Windows 10 version history


The way Microsoft plans to roll out the next version of Windows 10 this fall is almost certainly a precursor for future autumn upgrades.

Microsoft has acknowledged that this fall"s "feature upgrade" for Windows 10 will be virtually identical lớn the already-available version 1903 released in May.

"19H1 và 19H2 mô tả the same servicing content. That means they nói qua the same Cumulative Update package," Dona Sarkar and Brandon LeBlanc, the spokespeople for Microsoft"s Windows Insider beta testing program, wrote last week in a post lớn their group"s blog.

Sarkar and LeBlanc referenced 19H1 & 19H2 - better known perhaps as 1903 & 1909, respectively, in Microsoft"s four-number labeling format - because their team had just released those builds lớn the Release Pnhận xét ring, where a subgroup of all program participants vị a last chạy thử of betas.

Although Sarkar and LeBlanc did not explicitly say so - Microsoft rarely puts things plainly - their explanation confirmed that the fall "upgrade," 1909, will be nothing lượt thích previous Windows 10 editions. Instead, it will be a barely changed retread of the spring"s 1903.

That Windows 10 1909 will resemble an old style "service pack" was not news: Last month, Sarkar and LeBlanc touted the refresh"s small number of features và their even smaller import. Both were central to lớn the characterization of 1909 as a service paông chồng, as that format rarely included new features but instead collected past updates. (Microsoft"s last service pachồng was for Windows 7, issued in early 2011.)

The two went inkhổng lồ even greater detail about why Insider delivered two builds, 191H/1903 & 192H/1909, to the Release Previews ring.

"For the small submix of Windows Insiders (the 10%) in Release Preview who were given the option khổng lồ install 19H2, an enablement package is downloaded from Windows Update that turns on the 19H2 features," Sarkar and LeBlanc wrote. "This changes the build number for the OS from 19H1 Build 18362 lớn 19H2 Build 18363. Because they use the same servicing content, the build revision number (the number that comes after the dot) will always match between 19H1 và 19H2. As we continue to demo our servicing packages in the Release PReviews ring, Insiders on 19H1 và 19H2 will get a single Cumulative Update with the same fixes."

It"s parsing time

There is worthwhile information in what Sarkar và LeBlanc said in the quotes above. It"s just that it"s buried in terminology no one outside Microsoft"s development team needs to know, surrounded by unnecessary verbiage that few understvà or find useful.

Here are the bits that, teased from the rest, proved important.

19H1 and 19H2 share the same servicing nội dung. This is actually fairly clear; the two "upgrades" 1903 & 1909 that are now being tested và will be released this fall, presumably simultaneously, are identical in content.That means they mô tả the same Cumulative sầu Update package. As above sầu, but particular to packaging. Not only will 1903 và 1909 have identical content but both will come in a single update. (Microsoft has done the same with entire operating systems, where one package can, with the right license keys, install trang chủ or Pro.)As we continue lớn demo our servicing packages in the Release Preview ring, Insiders on 19H1 and 19H2 will get a single Cumulative Update with the same fixes. By combining the two above sầu, Microsoft got to this, which really was all that was needed as explanation. Insiders running 1903 or 1909 get the same update which includes the same fixes. Was that so hard?... an enablement package is downloaded from Windows Update that turns on the 19H2 features. Because Microsoft ships the Cumulative sầu Update - the single package with the 1903/1909 fixes - with new features and functionality in 1909 turned off, systems "upgrading" from 1903 khổng lồ 1909 need some kind of switch thrown lớn activate those features. This "enablement package" is that switch. Systems whose users intkết thúc them to stay at 1903 will not receive sầu this package or signal. (Think of it as more the latter than the former.) Rethành viên, too, that Microsoft has said it will not turn on 1909"s new features immediately for all upgrading PCs, but will, as it already does with feature refreshes, activate 1909 in stages.

Here"s what we know so far about 1909

To recap what Microsoft"s divulged so far:

Microsoft has targeted this month for the release of Windows 10 1909 (yes, that"s official; it was used by Sarkar và LeBlanc in their Aug. 29 blog update.)Windows 10 1909 can be upgraded using the Cumulative sầu Update only on a machine running Windows 10 1903.The "upgrade" khổng lồ 1909 will be identical to the latest update for 1903; both 1903 and 1909 will come in a single Cumulative Update.Windows 10 1909"s new features may or may not be turned on by Microsoft; if they are, it will be with what the company called an "enablement package." Think of it as a downloaded code that frees up the features.Maintenance of Windows 10 1909 will be provided by the usual monthly cumulative sầu updates. They may or may not be identical to lớn what"s served khổng lồ 1903. (The only difference, rethành viên, is that 1909 has a few features that 1903 lacks.)Although Microsoft has said that it is "unknown at this point" whether 1909 is the new pattern for the fall "feature upgrade," don"t kid yourself: This is no one-off but a template for 20đôi mươi & beyond. There"s no way Microsoft would invest this kind of time - và these resources - creating an entirely different kind of upgrade & servicing Mã Sản Phẩm and then use it only once.
