Why Should You Upgrade to 7-Zip 25.00 for Better Performance and Security?
7-Zip 25.00 brings meaningful changes for users who need fast and secure file compression. The update focuses on making the program work better with powerful computers and improving how quickly files get compressed. This guide explains what’s new, how it helps, and why updating matters.
What’s New in 7-Zip 25.00?
Support for More CPU Threads
7-Zip now works with CPUs that have more than 64 threads. High-end processors like AMD Ryzen Threadripper (up to 128 threads) and some Intel Xeon models can now use 7-Zip’s full power. Most home computers do not have this many threads, but for those who do, compression and benchmarks run much faster.
Faster Compression Speeds
bzip2 compression is now 15% to 40% faster. Deflate method (used for zip and gz files) is 1% to 3% faster. These improvements mean you spend less time waiting for files to compress, especially when working with large archives.
Better Archive Support
Improved handling of ZIP, CPIO, and FAT archives. These changes make it easier to work with different file types and formats.
Bug Fixes and Security Updates
The update fixes several bugs, though details are not listed. Some security issues have been addressed, but the specifics are not public.
In the past, 7-Zip was targeted by hackers using a vulnerability called Mark-of-the-Web Bypass (CVE-2025-0411). This allowed attackers to bypass security checks in 7-Zip 24.08.
The developer patched this issue in version 24.09 after security experts reported it.
Why Security Updates Matter
7-Zip is a popular tool, making it a target for cyber threats. Even if the latest security fixes are not detailed, updating ensures you have the best protection. Using outdated software increases the risk of your files being exposed or corrupted.
How to Get 7-Zip 25.00

Upgrading to 7-Zip 25.00 is a smart choice. The update makes file compression faster, adds support for the latest hardware, and keeps your files safer. Even if you don’t have a high-end computer, you’ll notice better performance and reliability. For users who handle lots of files or care about security, updating is essential.
