Running out of disk space on a drive isn’t exactly fun, especially when Windows 11 keeps throwing those annoying “Low Disk Space” warnings every few minutes. Yeah, after a while, they start to feel kind of relentless, and honestly, sometimes you just wanna turn them off without digging through tons of settings. So, if you’re tired of the pop-ups, here are a few tried-and-true ways that actually work to silence those warnings — at least temporarily. These methods can help if you’re trying to focus on something or if the warning is just plain distracting. Just keep in mind, disabling them doesn’t fix the actual space problem, but it does make your experience less cluttered with alerts.
How to Disable Low Disk Space Warning on Windows 11
There are a few different routes to kill that warning. Some are quick registry tricks, while others involve managing your disks directly or cleaning up space. Each has its own pros and cons, so pick what fits your situation best. On one PC, disabling via the registry worked like a charm — on another, removing the drive from the list was easier. It’s one of those “try and see what sticks” kind of deals. Expect that after doing these, the warning should stop bothering you, but if your drive is really full, still address that eventually.
Disable warning via the Registry (probably the most common fix)
This is kind of a brutal way but makes sense if you just want Windows to shut up about low disk space. The registry controls a lot of behaviors, and toggling a specific value here can stop the pop-up from showing. Not 100% foolproof, but on a lot of setups, it does the trick. Oh, and before editing the registry, it’s a good idea to back it up — just in case. You might need to reboot after, so don’t forget that part.
- Open the Registry Editor: press Win + R, type
regedit, then press Ctrl + Shift + Enter to run as admin. If a UAC prompt shows up, agree to it. - Navigate to the Policies folder: go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies. You can just copy-paste the path into the Registry editor’s address bar, if that’s easier.
- Create a new key: right-click on Policies, choose New > Key, and call it Explorer.
- Add a DWORD: right-click inside the Explorer folder, pick New > DWORD (32-bit) Value. Name it NoLowDiskSpaceChecks.
- Modify its value: double-click on NoLowDiskSpaceChecks and set the Value data to 1. Click OK.
- Reboot your PC: this usually applies the setting, and hopefully, the warning won’t bother you anymore. Sometimes it takes a restart or two for the registry change to fully take effect.
Not sure why, but on some machines, even this tweak isn’t enough — still get alerts once in a while. Still, it’s a solid first try if you’re sick of dismissing warnings all day.
Remove Disk From Listing (Partition Only)
If you’ve added a storage drive or a backup partition recently and suddenly it’s spamming that same warning, or it just bothers the clutter in your Explorer, this can help. Sometimes disks show up because Windows detects them but you don’t want them to be visible or alerting about their space. Removing the mount point or drive letter can take care of that—pretty handy if you’re only using a drive for backups and don’t need it relentless in your face.
- Open Command Prompt: type
diskpartin the search, right-click, and choose Run as administrator. - List volumes: type
list volumeand hit Enter. Find the volume or partition you want to hide. - Select the volume: type
select volume [number], replacing [number] with the volume number or letter, then Enter. - Remove the drive letter: type
remove letter=[letter](likeremove letter=D) and press Enter. This makes the drive invisible in Explorer and might stop the warning if Windows no longer tracks it.
It’s kind of weird, but sometimes Windows still reports space issues even after removing the drive letter — depends on how the system manages mount points. After doing this, restart the PC and see if the warning disappears. On some setups, it really works like magic, but on others, not so much. The key is, if you’re not using that drive for anything critical, hiding it can save you some trouble.
Clean Your Temporary Files
Sometimes the simplest fix is just freeing up space. Never underestimate how much temporary junk can pile up. Disk Cleanup is built into Windows, and it’s still pretty reliable. Clearing out these files not only gives you more breathing room, but it might also stop the warning from popping up so often — because, let’s face it, a full drive is a full drive.
- Launch Disk Cleanup: hit Win + R, type
cleanmgr, and press Enter. - Select the drive: pick the main system drive (usually C:) and click OK.
- Scan: let it run — it might take a minute or two.
- Choose what to delete: check off Temporary files and any other categories you’re comfortable removing, like downloaded program files or Recycle Bin if needed.
- Confirm: click OK, then let the cleanup run. Might take a few minutes depending on how much there is to clear.
It’s kind of gross how many temp files accumulate over time — doing this every so often keeps things tidy and, often, quiets down those nagging warnings.
This collection of tricks isn’t perfect, but they should give a decent shot at stopping that warning without diving into more complicated settings or risking system stability. Always good to keep an eye on actual disk health though, because if space issues persist after these, that probably means it’s time to actually clear some space for real or upgrade your storage.
