What Is Windows 3.0, 3a And Its Types?

Windows 3.0 is the third major release of Microsoft. The first time it was released was on May 22, 1990.

Out of all the Windows 3 versions, the one who the most popular/used was Windows 3.11. The release of Window 3 was just an experiment or rough prototype to check it. Microsoft never expected windows 3 will get this much attention from the users.

With the release of Windows 3, it spread like a wildfire. Day by day the user’s number was increasing.

 Even though MS-DOS was also a success but not like windows 3 and its other versions. With MS-DOS as the first step, Microsoft bought many OS in the market. However, out of them all, Windows 3.0 was a deal-breaker.

With completely different User Interface as compared to previous Windows versions like Windows 2 or MS-DOS.

You were now able to do things like multitasking, with ease. With availability to use mouse and initiative graphics, now you are not compelled to type an entire paragraph to perform some simple tasks.

A single click on the icon will start the program to work. There is no need to memorize all those codes just to open a single folder.

Microsoft made it easier by creating shortcut icons to have more like a clear and straight forward user interface. You also have the option to drag and drop the files in Windows 3.0.

You can also perform things like adding colors, text, headers, charts, and pictures on your document in Windows 3.0.

The word processor was also available. You were able to write anything and can make the headers according to your need big, small, change the font of your words. It can even detect incorrect words as well.

When Windows 3.0 arrived it was a chance for many to use it. However, still, users were highly in use for DOS (which was highly used for gaming). Windows 3.0 was a step to make computers available for every home out there. Which later on was proved correct.

In Windows 3.0 the old MS-DOS was replaced with file and program manager. However, still, to install it you will need to install MS-DOS first on your computer. And after the installation is completed you have the access to use it.
