The title says it all.
I can't find Skyrim in the uninstallation list at "Control Panel\Programs\Programs and Features"; I can only find Steam there.
I want the game deleted from my harddrive, in order to then reinstall the game, and see if a problem gets fixed by doing this.
Steam based games (non Valve ones) are located in
\Steam\steamapps\common\
To uninstall the game, simply load Steam (client) and click on your Library. Right-click on the game, and select:
Delete Local Content. This will remove the game from the previously mentioned directory. To reinstall simply click on the Skyrim icon in the Steam Library and select Install. You may also use a Skyrim Install Disc.
