1. Is not v6.11 much outdated? The latest is v6.13 as of July 4th, 2018. 2. How to keep portabolized EN updated? You cant. Just need to make another portable from a newer setup version. This means notebook has to be synchronized anew. 3. If standard EN updates run under Sandboxie... would this not also accomplish also keeping WIN 10 OS registry-FREE and clean? Portable version does not add anything new into the registry.
i made my own 'portabolized' version of v6.11 (June2018), run from usb or sd card or pc, if you are interested.
