Are you talking about the Word program? It has disappeared?
You can try this to turn back the clock on the computer:
Restore does not erase your personal files and is reversible.
click all programs
click system tools
click system restore
check the box that says restore my computer to an earlier time, click next
select a bold date on the calendar, a date before the problem started, click next
follow through with the restore directions
restart the computer after it finishes
if the system restore does not work, select an even earlier bold date on the calendar and repeat the procedure
try this with at least four earlier dates before giving up and trying something else
To see if Microsoft word is still installed, Press the windows key+R and in the run command type winword.exe If word starts you will be able to recreate a shortcut to it from Program files. If it is just a word document that you have lost, go to Start / search for files and folders. In the box type *.doc Every word document it finds will be displayed. Make sure you check all of your computer C drive.
