Here you can download the latest version of 7-Zip. 7-Zip is a file archiver with a high compression ratio. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.

7-Zip is a file archiver with a high compression ratio for ZIP and GZIP formats, which is between 2 to 10% better than its peers, depending on the exact data tested. And 7-Zip boosts its very own 7z archive format that also offers a significantly higher compression ratio than its peers—up to 40% higher! This is mainly because 7-Zip uses LZMA and LZMA2 compression, with strong compression settings and dictionary sizes, to slow but vastly improve density. If a zip tool gains its appeal from its ability to efficiently compress files, then 7-Zip proves it has a little bit o’ magic.

7-Zip

After you effortlessly download and launch 7-Zip, you’ll quickly discover its simple and easy to navigate interface. The main toolbar contains 7-Zip’s most used features and there are several menus that allow you to dig deeper within. For example, the Extract button lets you easily browse for or accept the default destination directory for your file, while the View menu contains a Folder History, and the Favorites menu lets you save up to ten folders. 7-Zip also integrates with the Windows Explorer menus, displaying archive files as folders and providing a toolbar with drag-and-drop functions. You can also alternate between a single or dual-pane view.

Product Details

7-Zip offers several features that make it one of the best compression software options around. For example:

Open architecture—The source code uses the GNU LGPL license, while the unRAR code is under a mixed license with GNU LGPL + unRAR restrictions.
High compression ratio—Using its own 7z format with LZMA and LZMA2 compression, 7-Zip’s compression ratio is up to 40% higher than its peers. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10% better than PKZip and WinZip.
Strong AES-256 encryption—This includes both password protection of files and encryption of file names.
Ability to use may compression, conversion, or encryption methods—For example 7-Zip:Integrates with Windows Shell—Using its menu options, you can integrate 7-Zip to the Windows Shell menu.
- Supports packing and unpacking for 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM.
- Supports unpacking only for ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR, and Z.
- Supports a self-extracting capability for 7z format.
Powerful file manager and command line versions—There’s also a plugin for FAR Manager.
Localizations for 79 languages—This kind of support is why 7-Zip is the world’s favorite free compression software.

One day I discovered Chocolatey:
https://chocolatey.org/

Since that day, updates on free software are no longer a concern.

p.s. - 7-Zip is already updated in the repository - It says version 18.5, and not 18.05 (but it's same thing)

Another reason to upgrade:

The speed for single-thread LZMA/LZMA2 decoding
was increased by 30% in x64 version and by 3% in x86 version.
7-Zip now can use multi-threading for 7z/LZMA2 decoding,
if there are multiple independent data chunks in LZMA2 stream.
7-Zip now can use multi-threading for xz decoding,
if there are multiple blocks in xz stream.
The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.

You know its not remote code execution if you have to download a file first and open it locally. Whats with the security people these days.

Obviously something like 7-Zip which is not a persistent service of any kind will likely never be affected by Remote Code Execution, since remote hackers cannot interact with it whatsoever - unless you have a web-service that somehow interacts with 7-Zip (to unpack uploaded files, for example), but thats reaching.

I use PatchMyPC. Real handy and easy.

Nice tool, but that program is a little toy compared to Choco:

"There are 5762 community maintained packages" (currently)

This one is the Windows equivalent of Ubuntu package manager... it can install, uninstall, update software, look for new software in various categories, etc. I a completely different class than that little tool.

Oh, and there is a GUI as well (which I'm using), so I don't mess around with commandline:
