Disable ZIP file handling in Windows XP

I do not want to open ZIP files in Windows Explorer since it takes a long time to open big ZIP files.
To disable the built in support for ZIP files in Windows XP execute the following command in a command window (cmd.exe)

regsvr32 /u %windir%\system32\zipfldr.dll

To enable it again

regsvr32 %windir%\system32\zipfldr.dll
