One thing in Windows XP really shits me - the Find prompt in Windows Explorer. In Win2k it's utilitarian and quick to use. In XP it's a bunch of extra clicks and an overexcited animated dog.
But, thankfully, you can get the Win2k style back. I happened to find this today... wish I'd had a look sooner!
Get Tweak UI - http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx. Then run Tweak UI → Explorer → Use classic search in Explorer. While you're there, check out the Group Policy editor.
Update 2009.05.01: if you want to get rid of Windows Search and get classic search ("search companion") back...
- Start → Run
regsvr32 /u "%programfiles%\Windows Desktop Search\wdsShell.dll"
- hit OK
After a restart you should be back to normal.
