I have a point to raise regarding my own setup. I’ve moved on from 7-Zip and am now using NanaZip—a really great tool. However, what bothers me immensely is the fact that NanaZip associates itself with *.wim files—something that absolutely should not happen. I even had to roll back my system at one point because of this, only to later discover the culprit in the registry: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.WIM\OpenWithList] "a"="40174MouriNaruto.NanaZip_gnj4mf6z9tkrc!NanaZip.Modern" This must not happen under any circumstances; simply right-clicking a `boot.wim` file to open it with NanaZip just once is enough for the entry to embed itself in the registry and create the association. What can I do to prevent my *.wim files from becoming associated with it again—for instance, during a future NanaZip update? I never had these issues with 7-Zip. I also tried using the "Windows default apps" file association settings, but that isn't the solution I'm looking for; it doesn't help me. A *.wim file shouldn't be associated with that by default—unless I specifically configure that setting myself.
