USB 写^{(USB Write)}访问或USB 写^{(USB Write)}保护是可以为任何USB 数据^{(USB Data)}存储启用的安全功能。启用USB^(USB)写访问的主要目的是维护USB数据存储的完整性。在这篇文章中，我们将向您展示在Windows 10上启用或禁用^{(Windows 10)}USB 写入^{(USB Write)}访问的方法。

通过启用写保护，磁盘中的数据将不会被修改。因此，它可以防止PC 用户对USB 数据存储的^{(USB Data)}病毒攻击或未经授权的文件从Windows 10操作系统访问/复制到USB驱动器。^(USB)

USB驱动器有两种可用的写^(Write)保护，即：

• 硬件写保护。
• 软件写保护。

硬件^(Hardware)写保护主要在读卡器或软盘中可用。在硬件写保护中，读卡器的侧面会有一个机械开关，在软盘中，左下角会有一个黑色的滑动块。一旦拉动此开关，则启用写保护。要关闭/禁用，只需向下滑动开关。

在这篇文章中，我们将了解如何使用软件方法启用或禁用USB 写入访问。^{(USB Write)}

How to enable or disable USB Write Protection on Windows 10

USB Write access or USB Write protection іs the seсυrity feature that can be enablеd for any USB Data storagе. The main purpose of enabling USB wrіte access is to maintain the intеgrity of USB data storage. Іn this post, we will show you the ways you can enable or disable USB Write accеss on Windows 10.

By enabling Write protection, the data in the disk will not be modified. Thus it can prevent virus attack on USB Data storage or unauthorized file access/copy from Windows 10 OS to a USB drive by PC users.

There are two kinds of Write protection available for USB drives viz:

• Hardware Write Protection.
• Software Write Protection.

Hardware writes protection is mostly available in the card reader or floppy disks. In hardware write protection there will be a mechanical switch at the side of the card reader, in floppy, there will be a black slidable block in the lower-left corner. Once this switch is pulled over then the write protection is enabled. To turn off/disable just slide down the switch.

In this post, we are going to look at how to enable or disable USB Write access using the software method.

Enable or disable USB Write Protection on Windows 10

You can enable or disable USB Write Protection on Windows 10 either of two ways via:

1. Registry Editor
2. Local Group Policy Editor

Let’s take a detailed look at the steps involved concerning each method.

1] Turn On or Off USB Write Protection via Registry Editor

• Next, double-click on WriteProtect to edit its Properties.
• Input 1 in the Value data box and press Enter to save the change.
