OSGeo4W shouldn't use anything from outside OSGeo4W and doesn't put anything in
PATH or the system apart from the (usual) MSVC runtimes.  So installing
everything QGIS depends from OSGeo4W shouldn't cause problems.

But using QGIS with something is wasn't built with might.

Uninstall all packages using the installer and then remove the osgeo4w
directory.   Just removing the OSGeo4W directory will leave the desktop icons
and start menu entries around - but otherwise shouldn't do any harm.
