Release date: September 16, 2026

WinZip 77.2 builds on WinZip 77.1.
New features
-
Authenticated encryption with AES-256-GCM. WinZip encrypts using AES-256 in Galois/Counter Mode, replacing AES-CTR with HMAC. GCM encrypts data and verifies its integrity in a single operation. AES-256-GCM is available in all WinZip editions and is selected in the encryption settings.
-
Activity logging. WinZip can record the file operations it performs to the Windows event log, including opening and closing files, adding, extracting, renaming, and moving files between folders.
-
Signed executable verification. WinZip verifies that its own program files carry a valid signature each time the program starts. If any file fails verification, WinZip does not run.
Security
-
Software update platform. Security improvements to the WinZip Software Update Platform, which delivers updates to installed clients.
-
Application security assessment. An application security assessment was completed against the codebase, with all findings remediated before release.
Changes and removals
-
ZipShare. Promotional references to ZipShare have been removed from the application.
Installation and upgrade
-
Encryption settings. AES-256-GCM is not applied to existing archives. Archives created or updated after the encryption setting is changed use AES-256-GCM.
-
Activity logging. Logging must be enabled before events are recorded. No events are written for activity that took place before it was turned on.
