I'm currently migrating from my old notebook to the new one. Here's a trick I've found regarding the Windows XP built-in zip utility. My major problem with the Windows XP zip functionality is that when you view a folder in Explorer the zip files in that folder a are listed as zip folders. Now, if you're like me and like to keep an archive of downloaded files the explorer tree will start to get real long. So here's how you turn off the built-in zip utility.
In the Run dialog box type regsvr32 /u %windir%\system32\zipfldr.dll. Then, rename the %windir%\system32\dllcache\zipfldr.dll to zipfldr.dll.remove. Also rename the %windir%\system32\zipfldr.dll to zipfldr.dll.remove.
You can now install your favorite zip utility with confidence.
