I installed QGIS using OSGEO4W, and would love to know how to uninstall it, because when I go to "Control Panel > Programs > Uninstall" the program does not appear in the list of installed programs. How can I do this?

There is not a best way to do it, no 'Add Remove Programs' method. But...

The simplest way is to delete C:\OSGeo4W. This will remove all the installed data. You can also uninstall stuff through the osgeo4w.exe installer.

(From the website:http://trac.osgeo.org/osgeo4w/wiki/FAQ)

Is there a way of uninstalling packages or all of OSGeo4W?

Individual package can be uninstalled via the Advanced install path. In the package listing click on the "New" column until the value changes to "Uninstall". Currently packages do not clean up desktop or start menu icons when uninstalling, this may be done manually.

Currently there is no installer option to uninstall OSGeo4W completely. However, when all OSGeo4W applications, shells and services (like apache) are shutdown it is possible to just delete the whole OSGeo4W file tree (usually C:\OSGeo4W).

See also trac #38 (enhancement).

I assume there are no registry settings created by OSGEO if just deleting the directory is expected to work properly. Is this accurate? –  GeorgeC Aug 7 '12 at 3:00

There is a registry entry under HKLM/Software/OSGeo, which will not be removed by deleting the folder. But this does not bother any other installation. I would recommend the Uninstall option in the installer as mentioned above. –  Andre Joost Aug 7 '12 at 5:08
