Files in mediaplayer on W7

I have some files listed on my windows media player library showing that are no longer on my hard drive. It will not let me delete them for some reason. Waht can I do to get rid of these? I right click, asksme if I want to delete when I click on delete, but nothing happens after that. Obviously the files cannot be accessed when the location no longer exists, any ideas?

 

Recent File List

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file1

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file2
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file3
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file4
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file5
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file6
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file7
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file8
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file9
...

you get the idea. ( too lazy to put it in a for loop and test it.

or just open regedit and remove all the fileX from that key.

 

Deleting the "SoftwareDistribution" Files

I noticed that "Depending on your HDD Space and you made sure your Updated on Windows 7" that you can delete all the Files "Going into Safe-Mode of course" but i saw a .Txt File that shows the Updates you've installed "That i deleted by mistake" but by deleting that File i saw the updates needed to be installed again but i knew weren't true.

So yeah what ya' think? Should this be a good idea? I saw that over 3GB worth of files!
