Hello,

I'd like to disable Windows Zip Functionality as rumour suggest it 'speeds up' the copying/moving of zip-files within Windows.

During cmdlines.txt I remove the below keys:

[-HKEY_CLASSES_ROOT\.zip\CompressedFolder]
[-HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}]
[-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CompressedFolder]

However, when Windows loads and I run regedit.exe the above keys still exist and Windows Zip Functionality works as expected. Even when I delete the above keys manually, Windows Zip Functionality is not effected.

Can anyone offer me a solution please?

I have 7-Zip Installed and no longer require Window's built-in functionality, I would like all references to it removed from my system without the use of nLite.

laze.

You have to un-register the ZIPFLDR dll like this:

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

Hi,

And with that done, is removing the registry entries no longer important?

laze.

Exactly.

Right,

And I will no longer see references to it, for example "right click > new > compressed zip folder"?

laze.

Yup, the reg entries and the right click item will be gone.

Hello,

It appears the registry tweak was working to begin with. The reason Zip Functionality returned was 7-Zip had no file assocation to *.zip files, If I created a dummy *.zip file the *.dll would re-register itself and Windows Zip Functionality would return.

Yeah sorry should have mentioned that.

You need to immediately assign the .ZIP extention to 7ZIP (or alternate) to stop it re-registering that DLL.

Use regsvr32 /u. Then delete or rename zipfldr.dll.

(don't bother renaming or deleting if you have SFC on)

Hello,

Thank you to everyone who contributed to this thread.

I have SFC enabled, I don't want 'hacked files' as part of my installation, assigning *.zip to 7-Zip immediately (as tim suggested) has the same effect.

Cheers.

laze.
