Now Windows has 10 updates for C, B and D. What is the smoking of Microsoft?

According to Microsoft, there are 10 updates for "B", "C" and "D" in Windows – but never "A"! These updates are released at different times, contain different things and are offered to different people. Let's reduce all this.

What is a cumulative quality update?

Microsoft calls these "quality updates" and each is published once a month. This sets them apart from the big "feature updates" such as the October 201

8 update and 19H1, which appear every six months, usually in spring and autumn.

Quality updates are cumulative, that is, they contain all the fixes from previous updates. So, if you install the December Cumulative Update, you'll get the new December security updates, as well as all updates from the November and October updates, even if you have not installed these earlier fixes.

When you upgrade a new PC, you only need to install a large cumulative update package. You do not need to install and restart updates one at a time.

That's great, but the way Microsoft handles C and D updates is just bizarre. Microsoft gets people calling it "seekers" to install the updates before they're fully tested. But hardly any of these people know that they register as "seekers".

"B" Updates: Patch Tuesday

The big updates that most people are familiar with come out "Patch Tuesday," the second Tuesday of the month. Because updates are released in the second week of the month, this explains why there are no A updates because Microsoft updates are not normally released in the first week of the month.

B updates are the most important updates with new ones They also include previously released security updates from earlier B updates and previously released bug fixes from earlier C and D updates.

They are the most important and important type of Windows Update. They are also predictable for system administrators who know when to expect them.

Updates for "C" and "D": "Optional" Preview Updates

Updates for "C" and "D" are published in the third and fourth weeks of the month do not contain any new security updates.

These updates contain only new fixes and improvements for other non-security issues. According to Microsoft, C and D updates are "optional" and are not automatically installed on your PC by Windows Update.

According to Microsoft, "D" updates usually include most non-security updates. This will give people some weeks to test them before releasing these non-security fixes in the next B update for all. Microsoft sometimes releases "C" updates for Windows 7, Windows 8.1, and earlier versions of Windows 10 in the third week of the month, giving users more time to test them.

"C" and "D" updates are there Unwitting Seekers

It gets ugly here: Windows Update does not automatically install C and D updates on most PCs. However, it will install C and D updates if you go to Settings> Update & Security> Windows Update and click Check for Updates. In the world of Microsoft, this will make you a "seeker" who wants to test these updates in front of most Windows users. Microsoft has published this in a recently published blog entry.

So, if you click Check for Updates in the third, fourth, or first week of the month before the next B update, you probably get a C or D update installed on your system. If you never click "Check for Updates", you will stick to the better-tested B.

After these updates were "tested" by the unwanted installation on Windows 10 PCs and Microsoft confirmed that they are stable In telemetry Windows 10 will display the fixes in these updates in the next B update. The C and D updates are essentially beta testing programs for B updates that run on stable PCs.

In other words, Microsoft uses people who click the "Check for Updates" button as a beta tester for quality fixes, rather than relying on the Windows Insider program and the Release Preview ring. It's bizarre, and it's the same bad decision with which Microsoft introduced the unstable update for October 2018 for many Windows 10 users who did not want it.

It's not just a theoretical problem. Microsoft recently had to block KB4467682, a "D" update that caused blue screen crashes on its Surface Book 2 devices. People who never clicked "Check for Updates" and stay with the B updates would not have experienced this issue.

Microsoft has repeatedly stated that only "experienced users" click the "Check for updates" button, but this warning only appears in blog posts that only advanced users can read. The default Windows Update screen in Windows 10 does not contain such warnings. It's ridiculous, but this is how Windows 10 works.

Out-of-band updates: urgent patches only

Microsoft occasionally also publishes "out-of-band" updates. These are urgent patches that do not conform to the normal publishing schedule.

For example, if a major new security bug needs to be resolved, or a problem occurs that causes some Windows 10 PCs to blue-screen, this error can be fixed with an instant patch. This means that everyone receives the fix as soon as possible.

Fixes in out-of-band updates will also appear in the next cumulative update. So when an out-of-band update was released in late December, it also appears in January Update B by Patch Tuesday.

Feature Updates: Big Updates Every Six Months

There are also "feature updates" that are major updates for Windows 10 and are released every six months. These differ from the monthly "quality updates". These are essentially new versions of Windows 10, and Microsoft is gradually phasing them out on PCs.

The most recent major update was the October 2018 update of Windows 10, which did not include the release. The preview ring was not properly tested by Windows insiders before Microsoft released it to people who clicked on "Check for Updates." "clicked. Microsoft likes to abuse the "Check for Updates" button.

Microsoft had to download the update to delete some files and still fix bugs over two months later, although technically it is considered stable and is slowly available to a small number of Windows 10 users.

This would all be much more useful if Windows Update a better user interface that tells people exactly what they are getting into. Users should not accidentally become testers simply because they regularly click the "Check for updates" button. If that's the way the "Check for updates" button works, Microsoft needs to show a big warning about it in the Settings app, not just in blog posts.
