我们有些人有笔记本电脑，有些人有台式机。但是在所有Windows^(Windows)计算机系统中常见的一件事是，安装操作系统的系统硬盘是C。

Microsoft Windows操作系统始终使用默认字母 C 作为安装所有程序的主硬盘驱动器。如果您曾经安装过新的Windows操作系统，您可能已经注意到Windows 操作系统^{(Windows OS)}安装的默认存储位置是硬盘 C。但是，您可以更改安装位置。

为什么 C 是默认的Windows 系统驱动器号^{(Windows System Drive)}？

你有没有想过为什么微软^(Microsoft)使用 C 作为默认盘符？为什么我们在Windows^(Windows)上默认没有硬盘 A 或 B ？毕竟，A 和 B 在 C 之前！

要知道答案，我们必须回到没有发明硬盘驱动器的过去。今天，我们的计算机系统和笔记本电脑上有足够的存储空间。这是因为它们带有内置硬盘驱动器。但早期的计算机并非如此。早期的计算机没有内置存储空间。因此，他们使用外部存储媒体来存储程序。这些存储介质是软盘^{(Floppy Disks)}。

计算机^(Computer)所有者使用这些软盘^{(Floppy Disks)}来存储他们的数据并运行他们的计算机系统。没有软盘^{(Floppy Disks)}，早期的计算机系统就无法运行。由于软盘是第一个存储数据和运行计算机程序的硬盘^(Disk)，它以字母A命名，由IBM推出。

软盘^{(Floppy Disk)}只有 1.44 MB的存储容量。随着时间的推移，技术得到了升级，用户在他们的计算机系统上获得了两个软盘插槽。^{(Floppy Disks)}那个新的软盘^{(Floppy Disk)}以字母B命名。

使用这些软盘 A^{(Floppy Disks A)}和 B，用户可以在他们的计算机系统上获得更多的存储空间。但是，软盘^(Floppy) 仍然^(Disks)无法存储大量数据。此外，它们不安全，因为它们可能被盗或损坏，因为它们是外部存储介质。

由于软盘^{(Floppy Disks)}的局限性，后来发明了硬盘。^{(Hard Drives)}与软盘^{(Floppy Disks)}相比，第一个硬盘驱动器为用户提供了广泛的存储空间。由于第一块硬盘是在A、B两块软盘^{(Floppy Disks A)}之后发明的，所以得名C。我们可以概括为：

• A：第一张软盘。
• B：第二个软盘。
• C：第一个硬盘。

您可能会想到一个问题，“我可以将硬盘 C^{(Hard Disk C)}的名称更改为 A 或 B 吗？” 好吧^{(” Well)}，这个问题的答案取决于您的计算机系统。如果您没有为软盘^{(Floppy Disks)}保留存储空间，您可以将任何硬盘从 A 重命名为 Z。

您可以在“磁盘管理^{(Disk Management)}”中进行检查。如果您的计算机为 A 和 B 保留空间，它不会显示这两个字母来重命名硬盘。

Why is C the default Windows System Drive letter always?

Some of us have a laptop, and some have a desktop. Βut one thing that is common in all Windows computer sуstems is thаt the system hard drive on whіch the operating system is іnstallеd is C.

The Microsoft Windows operating system always uses the default letter C for the primary hard drive, where all the programs are installed. If you have ever installed a new Windows operating system, you might have noticed that the default storage location for the Windows OS installation is the hard disk C. However, you can change the installation location.

Why is C the default Windows System Drive letter?

Have you ever thought about why Microsoft uses C as the default drive letter? Why do we never get a hard drive A or B on Windows by default? After all, A and B come before C!

To know the answer, we have to go to the past, when the hard drives were not invented. Today, we have plenty of storage space on our computer systems and laptops. This is because they come with built-in hard drives. But this was not the case with the earlier computers. The earlier computers did not have built-in storage space. Due to this, they used external storage media to store the program. These storage media were the Floppy Disks.

Computer owners used these Floppy Disks to store their data and to run their computer systems. Without the Floppy Disks, the earlier computer systems could not be run. Since Floppy Disk was the first hard drive to store the data and run the computer programs, it was named with the letter A and was introduced by IBM.

The Floppy Disk had only 1.44 MB storage capacity. With time, technology was upgraded, and users got two slots for Floppy Disks on their computer systems. That new Floppy Disk was named with the letter B.

With these Floppy Disks A and B, users got some more storage space on their computer systems. But still, the Floppy Disks were not able to store a huge amount of data. Also, they were insecure because they could be stolen or damaged as they were the external storage media.

Due to the limitations of Floppy Disks, Hard Drives were invented later on. The first hard drive offered an extensive storage space to the users as compared to the Floppy Disks. Since the first hard drive was invented after the two Floppy Disks A and B, it got its name C. We can summarize it as:

• A: First Floppy Disk.
• B: Second Floppy Disk.
• C: First Hard Drive.

One question may strike your mind, “Can I change the name of Hard Disk C to A or B?” Well, the answer to this question depends on your computer system. If you do not have reserved storage space for Floppy Disks, you can rename any hard drive from A to Z.

You can check this in the “Disk Management.” If your computer has a reserved space for A and B, it will not show these two letters to rename a hard disk.
