By default media player will show all
recent played files. You can disable this as sometimes
you do not wish other people to know what you have been
viewing or listening to.
First, before editing your registry
remember to always back it up first, just incase you do
something wrong. The registry when modified is an
instant change and cannot be undone.
BACK UP REGISTRY: So to open the
registry editor click on "START",
"RUN", then type "REGEDIT" (No
speech marks). The registry editor will now open, click
on "FILE" then "EXPORT". From the
save window that appear type in a file name (ie
regback.reg), now click on "SAVE". Your
registry has now been backed up.

TO DISABLE RECENT FILES: Now on the left
hand panel click on "HKEY_CURRENT_USER" ,
"Software", "Microsoft", "MediaPlayer",
then "Preferences" Next search for
"AddToMRU" in the right hand panel. If it is
not present then simply create it by doing the
following:
Right click on "Explorer"
select "NEW" then left click on "BINARY
VALUE". Name the new string value in right hand
panel as "AddToMRU".
Now to set the value, double click on
the string value and set it's value to "01"
for enabled or "00" for disabled.
