Critical value for optimizing insufficient disk space warning

In general, Windows warns you when the partition's disk space is less than 10%, but you can modify the percentage of disk usage for the warning, rather than having the system follow the instructions.

Run Registry Editor, open Hkey_local_machinesystemcurrentcontrolsetserviceslanmanserverparameters, and then locate the Diskspacethreshold key value entry, Change the value to "7" (Windows warns when the partition's disk space is less than 7%).

Diskspacethreshold uses decimal notation, the range of 0~99 between the children.
