Manufacturers need to distinguish between critical updates that fix a significant error in the results or fix a security hole that could make the users system vulnerable. By contrast, feature updates should be labeled as such. This makes it easier for the user to make an informed choice to install the update.
Manufacturers seem to be hip to this which is why they bundle critical security updates with UI changes and other trash that you don't need. If not for that nobody would upgrade... it's totally backwards.
