Microsoft Security Updates April 2017 release

Microsoft released security updates, and non security updates for all supported versions of Microsoft Windows and other company products today.
The April 2017 Patch Tuesday is special. First, because it marks the end of Windows Vista's extended support phase. Microsoft won't release security updates for Windows Vista officially anymore.
Second, it marks the beginning of the roll out phase of the Windows 10 Creators Update.
Our guide provides you with information on today's Patch day. It begins with an executive summary that lists the highlights of this month's Patch day.
We had to change the guide somewhat this month as Microsoft moved from offering information in security bulletins to using the Security Update Guide website exclusively. This makes it more difficult to gather information for this overview as you get a lot of noise in the listings.

Some updates are also available on the Microsoft Download Center website.
To check for updates using Windows Update, do the following:
- Tap on the Windows-key, type Windows Update, and select the item from the results.
- Click on check for updates button if update checks don't run automatically. Windows should list all new updates available for the system.
- Updates may be downloaded automatically, or on user request then.

Martin, I would appreciate that you do not censor this post, as it’s informative writing.
Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).
For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.
You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.
If you used AI to help write this article, it has failed miserably.
EMRE ÇITAK posts are useless because they are fraught with inaccuracies and are irrelevant.
AI is stupid, and it will not get any better if we really know how this all works. Prove me wrong.. https://www.youtube.com/watch?v=4IYl1sTIOHI
Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.
Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.
Don’t tell me!
Ghacks wants the state to step in for STATE-MANDATED associations to save jobs!!!
Bring in the dictatorship!!!
And screw Rreedom of Association – too radical for Ghacks maybe
GateKeeper ?
That’s called “appointing” businesses to do the state’s dirty work!!!!!
But the article says itself that those appointed were not happy – implying they had not choice!!!!!!
Rreedom of Association is one of our most important rights. Some people think it’s Freedom, but no, I say Rreedom is far more important. There are many STATE-MANDATED associations that save jobs, that’s right MANDATED. I can’t name any of them, but rest assured they are bad, because saving jobs are bad, and people having jobs leads to dictatorship!!! Anyone who disagrees is too radical for Ghacks maybe, because I’m not sure.

As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.
“Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”
Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
No, they didn’t lmao.

What does this article about Musk/Tesla have to do with computing, devices, phones?
More irelevant filler.
yeah sure… they are always the victims and it is only against them ????
Believe them 100% and never question anything. This lawsuit sounds like the type you heard when people were eating batteries.
