How to download and install the May 2015 security updates
Updates are already available via Windows Update. Since update checks are not run in real-time, you may want to run a manual check for updates to find and install the updates as soon as possible on your system.
To do that, tap on the Windows-key, type Windows Update, hit the enter-key and click on check for updates in the window that opens.
Cautious users may want to wait with the installation as updates may have unforeseen consequences on systems as the past has shown.
Updates can be downloaded individually from Microsoft's Download Center or via monthly released security images.
You may also find third-party tools like WSUS helpful in this regard.

Great summary and first out…thanks!
Sad to note the perverse trend “using downloadable webfonts as navigation icons. kewlness” has crept into this site’s WP theme.
FYI: For those of us not partaking in superfluous font downloads,

(KB3022345) – Update to enable the Diagnostics Tracking Service.
Gotta love Updates with the word Tracking in them. :/
Is there any more info on this one? MS own page is bare as always.
It is installed as a service. You can set it to disabled and stop it in the Services manager.
Diagnostics Tracking Service : stopped and set to Disabled.
Tracking is everywhere nowadays, so when the system can manage to leave a follower off its track with no collateral damage, I subscribe to having it be shut.
Thanks for the info, Martin, and for the article, precise as always.
I’ve found this article: http://www.infoworld.com/article/2919142/operating-systems/windows-patch-kb-3022345-re-re-released-third-version-of-usage-tracker-in-two-weeks.html
I reset Windows 8.1 last week. I uninstalled Silverlight, did not install other plugins, and did not install any of the 200 Windows updates. This computer has never worked so good. :)
Just wait a few days. ” KB####### Botched Update Causes BSOD on Windows” will be all over the tech blogs.
WTH!!! I have 41 updates!!!
Mine only installed 5 updates and the rest failed.
Trying again, one at a freaking time, in order to see which is causing the failure.
As there are more than 100 hidden services cropping personal data and sending that data 24/7 to Microsoft, what’s the problem adding another one ?
How to identify, still I don’t know, which update is good and which may cause problems.
This update screwed up my system fonts somehow on Windows 7 Pro. All the notifications windows on all programs, but especially on Outlook, show some large fuzzy font as if the original font was deleted. Because the font is now large, the notification windows are gigantic and unusable. I went into control panel, adjusted the fonts to Default, downloaded a list of Windows 7 system fonts, went font by font to make sure they were all installed. Re-booted the computer. Nothing. Even this email looks fuzzy and strange as if the wrong font is used.

Well I discovered that this download mess has killed Windows Live Mail. Now getting JIT Debugger Error and can’t send emails at all. No idea which update caused the problem so not sure what to do to fix it!
Can anybody confirm that “May 2015 XP critical security updates” for customers with CSA still are unavailable?
