How to download and install the March 2020 security updates
Security updates for all supported version of Windows and products included in Windows, e.g. Microsoft Edge, are made available via Windows Update, WSUS, and other update distribution systems. Administrators may download standalone patches to systems to apply these directly without using Windows Updates.
We recommend that backups are created of important date or, better, the entire system, before patches are installed.
Do the following to check for new updates:
- Open the Start Menu of the Windows operating system, type Windows Update and select the result.
- Select check for updates in the application that opens. Updates may be installed automatically when they are found or offered by Windows; this depends on the operating system and version that is used, and update settings.

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.

Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

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”).
RSS Guard: Feed reader which supports RSS/ATOM/JSON and many web-based feed services.

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.
