Recently I installed a program which changed all my `.apk` files into `.°²×¿Èí¼þ×°ÎÄ¼þ (.apk) (.apk)` files.

**NOTE:** It's only changed the displaying extension of the files, in Windows Explorer. The actual file extension (as discovered via cmd) is still .apk

I tried renaming the file, but that doesn't let me change the file extension.

Is there any way I can change these back into `.apk` files?

I was wondering if you might be able to with the registry editor, or via some sneaky underhand methods.

Please help.
