posted on May 21, 2025

Deleting an old version of Windows can free up significant space on your computer. You start by accessing the storage settings, then navigate to the system files to locate the previous Windows installation. With a few clicks, you can safely remove these old files, giving your computer a fresh start and more room to breathe.

How to Delete Old Version of Windows

Deleting an old version of Windows helps declutter your computer and can improve performance. Follow these steps to safely remove the unnecessary files.

Step 1: Open Storage Settings

Access the storage settings on your computer by going to the Start menu and selecting "Settings."

Once you’re in the settings, click on "System" and then "Storage." This area shows you a breakdown of what’s using up space on your computer, and it’s where you’ll find the option to remove old system files.

Step 2: Select ‘Temporary Files’

Click to view the storage details, then select "Temporary files" from the list.

In this section, you can see various files that can be removed safely. Look for the "Previous Windows installation(s)" option, which refers to old versions of Windows stored on your device.

Step 3: Check ‘Previous Windows Installation(s)’

Locate and check the box next to "Previous Windows installation(s)."

By checking this box, you’re telling your computer that you’re ready to delete these old files. Ensure that you really want to do this because once these files are gone, you can’t revert to the old Windows version.

Step 4: Click ‘Remove Files’

After checking the necessary boxes, click "Remove files" to begin the deletion process.

This will start the process of deleting the old Windows version. It might take a few minutes, and your computer might seem busy while it works, but just let it do its thing.

Step 5: Restart Your Computer

Once the files are removed, restart your computer to complete the process.

Restarting helps finalize the changes and ensures your computer is running smoothly without the clutter of old system files hanging around.

After completing these steps, your computer should have more free space and potentially improved performance. The old version of Windows will be gone, freeing up valuable storage and making your system run a bit more smoothly.
