Pure version, original version. These two seem to be the same thing, unless the original refers to the original, but if it is the original, it needs a key, which is very troublesome ~

No plugin, no optimization, no deletion ~ ~

Streamlined: there are deletions.

Optimized version: it may be deleted, and the service will definitely change.

Classic edition: I don't know much. Some people may think that it is well done and have such a name.

Enhanced version: it will definitely let you install a lot of software, whether you use it or not ~
