How Much Is Free Space on Hard Drive Required for 64-Bit Windows 8.1?

For upgrading to Windows 8.1, you require at least 2 GB RAM for 64-bit and around 1 GB for 32-bit. You also need 20 GBs of hard disk space for 64-bit or 16 GBs for 32-bit. You also need a compatible graphics card as well as a speedy processor.

– Checking Already Available Hard Disk Spac

One of the first factors you have to check in your current computer before deciding to upgrade it to Windows 8.1 is the amount of space that needs to be present in the hard disk drive.

It is essential to remember that the more area you have on the hard disk, the more content you will be able to store on your PC.

If you want to download lots of content, such as various games, audio tracks, movies, documents, and applications, then it is ideal to have a lot of free disk space on the hard drive.

If you wish to download Windows 8.1 on your computer in the 64-bit version, you will need around twenty GBs on the hard disk. On the other hand, if you wish to do the smaller 32-bit format of Windows 8.1, then the minimum requirement would be sixteen gigabytes of space.

While this is the minimum requirement to download the operating system on your computer, you will need more space if you intend to keep lots of data on your computer, so keep that in mind when you upgrade to Windows 8.1.

– Understanding RAM Requirements

If you want to clean install the 32-bit version of Windows 8.1, your computer must have at least 1 GB (1 gigabyte) of RAM. For the 64-bit operating system, at least 2 GB (2 gigabytes) is required.

Understanding RAM Requirements

To make your computer perform faster, comfortably run many applications, and multitask, you should keep RAM of higher values. If you need to work on memory-consuming apps, play modern games, or watch high-definition movies, ensuring more RAM on the device is recommended.

– Requirements for the Graphics Card

If you are looking for the smoothest way to install Windows 8.1 on your current computer, you will also need to make sure that the computer’s graphics card is compatible with this high-end version.

While the general requirement to run this version of Windows on your computer is having a DirectX 9 graphics card from Microsoft along with the WDDM driver, some extra features of Windows 8.1 might require a more powerful graphics card, such as DirectX 10.


– The Speed of the Computer’s Processor

Another essential prerequisite for installing or upgrading to Windows 8.1 is a fast computer processor since the pace at which your apps operate is directly tied to the capacity of your computer. Your computer’s ability to perform computations in lesser time due to a faster CPU will enable speedier app performance.

To operate Windows 8.1, your computer’s processor must be at least 1 GHz. It is advised that you retain a processor that can easily manage this load if you want a high-performance computer and want to run CPU-intensive apps and software like 3D rendering programs or high-end games.

– Windows 8.1 Requirements for Extra Files

Keep in mind that specific additional requirements must be met to install and use various apps on Windows 8.1. Having a computer with a screen resolution of 1024 x 768 and a steady internet connection is necessary to visit the Windows store and download and run programs on your computer.
