DISM Error 87 on Windows 11

Facing the DISM Error 87 on Windows 11 and don’t know how to fix it?

The system files of your PC may occasionally get corrupted due to various reasons. But you can resolve the issue by using DISM or Deployment Image and Servicing Management. However, while using this command-line tool, users have to be extra careful as any mistake will result in the DISM Error 87 on Windows 11.

DISM is an essential tool in Windows OS. Its main function is to organize virtual disks of your PC by servicing WIM, Full Flash Utility files, VHD, and so on. If anything goes wrong with this tool and you start receiving the DISM Error 87, it’s important to understand what causes it in order to accurately resolve the issue.

Some of the most common reasons include executing incorrect commands, incorrect Windows 11 installation, not using Command Prompt with administrative privileges, ignoring or blocking some essential updates, using the wrong DISM versions, etc. But don’t fret! All these factors can be easily solved by following through with this guide.

So without further delay, let’s get started!

1. Ensure You’re Running the Correct Command.

As mentioned earlier, the DISM Error 87 on Windows 11 often occurs because users mistakenly run the wrong command in Command Prompt or Terminal. So it is recommended to start off with the most basic solution. 

You just need to make sure you’re not making any typos while typing the command. Look for any incorrect spacing and spellings and ensure you’re not adding any slashes where it’s not required. When that happens, the Command Prompt will fail to read and execute the command properly.

Furthermore, if you’re copying and pasting a command from a website, it’s best to use a reliable source. And before running it on the prompt, verify that it’s error-free.

2. Launch Terminal or Command Prompt With Admin Rights.

When repairing or replacing the damaged system files using DISM, it’s mandatory that you open the Command Prompt with administrative privileges. If you don’t, you won’t have complete access to the system’s settings.

Therefore, try Command Prompt with admin rights by following the steps below:

  1. Firstly, click on the Start Menu, and in the search bar, type in ‘Terminal’. 
  2. Next, right-click on Terminal from the top search results and select Run as administrator

Once done, execute a few commands to see if the problem is solved or not. 

3. Run CHKDSK.

CHKDSK or Check Disk is a command tool that aims to check the file system integrity and displays the status report for a specific volume. Additionally, it will fix all errors diagnosed in that volume, or at least attempt to. Hopefully, this method will also eliminate the DISM Error 87 on Windows 11.

Follow the steps below to go about this method:

  1. Start by running Windows Terminal as an administrator. To do so, go to the Start Menu and search ‘Terminal’. 
  2. Right-click on Terminal from the search results and choose Run as administrator
  3. Next, click on Yes from the User Control Account.
  4. Open Command Prompt in a separate window by pressing Ctrl + Shift + 2 keys from your keyboard. 
  5. Now, copy and paste the following command and then hit the Enter key:
chkdsk/f
