One of the most essential tools in any power user’s toolkit just got a serious upgrade. You see, 7-Zip 25.00 is here, and it delivers better speed, smarter CPU usage, and important fixes that make it worth the update.
The most notable improvement is that 7-Zip can now take advantage of more than 64 CPU threads. This matters for high-end systems running Windows, especially those with many cores like AMD Threadripper or server-class machines. In earlier versions, 7-Zip was limited to a single processor group, which meant some threads went unused. With this update, the software spreads compression workloads across multiple groups, leading to better performance when handling large archives.
There are also compression speed boosts across the board. The bzip2 algorithm is now faster, with improvements ranging from 15 percent to 40 percent depending on the data. Deflate, which powers zip and gz formats, saw a smaller gain of about 1 to 3 percent. While not game-changing on their own, these upgrades can save real time when processing lots of files.
This release also improves support for ZIP, CPIO, and FAT archive formats. On top of that, a number of bugs and vulnerabilities have been addressed, which is important considering how widely 7-Zip is used in system administration, scripting, and packaging workflows.
Even after all these years, 7-Zip remains completely free and open source. It avoids unnecessary bloat, stays lightweight, and works without getting in your way. While users on Linux and macOS often have other tools at their disposal, Windows users in particular should not skip this version.
