Improve performance of Windows 7 by disabling indexing and integration with ZIP and CAB archives.

As with previous Windows versions, Microsoft has built-in ZIP and CAB file integration which automatically adds archives as folders in Windows Explorer and defaults to searching for files located within. If you don't want this to happen, you can drastically improve system performance by disabling zip files feature.

As with previous versions of Windows, Microsoft does not provide a method by which you can turn this feature on or off, but there is a simple registry hack that will fix things for you.

The easiest way of disabling zip folder integration in Windows 7 is to copy the registry entry below, save it to your desktop as a text file with a .reg extension, then import the contents by double clicking it.

All this does is delete 4 registry keys which removes the association. You can also use regedit.exe to navigate to these keys and delete them yourself. You will need to reboot your computer for the changes to take effect.

Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\CompressedFolder\CLSID]
[-HKEY_CLASSES_ROOT\CABFolder\CLSID]
[-HKEY_CLASSES_ROOT\System\FileAssociations\.zip\CLSID]
[-HKEY_CLASSES_ROOT\System\FileAssociations\.cab\CLSID]

To re-enable ZIP folder integration, you can import the following code in the same way which will relink ZIP and CAB archives to the integration of Windows Explorer

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\CompressedFolder\CLSID]
@="{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}"
[HKEY_CLASSES_ROOT\System\FileAssociations\.zip\CLSID]
@="{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}"
[-HKEY_CLASSES_ROOT\CABFolder\CLSID]
@="{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}"
[-HKEY_CLASSES_ROOT\System\FileAssociations\.cab\CLSID]
@="{0CD7A5C0-9F37-11CE-AE65-08002B2E1262}"

Remember to reboot your computer for the changes to take effect.
