Windows 1.0 Development Release 4

Windows 1.0 Development Release #4 was the fourth release in a series of development releases of Windows 1.0, which was compiled on 31 August 1984, with several hundred copieshttps://drive.google.com/file/d/1QLqbhKoHxLAKAsZHCdrjb7-UBv_ag50e/view?usp=sharing being distributed to developers in the following weeks. Photos of this build's installation media and release notes were posted by BetaArchive member Allosgroup in July 2021 together with the inventory list, release notes and directory listing of the disks.https://www.betaarchive.com/forum/viewtopic.php?f=59&t=42796 Similarly to the next release from October, it comes on three 360k disks.
According to the available release notes, this release added support for cooperative multitasking, the ability to paint filled ellipses and rectangles among other GDI improvements, and Atom functionality. It also introduced a new resource compiler (RC.EXE) along with changes to the resource script syntax.

Windows 1.0 Fall COMDEX Press Material build

The Windows 1.0 Fall COMDEX Press Material build is a very early pre-release build of Windows 1.0, shown on the press material for Fall COMDEX 1983.https://www.betaarchive.com/forum/viewtopic.php?p=296645#p296645 This build appears very similar to the Personal Computer News 1983-12-01 build, but a new command, run, was added to the command-line shell.

Windows 1.0 Fall COMDEX build

The Windows 1.0 Fall COMDEX build is a very early pre-release build of Windows 1.0, demonstrated on 29 November 1983 at Fall COMDEX 1983,https://youtu.be/vnDRw8-caxU?t=413 although an earlier demo was shown in BYTE magazine the following month. Additionally, builds that are visually very similar to this COMDEX build have been featured in various computer magazine issues from November 1983 onwards.
Windows was also demonstrated by Wang,https://youtu.be/hrgwliaIYTQ?t=1424 Zenith Data Systems,https://archive.org/details/byte-magazine-1984-03/page/n355/ Honeywell,https://archive.org/details/PersonalComputerWorld1984-02/1984-02/page/18/ and possibly by other OEMs as well, though it's unknown if these are the exact same build or not.

Windows 1.0 In*a*Vision 1.01 runtime build

The In*a*Vision 1.01 runtime build of Windows 1.0 is a September 1985 build used as the runtime for Micrografx's In*a*Vision 1.01 software. It was uploaded online on 23 June 2024.https://archive.org/details/invis-x
It is the earliest known Microsoft Windows build to be released publicly, predating the official release of Windows 1.01 by two months.
== Easter egg ==
It contains an easter egg: its bitmap 1 resource in USER.EXE contains only the obfuscated credits text, by a rolling XOR (start key at 0x4D, XOR byte of ciphertext with key, XOR key with plaintext byte, stop if plaintext byte is 0x1A).
The credits text is identical to that of Windows 1.01.

Windows 1.0 InfoWorld 1983-11-21 build

The Windows 1.0 InfoWorld 1983-11-21 build is a very early pre-release build of Windows 1.0, originally shown in an article about Microsoft Windows in the 21 November 1983 issue of the InfoWorld magazine.https://books.google.com/books?id=uy8EAAAAMBAJ&pg=PA32&redir_esc=y#v=onepage&q&f=false The article mentions that the build was demonstrated for InfoWorld at Microsoft's offices in Bellevue, Washington. The system date in the photos is 14 November 1983, presumably the day the demo took place. A third photo in the same article appears to be of a different, earlier build.

Windows 1.0 InfoWorld 1985-07-01 build

The Windows 1.0 InfoWorld 1985-07-01 build is a pre-release build of Windows 1.0 shown in the 1 July 1985 issue of InfoWorld.https://books.google.com/books?id=EC8EAAAAMBAJ&lpg=PP1&pg=PA16#v=onepage&q&f=false It closely resembles the May Beta, but the MS-DOS Executive still displays the free disk space remaining above the file list like the Alpha Release (most of it is covered up by the Special menu, though). The Clock icon is slightly different as well, and the new Calculator has two "M-" buttons instead of an "MC" button at the top and "M-" at the bottom.

Windows 1.0 PC Mag 1985-08-20 build

The Windows 1.0 PC Mag 1985-08-20 build is a pre-release build of Windows 1.0 shown in the 20 August 1985 issue of PC Mag.https://archive.org/stream/PC-Mag-1985-08-20#page/n37/mode/2up/ Windows Write is also shown in the photos, even though it was not included with the May Beta nor the Premiere Edition.
The Calendar application has been redesigned since the Beta, and the system date displayed there is 27 June 1985, so assuming the photos were taken that day, this build would predate the Premiere Edition by at least a month. Various UI details in the Control Panel application also suggest it was made between the Beta release from May and PE from July.

Windows 1.0 Personal Computer News 1983-12-01 build

The Windows 1.0 Personal Computer News 1983-12-01 build is a very early pre-release build of Windows 1.0, originally shown in issue 39 of Personal Computer News from 1 December 1983.https://archive.org/stream/PersonalComputerNews/PersonalComputerNews039-07Dec1983#page/n5/mode/2up/ The photo is of somewhat poor quality, though the observable UI details suggest this build is likely earlier than the one shown at Fall COMDEX 1983, and probably related to the build shown in the third photo in the 21 November 1983 issue of InfoWorld. 
The same photo was also featured in the 24 January 1984 issue of PC Mag,https://books.google.com/books?id=kSzKzjWHeVEC&lpg=PP1&pg=PA34#v=onepage&q&f=true January 1984 issue of Data Processing, February 1984 issues of Creative Computinghttps://archive.org/stream/creativecomputing-1984-02/Creative_Computing_v10_n02_1984_Feb#page/n75/mode/2up and Practical Computing,https://archive.org/stream/PracticalComputing1984February02/Practical%20Computing%201984%20February%2002#page/n83/mode/2up/ and the April 1984 issue of InfoWorld.https://books.google.com/books?id=jC4EAAAAMBAJ&dq=infoworld&q=windows#v=onepage&q&f=false Some of these issues include additional photos that are likely either from the same build or a related build.

Windows 1.0 Preliminary Version 0.50

Windows 1.0 Preliminary Version 0.50 is a pre-release build of Windows 1.0. Lucas Brooks found the logo file for this build on disk 3 of Premiere Edition on 19 June 2020.https://www.betaarchive.com/forum/viewtopic.php?p=451569#p451569 With some help from jb881122, the file WIN256.COM (similar to WIN.CNF in later builds) was recovered, as well as part of a fragmented WIN100.EXE, which includes the complete (although fragmented) MSDOS.EXE and MSDOSD.EXE.
This build may have been made around early June 1985, based on MSDOS.EXE's features and strings, other files found alongside it (including an earlier version of the Calendar program found on Premiere Edition and later), and directory entries found on Premiere Edition disks.https://www.betaarchive.com/forum/viewtopic.php?p=452166#p452166

Windows 1.0 Science et Vie Micro build

The Windows 1.0 Science et Vie Micro build is a pre-release build of Windows 1.0 shown in several issues of the French magazine Science et Vie Micro throughout 1985. A total of four photos were published in three issues.http://download.abandonware.org/magazines/Science%20et%20Vie%20Micro/svm_numero017/SVM_17p0159.JPGhttp://download.abandonware.org/magazines/Science%20et%20Vie%20Micro/svm_numero017/SVM_17p0162.JPGhttp://download.abandonware.org/magazines/Science%20et%20Vie%20Micro/svm_numero019/SVM19_p0000053.JPGhttp://download.abandonware.org/magazines/Science%20et%20Vie%20Micro/svm_numero020/SVM20_p0073.JPG
Visually it appears very similar to the Alpha Release, but features two new applications, namely Cardfile and Windows Plan. The latter looks like a straight port of Multiplan for Macintosh, which was ultimately never released, though an identical looking application called Spreadsheet is again seen in the Application Style Guide of version 1.03 SDK documentation.https://archive.org/details/win103-sdk-manuals/6%20-%20Application%20Style%20Guide/page/n15/mode/2up Clipboard, MS-DOS Executive, Clock, Calculator, Sample Font Application and Cube can also be seen. Calculator has not been redesigned yet, while Paint features a somewhat different toolbar than in the Beta, but is otherwise the same as in the Alpha. Clipboard's executable, CLIP.EXE, has not been renamed to CLIPBRD.EXE yet and still has a menu bar.
The source code of the Cardfile application is included in the software development kit for version 1.01 and later. Its icon file, CARDFILE.ICO, is dated 1 April 1985, suggesting that Cardfile may have been developed around that time (or at the very least, its icon was last changed on that date).

Windows 1.0 September 1985 builds

The Windows 1.0 September 1985 builds were several sets of builds of Windows 1.0 that turned up on the Japanese marketplace site Mercari on 8 November 2020,http://web.archive.org/web/20210123110734if_/https://www.mercari.com/us/item/m97465145797/ and were later sold a couple months later in January 2021. The buyer of these disks is unknown, meaning these are currently lost.
Among the various sets of disks seen in the photos were disks with these labels:
* 09-09-1985 Beta Release (Desktop Applications disk)
* 09-25-1985 Retail Beta Release (date is crossed out, meaning it was possibly overwritten at some point)
* 09-30-1985 Retail Beta Release

Windows 10/Windows Update builds

When the first Technical Preview build was released to the general public, it offered a preview builds feature which allowed Insiders to download and upgrade to the latest versions of Windows 10 from Microsoft's development branches, which contained the latest code and feature changes. The feature only worked when Microsoft released a new build on the Beta Channel (formerly called the Slow ring) and made it accessible to those in who were in the program. With the use of a registry hack, a number of build strings and their ESD names were obtained from the Windows Update infrastructure; however, there was no known way of obtaining these builds.
The (A recompile?) tag indicates that a newer version of a single build from the same branch existed; it is not certain whether the build in question is in fact a recompile or what the purpose behind it is, and furthermore why both versions exist together in the analysis (i.e.: not replaced by a newer version but both are kept).
Builds that were found in the Windows Update infrastructure are located in the following subpages:
== Threshold 1 ==
* 9xxx Builds - 9778 to 9935
* 100xx Builds - 10000 to 10074
* 101xx Builds - 10100 to 10248

Windows 10X build 18941

Windows 10X build 18941 is a build of Windows 10X. The original Windows System Kit of this build was shared publicly on 18 November 2024 alongside build 18985.
This build, interestingly, uses a monochrome Microsoft icon which is similar to the one seen in early Windows 11 development builds. And whenever hovered on it, it turns into a Microsoft logo. This is one of the earliest builds to include resizable windows in Windows 10X development.
== Changes ==
* The out-of-box experience maybe skipped during new installation.
* Whenever the single screen composer is enabled, the windows become resizable.
* The options for changing the alignment of the taskbar has been added.
