Is QGIS 32 or 64 bit?

The 64bit version is recommended for almost all users, unless you are attempting to install the software on a extremely old computer that has a 32 bit processor. It is also recommended that you install the latest release rather than the long term release so that you have access to the latest QGIS features.

RAM – 8GB of RAM or higher is recommended for using QGIS and avoiding system crashes. 2. CPU Speed – Higher than 1.9 GHz is recommended, although not required. QGIS might run slow at lower levels.

The OSGeo4W installer is recommended for regular users or organization deployments. It allows to have several QGIS versions in one place, and to keep each component up-to-date individually without having to download the whole package. Since QGIS 3.20 we only ship 64-bit Windows executables.

You will lose and/or have to recreate certain default settings, but fairly often QGIS crashes are caused by something (internal to QGIS, a plugin?) corrupting your user profile.
 

Why does QGIS take so long to load?

Do you need Python to run QGIS?

QGIS tools run based on C++ and not Python, as MrXsquared and marcelo pointed me out. Still, you don’t need to know any programming language to use the tools.
