Hi Mike,
The default location for templates is
C:\Documents and Settings\<your name>\Application Data\Microsoft\Templates
You can find this in the Tools > Options > File Locations dialog in Word.
The reinstallation of Windows may have changed the <your name> part, so Word
is now looking in a different branch of Documents and Settings. If so, all
you need is to move the templates to the new location.
In Windows Explorer, you'll have to go to Tools > Folder Options > View and
turn on display of hidden folders and files, because the Application Data
folder is hidden.
