For zip files delete the regkey HKEY_CLASSES_ROOT\CLSID{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}
When you try to delete them, you will almost certainly get an "access denied" or "failed" type of message. Before you can delete them, you need to change the permissions/ownership of these two keys. Here is how to do it:
01 - open regedit from the RUN console
02 - navigate to the first key that needs to be deleted (HKEY_CLASSES_ROOT\CLSID{E88DCCE0- B7B3-11d1-A9F0-00AA0060FA31})
03 - right click on the key and select "Permissions"
04 - click on "Advanced"
05 - click on the "Ownership" tab
06 - in the "change owner to" section, highlight your username
07 - check the box for "replace owner on subcontainers and objects"
08 - click on "Apply"
09 - Click "OK"
10 - Under "Security" tab, highlight your username and check the box for "Allow Full Control" (located mid-menu in the "Permissions For Administrators" section)
11 - click "Apply" and "OK"
12 - you can now delete the registry key. MAKE SURE YOU ARE ON THE CORRECT KEY!
13 - repeat the process for the 2nd key.
14 - reboot (changes will NOT take effect until you reboot
15 - VOILA! NO MORE ZIP FOLDERS! woohoo!
16 - thanks to the original solvers of this problem, whomever they may be.
