How to Fix Slow Mounting of ISO Image Files on Windows 11?

Does ISO Image File Mounting Slowing on Windows PC. Here is the Simple Guide to Fix Slow Mounting of ISO Image Files on Windows 11.

Are you experiencing slow mounting of ISO image files on Windows 11? In this guide, I have explained some tips and tricks to fix it for you. First, we need to understand what mounting ISO image files means.  Mounting allows you to create a virtual CD/DVD-ROM drive on your computer and access the contents of the ISO file as if you had inserted a physical CD or DVD into that drive.

An ISO file is a disk image that contains all the files and folders of an optical disc. It is the same as that of a CD or DVD. Mounting an ISO file allows you to access the files and folders on the disc without actually having to insert the physical disc into your computer’s optical drive.

To mount an ISO file, you can use a program that creates a virtual drive, such as Windows Explorer, or third-party software like Virtual CloneDrive, WinCDEmu, or Daemon Tools. Once the virtual drive is created, you can open the mounted ISO file in the same way you would access files on regular CDs. Simply navigate through folders and launch the necessary programs.

Why Mounting of ISO Image Files is Slow on Windows 11?

Sometimes, the users complain that the ISO image file is not mounting or the process is way too slow. Let us know the common reasons why this may happen.

If the ISO image file is very large, completing the mounting process may take some time. When you mount an ISO file and your PC is already running many resource-intensive tasks or has limited resources, mounting the ISO image file slows down significantly.

Keep in mind that if you are trying to mount an ISO image file from a hard disk drive (HDD), the process may be slower compared to mounting it from a faster solid-state drive (SSD). If there are driver issues on your computer, it could result in slow performance when mounting ISO image files.

Top Ways to Fix Speed Up Mounting of ISO Image Files on Windows 11

Now, let us go through the troubleshooting part to ensure that ISO image files are mounted without any hassles.

1. Close other Applications While Mounting an ISO File

This tip is a no-brainer. When you are mounting large ISO files, close the other resource-intensive tasks on your computer. Not every task is urgent at all times. When the system resources get free, they can be directed in efficiently mounting the ISO image files.

2. Restart the Computer

Sometimes, randomly the ISO image file stops mounting or becomes very slow. Restarting the PC can fix the issue.

  1. Press the Windows key. It will bring up the search console.

3. Upgrade from HDD to SSD

Solid-state State Drive storage is far better and faster than HDD [Hard Disk Drives] in today’s date. SSD uses flash memory to store data, as opposed to traditional hard disk drives (HDD) that use spinning disks and magnetic storage.

That makes SSDs faster, more efficient, and more reliable than HDDs because they have no moving parts. This means that they are less prone to mechanical failures. They are also quieter, lighter, and use less power than HDDs.

So, upgrade to a new PC with an SSD, or you may check with your nearest computer repair point if it is possible to replace the existing HDD on your PC with an SSD.
