[Qgis-user] How to "uninstall\purge" QGIS in Windows

[Alexandre Neto]

I'm having problems with my installed version of Quantum GIS (Union
does not work) in windows. I came to understand that its probably
something about my installation. And that developer version of QGIS
will work correctly.

So, I wanted to fully uninstall QGIS (previously installed by
osgeo4w). I have uninstalled all software, and erased the OSGEO
folder. But when I install the sofware, alll my installed plugins are
still there, and the union is still not working in the new installed
QGIS (1.9.90).

So, how can I fully uninstall QGIS?

Thanks!
