Let alone the installer size, does anyone else out there have kind of mediocre performance with iTunes in Windows Vista? I've had a number of times where it just seems to come up black, or respond slowly, or syncing just slows my PC to a crawl. Is this just a local issue for me, or is iTunes truly broken for many other 'normal,' if you will, people out there?
Also, as a sidenote, why does an update need to be near 60 MB anyway? We don't have to download 26 MB for any Windows Media Player updates, or a multi-gigabyte download for Windows Updates.
[Updated 10-Sep-2010. I have completely updated and republished this post to cover iTunes 10. See The unofficial guide to installing iTunes 10 without bloatware.]
[Updated 27-Sep-2009: Apple has now released iTunes 9. I have updated this post accordingly.]
[Updated 3-Oct 11:30AM PDT: After I did the original research for this piece, Apple released iTunes 8.0.1. I have been unable to find a set of release notes or a changelog for this versions, but I have updated filenames referenced in this post to reflect the new version number.]
How do you supersize a simple music manager? Ask Apple. The Windows version of iTunes 8, released earlier this month and quickly patched after it caused an outbreak of blue-screen crashes, is a 64MB download. (For the sake of comparison, Windows Media Player 11 for Windows XP is just over 24 MB.) The full iTunes 8 installation takes up nearly 200MB of space on a Windows PC.
As it turns out, the iTunes installer has been bulking up for the past year or two. Don’t be fooled by the filename: iTunes801Setup.exe, the most recent version as of this writing, includes much more than the iTunes client. Without any disclosure and without your consent, the iTunes 8 setup program installs kernel-mode drivers, multiple system services, and at least one add-in. It takes a supersize helping of chutzpah to create an ad that criticizes Windows for its “bloat” and then deliver an upgrade with as much unnecessary junk as this one. Update: The iTunes 9 installer is even larger and includes one more component, as I document below.
The last time I wrote about this, several commenters defended Apple by insisting that every component in that full install was necessary, and that trying to carve away any of those bits will degrade Apple’s awesome end-to-end experience. I’ve looked at the iTunes installer on multiple Windows machines and am convinced that those Apple defenders are wrong. If you’re like most people, you don’t need any of that additional junk. In this post, I’ll explain how you can figure out which parts of the package you need, and then show you how to wrestle control of iTunes back.
For starters, let’s look at everything that’s in the iTunes Windows installer, with an explanation of what it’s used for and how you can decide whether you need it:
- QuickTime is Apple’s multimedia framework, a collection of codecs, plugins, DLLs, and several players designed to help you play back digital media files in most popular formats. The big selling point is support for the QuickTime movie (.mov) format, via the standalone player or an embedded ActiveX control.
- iTunes is Apple’s all-purpose media player/device sync application. If you own an iPod, this is the only officially supported way to interact with it, although third-party alternatives are available. iTunes also provides access to the iTunes store, and if you own an iPhone you must use iTunes to activate it, update its firmware, and sync its content with your PC.
- Bonjour is Apple’s implementation of the open-source Zeroconf, a multicast DNS responder used to discover services on a local area network. It’s installed by default with the iTunes download and also installed silently with some Adobe products, a decision that “freaked out” some Adobe customers. Adding unauthorized peer-to-peer services on a corporate network is a distinct no-no, as a number of customers have told Apple on their support forums. (The response? Crickets.) If you want to share iTunes libraries over a network or use Apple TV, you need Bonjour. If you have a printer attached to an AirPort device, you should use Bonjour. However, if you simply want to play media files and sync your iTunes library with your iPod, you don’t need Bonjour. (And Photoshop users can safely remove it as well unless they have a Version Cue server on their network.)
- Apple Mobile Device Support is the synchronization framework for the iPhone and iPod Touch family of “mobile devices.” This package is not necessary if you have any other member of the iPod family, including the Classic, Mini, Nano, or Shuffle, which sync just fine using just the basic iTunes app.
- MobileMe is the support software that enables synchronization of email and contacts and calendar items with Apple’s MobileMe service (previously .Mac). It is included with the iTunes installer to update existing installations, but is no longer installed as part of a default new setup.
- Apple Software Update is a utility that checks for new versions of Apple software installed on your PC. It also pushes new Windows-compatible Apple software programs. Understanding how this utility works is crucial; it can and will install software you have explicitly rejected if you don’t monitor its actions carefully.
- Apple Application Support is new in iTunes 9. As best as I can tell, it is a framework for managing applications on the iPhone, iPod Touch, and (presumably) future devices. It is a required component for both iTunes and QuickTime.
