How to Remove Write Protection on Windows 11

What to do if you can't make changes to files on USB drives and SD cards

What to Know

  • Right-click file, open Properties, clear Read-only box.
  • Run diskpart's attributes disk clear readonly command for devices.
  • Toggle physical read-only switch (if there is one).

This article explains how to remove write protection on a file, USB device, or SD card. Disabling write protection allows you to make changes (i.e. write) to files instead of just view (i.e. read) them.

Is It Possible to Remove Write Protection?

Removing write protection involves clearing the read-only attribute, and it's completely possible to do this for files, folders, and entire storage devices. How this is done is different depending on what you're dealing with, since there's both hardware and software write protection techniques.

The clearest way to confirm a file is write-protected and not just experiencing an unrelated issue, is if you get a read-only error when trying to overwrite it.

<file name>
This file is set to read-only.
Try again with a different file name.

If an entire disk is write-protected, you'll see The media is write protected, if you're trying to make changes from Command Prompt. File Explorer displays this:

The disk is write-protected.
Remove the write-protection or use another disk.

How Do I Remove Write Protection on a File?

Taking a file out of read-only mode is extremely easy. It's as straightforward as opening the file's properties and clearing the read-only check box.

  1. Right-click the file and choose Properties. You can also get there by left-clicking once and opening the three-dot menu from the top of File Explorer.

  2. Select Read-only to clear the box.

  3. Select OK to save the changes.

Why Can't I Remove Write Protection on USB Devices?

You can! It just might be tricky because USB devices deal with write protection differently than files.

For example, some devices have a physical switch which can be toggled on and off to enable or disable read-only mode. Just make sure the switch in the correct position to enable write mode.

Windows is responsible for removing write protection on USB devices without a switch, but it's not as straightforward as clearing a 'read-only' check box. You'll notice this if you open the device's properties; this check box is missing. Instead, you can either run some commands or edit the Windows Registry.

Run Diskpart Commands

Accessible via Command Prompt, the diskpart command is one way you can edit the read-only attribute for a USB device.

  1. Launch the Run dialog box and enter diskpart. You can get there by right-clicking the Start menu or searching for Run.

  2. Once Command Prompt opens, enter list disk.

  3. Enter select disk, followed by the number corresponding to the USB device you wish to remove write protection. The quickest way to verify which one to pick is to look at the 'size' or 'free' column, but Disk Management could also be helpful.

    In our example, we're working with Disk 1, so we'd enter this:

    select disk 1
  4. After the confirmation message stating the disk has been selected, enter this command:

    attributes disk clear readonly
    The DiskPart attributes disk clear readonly command in the Windows 11 Command Prompt.

    Replacing the word 'clear' with 'set' will enable write protection.

Edit the Registry

This method is a bit more involved and risky if you're unfamiliar with the Windows Registry. But if you follow along closely and back up the registry beforehand, this serves as another way to remove write protection.

This method affects all removable devices used by your computer, not just a particular disk like the diskpart method above. However, you'll probably only need to use this technique if read-only mode was enabled this way, in which case this is simply a reversal.

  1. Search for Registry Editor and open it to this location by expanding the folders in the left column:

  2. Find StorageDevicePolicies within the Control key. If you don't see it, create it by right-clicking Control and going to New > Key.

  3. Open StorageDevicePolicies and locate WriteProtect in the right area. If you don't see it, create it by right-clicking StorageDevicePolicies and going to New > DWORD (32-bit) Value.

  4. Double-click WriteProtect and set Value data to 0 if it isn't already.

    If you enter 1 instead, it will turn on read-only mode for all current and future removable devices.

  5. Close Registry Editor and reboot your computer.
