I updated my XP computer to Zune software 4.0 and it imediately took 100% of available CPU time. I thought the software must be loading my music library or maybe Smart DJ information, so I left. When I came back two hours later, it had loaded nothing! It was still using all available CPU. It would not play any media, go online, or even sign in. I had to use my computer for other tasks, and I did. Windows runs no more slowly with Zune software 4. I was running a word processor and a browser. After about 6 hours of work, there was no change. I tried reinstalling Zune, but that did nothing.
This system:
-an ancient beige box
-800 MHz Intell Pentium 3 CPU
-512 MB RAM
-128 MB NVIDIA GPU
Zune support was usless. They recommended the typical:
-uninstall Zune, restart computer, reinstall Zune, restart computer;
-uninstall Zune, restart computer, uninstall .NET framework, restart computer, reinstall .NET framework, restart computer, reinstall Zune, restart computer;
and so on! (I have to admit that I tried it, but of course it didn't work.)
I gave up after 4 hours and went to bed, leaving the computer on with Zune software running and screen/power saver disabled, hoping that Zune would finish processing whatever it is.
And now, 14 hours later, I'm actually listening to my MP3s on Windows Media Player! (Zune software has been running the entire time and is still using 100% of available CPU time.) Zune software 3.1 worked beautifully on my system, so I don't see any logical reason for Zune software 4 not to work.
Anyway, if anyone knows how to fix this, tell me!

Bug details:
What works:
- The GUI. Specifically, anything user interface-related that doesn't require internet. (Like browsing collection, now playing screen, menus)
What doesn't work:
- Any feature that uses internet. (Like Marketplace, login, usage rights)
- Video playback
What partly works:
- Local music playback. Specifically, the first time after software launch, a non-DRM song will play after about a minute of loading. Sometimes, I can jump to different locations in the song, but it never shows the correct time, just 0:00 or "opening". But I can never successfully switch songs or pause/play or double click another song. Then, playback stops, and it says "opening" until Ctrl + S (stop). No song will play after this point, until I close the application, end the process (it continues running after closing the software), and reopen it. The above behavior is consistent across multiple software restarts.
[I haven't tested all software components.]
