How Unzip a 7z File With Windows 10?

I'm trying to unzip a 7z file and Win10 is not giving me a way to do it automatically.

I double click on the file in File Explorer and nothing happens. In the menu above, I see a way to zip files, but not to unzip a file.

I googled it and the results tell me to use third party software.

I thought Win 10 had an unzipper built in.

Windows has zip file built in. Not 7zip support.

7z is a format produced by 7-Zip, you'll need it to open the compressed file.

7z is a compressed archive file format that supports several different data compression, encryption and pre-processing algorithms. The 7z format initially appeared as implemented by the 7-Zip archiver. The 7-Zip program is publicly available under the terms of the GNU Lesser General Public License.

Thanks.
I got an unzipper from sourceforge that did the trick.
