for window users: (to get rid of genre in the browse list and itunes store arrows)
iTunes 8 - Hide Genre in browser/iTunes store links on Windows
iTunes 8 was released today (well yesterday, but who?s counting?) with new features like Genius sidebar/playlists, HD TV show and a new visualiser. (wow

)
However, they have removed two of the UI options I used, namely hiding the genre in the browser and links to the iTunes store. I don?t find browsing by genre useful; only a handful of my songs have genre tags. I?ve never thought to myself ?Self, I really wish I could browse for a specific genre.? Add to that you are limited add one genre to a particular song and for me at least they are completely pointless (tags, on the other hand, would be awesome

)
Searching Google, there are solutions for both of these issues, but they are Mac only :hmm: . However, I?ve found the solution for Windows (which works for me anyway).
1. Ensure iTunes is not open. Browse to the iTunes Application Data folder (C:\Documents and Settings\User\Application Data\Apple Computer\iTunes on XP, C:\Users\User\AppData\Roaming\Apple Computer\iTunes on Vista, substituting the drive letter and the user profile name where necessary.
2. Backup and open the iTunesPrefs.xml with a half decent text editor (ie not Notepad, my personal preference is Notepad++)
3. Find the User Preferences key, and below the <dict> tag insert:
<key>show-genre-when-browsing</key>
<data>
AA==
</data>
to disable the genre column in the browser, and:
<key>show-store-arrow-links</key>
<data>
AA==
</data>
to disable the links to the store.
4. Start iTunes.
To get back either the genre column or the store links, just remove the respective key.
