How to disable Windows built-in Zip support

Windows offers the feature to compress files by supporting Zip functionality. While it is a very useful feature, if you are already using some third-party compression utility, some of may want to disable Windows built-in Zip support, and let the external zip program be associated with the zip file format. In this post let us see how to disable this Windows built-in ZIP functionality.

In Windows XP, this solution worked. All you needed to do was to unregister a dll file. Open the Run box, type the following and hit Enter:

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

To enable the built-in zip capability, run the following command:

regsvr32 %windir%\system32\zipfldr.dll

This may not work in Windows Vista and later, as unregistering of that particular dll file is unsupported in these later operating systems, like Windows 7 and Windows 10/8. If you try it, you will receive an error message.

The Windows Registry may not allow you to delete these keys easily. You may need to take ownership of these registry keys. I suggest you use our RegOwnIt to do so easily.

If you have another zip or file compression software installed, you may want to consider disabling this built-in zip support, to save some resources.

Goes without saying – create a system restore point first!
