I'm looking for some software I've used before but can't remember the name. Its something like aup. Its a non-microsoft alternative for doing updates.
there used to be Windizupdate, a service (long discontinued) allowing users to update the system via Firefox.
then there was RyanVM's Update Pack and similar bundles, which are no longer offered for legal reasons.
there are still some non-english bundles regularly updated (e.g. from WinFuture.de).
othere websites like softwarepatch.com offer only crucial security updates, although not bundled.
Well its not discontinued, but the heise.de offline update app should do what you're looking for i think
