Provided MS word has not been un-installed.
You may be missing just the icons.
You can use the built in search and look for MSWORD.exe
If memory serves me this is the file name of the executable.
Have you tried simply opening another word document from explorer?
If MS Word has not been un-installed the program should start right up.
Everything Displays both files and directories.
Pleasure to work with and highly recommend especially for lost files.
Excellent alternate to MS word is
OpenOffice Best of no cost and includes a full office package. And yes converts from and too MS office file formats.
Hope this helps
