Windows 1.0x

Windows 1.00 - 1.04 is the Windows 1.0x Era.

Windows 1.00 is the 1st ever Operating System supported by MS-DOS and also the 1st Operating System of Microsoft. The previous OS was MS-DOS, which then became a design language system for Windows 1.00 - Windows Me.

Development
Windows 1.00 had a really long development.

So 1 day, Bill Gates saw the Byte club to make systems. So he really wanted, too, but it took a while, also it took a while for Microsoft to apply colours to an OS. He got from 1 of Apple's houses and tried to make a talk, since they made Mac OS System 0.97 and 1, for him to understand to make 1. (So, this is a theory and I don't want drama in the comments, it will be bad and will get deleted if this happens really soon. So please try to correct me, except doing drama.)

The 1st ever build was the Windows 1.0 Byte Build. This build was then posted by the magazines which made more builds about this.

The 1st builds to have colours were the Tandy 2000 builds. Bill Gates made so many applications / programs and some programs finally had colours.

The differences is, the apps are not finished at all, because some things might be squares in REVERSI, because the RTM used circles except for squares.

Microsoft then did the beta and Alpha releases, after the Tandy 2000 builds, to get a lot more touches to Windows 1.0 and finish it.

Then, Windows 1.00 was finally finished and was officially released publicly at 6th November 1985.

Updated Kernels of Windows 1.0x
Windows 1.00 had 5 more versions, which actually we're to improve the operating environment of Windows 1.0, and look kind of similar then to Windows 2.0x.

Windows 1.01
Windows 1.01 is an international release of Windows 1.00. It was finally finished and was officially released almost on 14th November 1985 and then intentionally at 20th November 1985.

Windows 1.02
Windows 1.02 added 2 new features to the Windows Environment and was only released in Europe, and was the 1st version that was up to date.

The new features are:


 * The spooler now will say that it will not be plugged in, which that was a good feature for people to understand what's happening to the spooler of their PC.


 * Some programs have been upgraded to version 1.02, when some programs yet apply to version 1.01.

Although, the other things are the same, so skipping ahead to the next version.

Windows 1.03
In Windows 1.03 there are 3 new features. which made the OS have a lot more fun and be more stable and was released somewhere in June - August 1986.


 * Now you can run the license or run the OS with device drivers.
 * A new improved SDK.
 * Updated Control Panel, Paint, REVERSI and Write to Version 1.03, though the others are to 1.02 yet.

Windows 1.04
In Windows 1.04, there are features and changes, also and bug fixes and was released in April 1987, 6 months before the initial release of Windows 2.0x.


 * There's now support for IBM 's new PS/2 computers of their lines.
 * New Boot screen when you start Windows 1.04 for the 1st time and all the time, with changing from the 1987 - 2011 Font logo, and the colour looks a little darker than it used to in previous OEMS.
 * Updated Calculator, REVERSI and Control Panel to Version 1.04, while some of the Programs are still on Versions 1.03.
 * It also had the support for 3.5" Inch floppy disk drivers, except for only having support for the 5.25" inched ones.
 * Now there's the new CGA theme which gets back to the black and white like it used to in previous builds and betas of Windows 1.01, the default theme that now it uses is the EGA ones.

Windows 1.05
Windows 1.05 was only released in China in August 1987.

Windows 2.0x was the next project they needed to do, and was released in late 1987.
