Disable Low Disk Space Message in Windows 7 / 8 / 10

At times you may get a Low Disk Space message or notification or warning popup from the right side of your Windows taskbar – You are running very low on disk space on disk. To free space on this drive by deleting old or unnecessary files click here.

Low Disk Space Message

Low Disk Space Message

Well the balloon notification is meant to warn you that you are running out of disk space. But at times you may get it for no apparent reason.

If you feel you are truly running out of disk space, you might want to clean up some disk space.

Windows Vista checks for available disk space every minute, but Windows 7 and later, by default checks for available disk space every 10 minutes, and the pop up remains for 10 seconds. This is by design, keeping in mind certain performance issues.

So it is quite possible that your Windows 8 | 7 may never warn you about this, while you actually consuming disk space, maybe when you are in the process of pasting large amounts of data. It may happen that it warns you when it is too late, ie after 10 minutes!

These are the threshold levels when you may see the pop-ups:

  • Free space less than 200 MB : You are running out of disk space on drive.
  • Free space less than 80 MB : You are running very low on disk space on disk
  • Free space less than 50 MB : You are running very low on disk space on disk
  • No free space remaining : You have run out of disk space on drive.

If you want, you can disable this Low Disk Check through the Windows Registry. Do do so open regedit and navigate to the following key:


Create a new DWORD Value named NoLowDiskSpaceChecks and give it value 1.

You can also always use our Ultimate Windows Tweaker 4 for Windows 10 to do so easily. There are different versions available for Windows 10, Windows 8.1 and Windows 7.

It may therefore be a good idea to check your available drive space if you are planning to write large amount of data onto it.

You can use Disk Cleanup utility or CCleaner to clear up some disk space. If you are now  comfortable with SP1 and if you are sure that you will not need to uninstall the Service Pack, then you may wish to consider removal of several 100 MB of such back up files and reclaim disk space.

If you wish to analyze where your disk space has gone, you can check out Disk Space Fan or Space Sniffer.

The Disk Footprint Tool in Windows8.1 will let you carry out several tasks pertaining to Disk Space usage. You can use it to take snapshots, summaries, analyze disk usage, anonymize, compare growth over time using disk growth study and more.

    Is there any method to specify different thresholds for different drives?

  • Brian Carr

    nice tweak. could you tell me how do you put it back to default setting?

  • http://www.thewindowsclub.com/about Windows Club

    Victor: I’m afraid, you cannot specify different thresholds.

    Brian: You can delete the created DWORD NoLowDiskSpaceChecks OR give it a value “0” (zero) or if you are using our Ultimate Windows Tweaker, re-enable the option and click Apply.

    Hi Brian,

    I have been disabling this notification ever since I remember. It is even disabled now with no issues. But since your experience differs, I think its good that you have renabled it. :)

    I have met the “low disk space” on my Windows 7 Ultimate recently. And I googled an article How to solve Windows 7 “low disk space” warning and solve my problem successfully. I share this article hoping can help anyone else.

    thx for sharing. good tool. thumb up

  • wormocious

    I do not have a folder labeled “explorer” under “policies”, can I create this DWord in the “polcies” folder for the same effect?

  • Lakeshia Davis

    No, you would create the Explorer key, and put the DWord there. Or alternatively, put in the same place, but starting from HKLM rather than HKCU.

  • Andrew

    I did this and I still get the notifications.

    Use our freeware Ultimate Windows Tweaker to disable it. Let us know if it worked for you. http://www.thewindowsclub.com/ultimate-windows-tweaker-3-windows-8

  • Awesomeness

    Put the fix in the HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER

  • Johnny

    there is no fking
    in my windows 7

  • Bear cawdy

    i see no such thing when i open up the registry

  • Digi

    If you’re only missing the “Explorer” part, right-click on Policies and click New > Key, name it “Explorer”.

  • Meiamo

    Also remember to reboot the computer after the changes.

  • Ashley J Taylor

    I am using windows 10 and I don’t have last folder in the directory called explorer. I have added the new Dword value under the polices but I still experience this warning issue. I have multiple hard drives in my computer so it is giving me unnecessary warnings about hard drives that are full ( I know don’t need a warning for this) that aren’t part of the local disk or operating system.

    Use our Ultimate Windows Tweaker to do this in a click: http://www.thewindowsclub.com/ultimate-windows-tweaker-4-windows-10

  • Dan

    This has not worked. Tried numerous times. Initially there was no folder call Explorer folder in the Policies folder so made one. There was an Explorer folder in the CurrentUser directory but that did not have a NoLowDiskSpaceCheck line. I added one there for good measure but no joy. From my reading, I am not the only one for whom this fix did not work.


  • William Crisp

    I want to delete annoying low disk space message in windows 10

  • Olatunji

    Which setting on Windows Ultimate Tweaker do I need to change? I must be overlooking it.

  • leafwarbler

    ” HKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorer

    Create a new DWORD Value named NoLowDiskSpaceChecks and give it value 1″

    So can I change the value to 2 ? I heard from one of my friends, he says i can change the value to 2, but it obstructs every warning when Windows gets wrong.

    Or you can turn of and hide the notification in the properties of the taskbar. right click the taskbar and select properties and then show hide notifications and hide it.
