I was reviewing my Windows update history and found a lot of updates listed as "optional". This is strange because eveytime I receive the prompt that new updates are available, I only install the ones marked "important". When I click on my list of installed updates (where you can delete them) the list looks completely different amd they are not listed as important, recommended, or optional here. Is there a way to remove thes optional updates to free up hard drive space or is it a waste of time? Are these updates taking up enough space to make it worth the while to jump through all the necessary hoops to uninstall them?
