Statistica users of Statistica frequently encounter the problem that Statistica constantly cluttering the Windows context menu by adding files to the "new" context menu for creating new files. In particular, Statistica-related extensions like str,.sti,.svc,.svd,.sdm,.sta,.smx,.stg,.svb,.stw,.svx.



It can be resolved by the following steps - 

• Open the Windows registry. You can do this by typing “registry” into the Start menu or pressing the Windows key + R and typing “regedit.” [Take a backup of registry editor]
• Navigate to and expand the folder HKEY_CLASSES_ROOT.
• Next, you have to look for the item you want to remove. For instance, if you’d like the Statistica graph removed from your New context menu, look for the .stg extension/folder. If it’s the Statistica workspace you want to delete, look for the .sdm extension/folder.
• Expand the respective folder and look for a key entitled ShellNew.

• Deleting this key will remove the item from your Windows New context menu
• Alternatively, you can rename a key by adding an underscore before its name instead of deleting it. That way, you’ll still have the original key and its contents, and you’ll be able to revert to the default if you choose in the future.
• Close the registry editor.
• Refresh or reload File Explorer
