Can I stop windows from "Blocking" zip files

Solution 1:

I think this is what you want:

You do not say if you are using a Pro or home version.

If you you have a Pro version, open gpedit.msc (this is not available in home version, but is easier to use) and go to:

User Configuration>Administrative Templates>Windows Components>Attachment Manager

and enable the policy called

Do not preserve zone information in file attachments

Then run gpupdate /force from a command prompt.

If you have a home version of the OS, go to this registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments

and edit the value for key

SaveZoneInformation to 2

You may have to create these keys, and if you want, you can also create them system-wide here:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Attachment‌s
