Why was “computer is open in Wimserv“ prompted?

The install.wim file (image) caused this error by being in use and mounted. Furthermore, Due to errors I ran into, I needed to delete the install.wim and re-extract it from the source (ISO).

When attempting to delete the mounted install.wim file, it triggered the above error.

Here are some computer is open in Wimserv you can encounter while working with the DISM tool. Error 0xc1570103: The license file was not found in the specified path. Also, see how to fix error 0xc1510114: The .wim file needs to be remounted

How do we resolve this issue?

1: We will have to unmount the install.wim file and discard the changes made. Close the install.wim file to regain the ability to delete it. See the following guide on how to unmount and discard windows images.

- dism /Unmount-Wim /MountDir:C:\path-to-the-mount\Mount-A /discard

2: Alternatively, you may kill the process, as you will not need the installation.wim anyways. After killing the process, just proceed and delete the install.wim file and the mounted image. To do this, follow the steps below.

However, To kill a process in Windows, launch the Task Manager by right-clicking on the taskbar and selecting “Task Manager,” as shown below.

This will open the Task Manager Window. Click on More Details as shown below to get access to the Task Manager menu.

Click on the details page and select “wimserv.exe”. Right-click on the wimserv.exe and click on End Task

You will be asked to confirm if you wish to end the wimserv.exe. Click on End process to end the wim service.exe. After this step is complete, you can delete the install.wim file.
