By default media player will show all
recent played file, url history and playlists. 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 DELETE RECENT FILES: Now on the left
hand panel click on "HKEY_CURRENT_USER" ,
"Software", "Microsoft", "MediaPlayer",
then "Player".
Next search in the left hand panel for :
RecentURLList - This shows website
streams, delete contents as necessary.
RecentFileList - This shows recent list
of files, delete contents as necessary.
TO DELETE ENTRIES FROM TOOLBAR: Now on
the left hand panel click on "HKEY_CURRENT_USER"
, "Software", "Microsoft", "MediaPlayer",
"Player" then "MediaLibrarySettings"
(or MRUList). Delete contents as necessary.
