QGIS 3.22.3 is available on Windows via the OSGeo4W installers v2/msi 
which also install Python 3.9.

As noted in the download page of the QGIS Web site [1] ("CAUTION: 
Windows 7 no longer works as we are now using Python 3.9, which dropped 
support for it."), Python 3.9 doesn't support Windows 7, so each piece 
of QGIS that needs Python to work will not work.

The Plugin Manager needs Python for most of its functionalities and the 
non core plugins are written in Python, so it is not possible to install 
and use any Python plugin with QGIS 3.22 on Windows 7.
Moreover, the Processing plugin does not work without the Python 
support, so you cannot use any geoprocessing tool.

AFAIK, if you need to use QGIS on Windows 7, you could use QGIS 3.16.16 
installing it via the old OSGeo4W Network Installer (v1) or the OSGeo4W 
Standalone Installer (.exe).

Regards.

Andrea
