I thought I'd provide a list of software that works Vista RC1.  The following software has been tested on my IBM X41T with RC1:

 

1. WinRAR 3.60

2. AVG Antivirus 7.1 (free edition)

3. FeedDemon

4. Flashget (though I had to turn off the protected mode in IE7)

5. Beyond Compare 2 (I recommend using this program for large file copies since I' ve experienced problems copying large files [> 1gb] from machine to machine.)

6. Magic Disk (run this in compatability mode, Windows XP SP 2)

7. Magic ISO (BTW Nero 7.x doesn't work)

8. Advanced WMA Workshop (warning about WM encoders on install but it appears to work fine)
