Enable/Disable Hard Disk Free Space Warning Balloon Tip

By default, Windows posts an alert when the amount of free space remaining on your hard disk falls below 10 percent.

To alter this behavior, edit:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services \LanmanServer\Parameters

Add Value DiskSpaceThreshold with a type of REG_DWORD and set it to the percentage of free disk space remaining before an alert is sent. The allowable range is 0 - 99 percent.

Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters]
Value Name: DiskSpaceThreshold
Data Type: REG_DWORD
Data: 0 - 99
