Edit:
Updating 2 more machines in Dev channel.

Thank you for the insider information. Sadly, I don't like Windows Defender. I use BitDefender. Microsoft Defender is still active. It still updates itself. Bitdefender is constantly ranked in the top 5. Microsoft isn't. Different organizations are somewhat biased and change the rankings, mainly based on the subsidies they receive from sales of the various products. I've never had any problems with malware, phishing, etc., using Bitdefender. I also use its VPN. It comes with Premium. It also includes PC tools to clean up files left in the temps, etc. So does Nord VPN. I have both.
I actually use Ashampoo WinOptimizer 28 to remove unnecessary files and then clean the registry—German excellence. Sometimes Windows reports errors after deleting files and uninstalling apps. So I wait until the apps and extra files are removed from the many temps, then I clean the registry. I've used all 3 to easily make a few tweaks for custom personalizations. I've heard many people say that Windows does a fine job with everything. If you're happy, I'm happy that you are. I do know that the larger the registry becomes, the slower the computer runs. If the information is incorrect, it can cause major problems. I had a power interruption, and my computer turned off. Windows said there was a problem with my C drive. I checked it using chkdkk from the command prompt. It reported many errors, including the fat bitmap being wrong.
Everyone knows, and it even states that if you run it from Windows, it would report nonexistent errors. I became paranoid. After booting into DOS and running chkdsk /f /r as someone suggested, it found no problems. I should have remained calm. Thought logically, and ran chkdsk /f. That should have been enough. It was. It went so fast and reported no errors. Win 10, backwards showed a summary after running chkdsk from DOS. That's when I reran it with the /r switch. This hard drive has no problems except that Windows incorrectly reported the location of one file after an improper shutdown. I easily corrected it. Chkdsk shows no errors inside Windows. I've said too much.
I purchased long-term subscriptions around December, when you can buy 3 to 5 years of both at a very low cost. I'm sure most people know that October through December is usually the best time to purchase discounted software, etc. I also love Mozilla Firefox and RoboForm password manager. I have a lifetime subscription to RoboForm. (Same with I.D.M.) I've never had an account hacked because someone discovered my password. You'd need an incredibly fast computer to discover 26-or-more-character combinations of unique passwords. It would take months or years. Hackers use random character password generators. They keep trying different combinations. Hackers suck! Straight from God's Holy Bible, "For the love of money is the root of all evil." Get a life, please. Criminals are evil. They're lazy. They want to obtain money as easily as possible. Some are relatively intelligent and smart. If they put their intelligence and knowledge to work to better the world, it would be a much better world. Same with I.D.M. I like Windows 10 and older the best. The simpler the better. As I'm sure you know, Apple is the best. That's for rich people, though. Sadly, hackers are now attacking Apple. It used to be totally secure. It didn't need extra protection. Please watch " Pirates of Silicon Valley" https://www.imdb.com/title/tt0168122/ if you're interested in the true history of Apple and Microsoft. It's a great movie for PC enthusiasts. These are only my opinions. I'm sure many of you are much more knowledgeable and more intelligent than I am. I only have a high school diploma. I do, however, have an I.Q. of 138. (100 is average, 150 is genius.) I joined the U.S. Army after high school. I don't have formal college training. But I've learned quite a lot on my own, so I'm fairly smart. I earned an A on the Big Bang Theory and the Theory of Evolution. I know God is 100% real, and there is a Heaven and Hell. I know where I'm going to be for eternity. I love God and everyone. May our Father, God, continue to bless and protect everyone. Thank you, Jesus, for everything. Amen.

Is anybody getting back this Administrator Protection feature?
No signs of it on any of my machines yet.

[Administrator Protection]​

Administrator protection is being re-enabled and aims to protect free floating admin rights for administrator users, allowing them to still perform all admin functions with just-in-time admin privileges. This feature is OFF by default and can be enabled via OMA-URI in Intune or via group policy.

It looks like the ability to remove unwanted quick actions from Windows 11's quick settings menu is finally returning!

Hidden in build 26300.7965 is an updated energy saver quick setting which supports this (removing it doesn't work just yet, though). Hopefully more follow suit.

The updated quick setting has also been turned into a split toggle with a currently blank subpage, energy recommendations will likely be displayed here in a later build.

vivetool /enable /id:59956305,59149945

The (still hidden) migrated "Change account name" option in Settings now works properly in build 26300.7965!

When the upcoming agenda view in notification center (still not rolling out!) first showed up in builds late last year, there was no way to hide it.

Newer builds now have an option to show/hide it which can be found next to the date.
