail about
their content, the system you're running it on or anything else that might
help someone point you in the right direction.

In general, though, programs don't simply wear out (slow down) with age.
Their behavior is dictated by the hardware on which they operate, and that
*does* deteriorate and /or get outdistanced over time. When did you last
defragment your hard drive? How much RAM do you have in your system? What
has changed about your computer configuration & software that might
contribute to Word not being able to work as fast as it once did - keeping
in mind that the OS is really what's responsible for swapping the windows.
