Disable Low Disk Space Warning via Registry

This guide explains how to disable low disk space notification warnings in Windows using the Registry Editor (Regedit). By configuring specific policy values within the registry, you can prevent the operating system from displaying persistent low storage alerts for your drives, allowing you to manage storage thresholds without interruption.

How to Disable Low Disk Space Warnings

Open the Registry Editor
- Press Windows Key + R to open the Run dialog box.
- Type regedit and press Enter.
- Click Yes if prompted by User Account Control (UAC).
Navigate to the Explorer Policies Key
- In the Registry Editor address bar, paste the following path and press Enter:
```
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
```
- Note: If the Explorer key does not exist under Policies, right-click the Policies folder, select New > Key, and name it Explorer.
Create or Modify the Value
- Right-click inside the right pane of the Explorer folder.
- Select New > DWORD (32-bit) Value.
- Name the new value NoLowDiskSpaceChecks.
- Double-click NoLowDiskSpaceChecks, set the Value data to 1, and ensure the Base is set to Hexadecimal.
- Click OK.
Apply Changes to All Users (Optional)
- To apply this setting system-wide across all user accounts, navigate to:
```
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
```
- Create the same NoLowDiskSpaceChecks DWORD (32-bit) value and set its data to 1.
Restart Windows Explorer or Reboot
- To apply the changes immediately, open Task Manager (Ctrl + Shift + Esc), locate Windows Explorer under the Processes tab, right-click it, and select Restart.
- Alternatively, restart your computer.

How to Re-enable Warnings

To restore the default low disk space warning behavior at any time, return to the specified registry path and either change the NoLowDiskSpaceChecks value data to 0 or delete the NoLowDiskSpaceChecks DWORD completely, then restart Windows Explorer.
