How To Disable Low Disk Space Warning on Windows 11

Running out of disk space on a drive is always a pain, especially when Windows 11 keeps throwing up those “Low Disk Space” warnings every few minutes. It’s like your PC is nagging you for no good reason, even if you already know the drive’s full. Sometimes, these alerts pop up at the worst moments and can be annoying, especially if you’re really not trying to free up space right now. To tame this, there are a couple of tricks that might help you silence those warnings or at least hide the drive from bothering you. They’re not always perfect, and sometimes the warning sneaks back, but hey, it’s better than nothing.

How to Disable Low Disk Space Warning on Windows 11

Basically, there are a few ways to kill the warning, and each has its quirks. Think of it like patching a leaky pipe—some solutions work temporarily, some are more permanent. Your options include editing the registry (which is kinda risky if you don’t know what you’re doing), hiding the disk from Explorer, or just cleaning up temporary files to free some space. Pick what sounds less terrifying and give it a shot. Here are the options, with some extra details to make things smoother.

Disable via the Registry (the hardcore way)

This one works because Windows checks a specific registry setting to decide whether it should show that warning. So changing it basically tricks Windows into thinking everything’s fine on that drive. Just be careful—messing with the registry can cause other issues if you’re not careful. On some setups, the change might not stick until a reboot, but hey, worth a try if you’re desperate to turn off the annoying alerts.

  • Open the Run dialog with Win + R and type regedit. Better to run it as admin, so Ctrl + Shift + Enter.
  • Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies. You can copy this path into the address bar of the Registry Editor.
  • Right-click on Policies, choose New > Key, and name it Explorer. Because of course Windows makes you jump through hoops.
  • Right-click on the new Explorer key, select New > DWORD (32-bit) Value. Name this NoLowDiskSpaceChecks.
  • Double-click that new DWORD and change Value data from 0 to 1. Because that’s how it disables the warning.
  • Hit OK and close the registry editor.
  • Restart your machine. Sometimes it takes a reboot, sometimes not — depends on the setup. On some machines this fails the first time, then works after reboot.

Remove Disk From Listing (Partition Only)

If some storage drive or partition keeps popping up, especially after a feature update like Windows 11 22H2, you might want to hide that partition altogether. Removing the disk letter doesn’t delete data, just hides it from Explorer, which often stops the warning from triggering. This is handy for drives that are for backup or just not needed, but beware—if you need access later, you’ll have to redo the process.

  1. Type diskpart into the Search Bars, launch it as administrator.
  2. List all your disks with list volume so you know which one to target.
  3. Type select volume [letter] (replace [letter] with your drive letter) and press Enter.
  4. Remove the drive letter by typing remove letter=[letter], then hit Enter.
  5. Restart your PC and check if the warning and drive should now be hidden. Sometimes, Windows might still decide to throw a fit, but most of the time, it works like a charm.

Clean Your Temporary Files

Many times, the low disk warning is just because your main drive is crowded with temporary junk. Disk Cleanup tool isn’t revolutionary, but it’s surprisingly effective at freeing up space — especially if you haven’t done it in a while. Clearing out temp files, old system cache, and other redundant data can give your drive a little breathing room, which might stop those nagging alerts.

  • Press Win + R and type cleanmgr. Hit Enter.
  • Select the drive with the warning (probably C:) and click OK.
  • Let it scan for a few minutes — depends on how cluttered things are.
  • In the list, check all the boxes labeled “Temporary files, ” “Thumbnails, ” “Recycle Bin, ” and anything else that looks unnecessary. If you’re not sure, just pick the main ones.
  • Click OK to delete everything. You might see a quick warning; just confirm and wait it out.

Running this a few times a year helps keep things in check, and it might also make that warning disappear for good. Because, honestly, Windows has to make it harder than necessary sometimes.

All these tricks aren’t perfect but can help keep those dreaded warnings at bay. Just remember, if your drive’s actually full or you keep running into space issues, cleaning up or upgrading storage is probably the real fix. But if you just want peace and quiet — yeah, these methods can help.
