 ## Remarks
 
-This warning is triggered when an uninitialized `VARIANT` is passed to an API such as `VariantClear`
-that expects an initialized `VARIANT`.
+This warning is triggered when an uninitialized `VARIANT` is passed to an API, such as `VariantClear`, that clears the object. Initialize the `VARIANT` before passing it to these functions so it can be properly cleared.
+
+This warning applies to these functions:
+
+* `VariantClear`
+* `PropVariantClear`
+* `VariantCopy`
+* `VariantCopyInd`
+* `VariantChangeType`
+* `VariantChangeTypeEx`
+* `DestroyPropVariant`
 
 Code analysis name: `VARIANTCLEAR_UNINITIALIZED`
 
 ## Example
