Disable Low Disk Space Warning (Windows 11)

Quick Tips

• The “Low Disk Space” warning is useful, but can get annoying after a while.
• To remove it, you can use the Registry Editor.
• For partitioned disks, you can remove their visibility via DiskPart.
• If you’re looking for space to clear, you can start with Windows Temporary files in Disk Cleanup.

Have you been running out of disk space on one of your drives? If you are, you’re probably aware of it thanks to repeated warnings from Windows 11, but they might be a bit unwelcome after the fourth or fifth pop-up. Disabling these alerts, though, is a pretty simple task. In this article, we’re going to show you how to do just that.

How to Disable Low Disk Space Warning on Windows 11

There are a few ways to get rid of the “Low Disk Space” warning on your machine. We’ve outlined the steps to follow for each below. Let’s get started:

Disable via the Registry

The Registry contains a lot of important settings for Windows, and changing anything without knowing what to do could end in disaster. However, it’s also one of the best ways to disable annoying features. Don’t worry, we’ll guide you along the way:

Step 1. Open the Run dialog (Win + R) and type “regedit” before pressing (Ctrl + Shift + Enter) to run the process as administrator.

Step 2. In the Registry Editor window, navigate to the following: “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies.” You can copy and paste this in the Pathing bar, too.

Step 3. Right-click on the “Policies” folder in the sidebar and choose “New Key” from the Context menu.

Step 4. Name the new key “Explorer” and press “Enter.”

Step 5. Right-click on the new “Explorer” key in the sidebar and choose “New > DWORD (32-bit) Value” from the Context menu.

Step 6. In the main window, you’ll see a new value appear. Click the value once and rename it “NoLowDiskSpaceChecks” and press “Enter.”

Step 7. Double click the value and set the “Value data” from “0” to “1.”

Step 8. Press “OK”.

Step 9. Restart your machine, and you shouldn’t be troubled by the message again.

Remove Disk From Listing (Partition Only)

If you’ve got a partitioned disk drive meant for storage or backup that’s suddenly become visible following a Windows update (like 24H2), then you can get rid of the “Low Disk Space” message and the drive’s visibility in one go. Here’s how:

Step 1. Type “DiskPart” into the Search Bar and choose the option that appears.

Step 2. Select the visible partition by typing “select volume [letter]” and press “Enter.”

Step 3. Type “remove letter=[letter]” and press “Enter” to remove the disk letter and return it to invisibility.

Step 4. Restart your PC and see if the disk (and the warning) has gone.

Clean Your Temporary Files

Another way to ensure the “Low Disk Space” warning doesn’t pop up is to free up some space on your drive. It sounds obvious, but the temporary files stored on the main drive of PCs are often overlooked as a way to free up a lot of space. Here’s how to run Disk Cleanup:

Step 1. Open the Run dialog (Win + R) and type “cleanmgr” before pressing “Enter.”

Step 2. Select the drive you want to clean up from the drop-down list and press “OK.”

Step 3. Give your PC a few minutes to scan for areas to clean.

Step 4. The Disk Cleanup window will show you files that can be deleted. Check the box next to “Temporary files” and any other group that you don’t need.

Step 5. Press “OK,” and the deletion process will begin.
