I just got a notice about a series of updates coming in on "Patch Tuesday" (9 June) of this month. I've looked up some of them and they seem to be somewhat important (I hid all the "recommended" ones which were nothing more than Windows 10 crap), but I'm curious to know what exactly do they "patch" or otherwise do, and how do they do it.
In layman's terms.
Microsoft's security bulletins are too technical for my understanding and I want to make sure I'm not installing adware, nagware, spyware -- or upgradeware.
The updates are:
- KB3058515, Cumulative Security Update for Internet Explorer 11 for Windows 7 for x64-based Systems (and which has apparently had some problems)
- KB3033890, Security Update for Windows 7 for x64-based Systems (apparently something to do with Windows Media Player)
- KB3057839, Security Update for Windows 7 for x64-based Systems
- KB3059317, Security Update for Windows 7 for x64-based Systems
- KB3063858, Security Update for Windows 7 for x64-based Systems
For the first two, do I need to install them if I never use IE or WMP? I actually have them "turned off" (inaccessible) in Programs & Features. Should I install them anyway? Is it likely to cause problems? Is it just a waste of time and drive space since I use Waterfox and VLC and have actually never touched IE and WMP?
With the next three, the articles keep making mention of files or links that are "specially crafted." What exactly does that phrase mean? The last update's info page mentions the possibility of someone putting a hacked DLL on your computer through a remote execution, but it specifically mentions accessing network shares. Can I ignore this last one because I don't have any network shares? Can the DLL come from the Internet too?
Is it OK to install these "important" updates? As I said, I've already disabled the "recommended" ones and won't be installing those. Do any of these contain spyware or nagware?
